The terminal devices 2 ₁ , 2 ₂ , ..., 2 _n are smartphones or tablets, but may also be desktop PCs (Personal Computers) or notebook PCs, etc. In the following, when each of the users U ₁ , U ₂ , ..., _Un is referred to without distinction, it may be described as a user U, and when each of the terminal devices 2 ₁ , 2 ₂ , ..., 2 _n is referred to without distinction, it may be described as a terminal device 2.

The information providing device 1 collects user information, which is information about users _U1 , _U2 , ..., _Un, from terminal devices ₂₁ , ₂₂ , ..., _2n (steps _S11 , _S12 , ..., _S1n ). The user information includes information on a plurality of attributes related to user U. The plurality of attributes include, for example, the location of the base of user U, attributes of the base of user U, attributes of user U, and the like. The base of user U is the user's home, but may be a place other than the home set by user U, or may be both the home and a place other than the home.

The evacuation information providing device 4 collects location information indicating the locations of users _U1 , _U2 , _... , Un from terminal devices ₂₁ , ₂₂ , ..., _2n (steps _S21 , _S22 , ..., _S2n ). The evacuation information providing device 4 determines the evacuation status of each of the multiple users _U1 , _U2 , ..., Un based on the location information indicating the locations of _{users U1 , U2} , ..., Un collected from terminal devices ₂₁ , ₂₂ , ..., _2n .

The information providing device 1 collects evacuation information including information on evacuation in response to a disaster and information indicating the evacuation status of each of _the users U ₁ , U ₂ , . . . , Un from the evacuation information providing device 4 (step S3).

The information regarding the evacuation sites ₇₁ and ₇₂ includes information indicating the locations, capacity, and area of the evacuation sites ₇₁ and _72. The information regarding candidate evacuation routes to the evacuation sites ₇₁ and ₇₂ is, for example, information regarding a plurality of travel routes between the location of the base of each user U and each of the evacuation sites ₇₁ and _72. Hereinafter, when the evacuation sites ₇₁ and ₇₂ are referred to without being individually distinguished, they may be referred to as evacuation site 7.

The information indicating the evacuation status of user U includes information indicating whether user U is before evacuation, in the process of evacuation, or has already evacuated, information indicating the location of user U if user U is in the process of evacuation, and information indicating the location and name of the evacuation site if user U has already evacuated.

The information providing device 1 determines information to be provided, which is information related to evacuation appropriate for the user _U1 , who is the user _U before evacuation (step S4). The information to be provided determined by the information providing device 1 includes, for example, information indicating the evacuation site 7 of the user _U1 , the evacuation route which is the travel route to the evacuation site 7, and the timing of evacuation to the evacuation site 7.

For example, based on the evacuation information, the information providing device 1 judges the current or future congestion degree of each of the evacuation sites ₇₁ , _72. Then, based on the location of the base of the user U, the attributes of the user U, the evacuation route to each of the evacuation sites ₇₁ , ₇₂ , the current or future congestion state of each of the evacuation sites ₇₁ , ₇₂ , the information providing device ₁ determines the evacuation site 7 of the user U1, the travel route to the evacuation site 7, and the timing of evacuation to the evacuation site 7, etc.

The information providing device 1 transmits the information to be provided determined in step S4 to the terminal device ₂₁ of the user _U1 before evacuation, thereby providing the information to be provided determined in step S4 to the user _U1 (step S5).

The evacuation action information includes information such as multiple disaster prevention actions to be proposed to the user U, the timing of proposing each disaster prevention action, and the order in which the disaster prevention actions are proposed.

3.2.3. Expected danger determination information storage unit 22
The assumed danger level determination information storage unit 22 stores assumed danger level determination information including first notification information according to a hazard environment, a base environment, and a surrounding environment.

Figure 6 is a diagram showing an example of assumed danger level determination information stored in the assumed danger level determination information storage unit 22 according to the embodiment. The assumed danger level determination information shown in Figure 6 is information that includes first notification information in the "hazard environment", "base environment", and "surrounding environment", etc.

"Hazard environment" is information indicating the hazard environment classified according to whether or not the base of user U is included in a flood-prone area or a landslide warning area. Specifically, "hazard environment" includes information indicating four hazard environments: included in a flood-prone area, not included in a flood-prone area, included in a landslide warning area, and not included in a landslide warning area.

"Base environment" is information indicating the environment of user U's base itself, and in the example shown in FIG. 5, it is information indicating the attributes of user U's base, which is "detached house/apartment building, 1st or 2nd floor" or "apartment building, 3rd floor or higher." "Detached house/apartment building, 1st or 2nd floor" indicates that user U's base is a detached house or the 1st or 2nd floor of an apartment building, and "apartment building, 3rd floor or higher" indicates that user U's base is on the 3rd floor or higher of an apartment building.

Note that the "base environment" is not limited to the example shown in FIG. 6. For example, the "base environment" may be a "one-story detached house/first floor apartment building," a "two-story detached house/second floor apartment building," a "three-story detached house/third floor apartment building," or an "apartment building with four or more floors." Furthermore, the "base environment" may be further categorized by building type, age, structure, and the like in addition to building attributes.

"Surrounding environment" is information according to the surrounding environment of user U's base, and includes "Applicable" or "Not Applicable". "Applicable" indicates that there is a river or cliff near user U's base, and "Not Applicable" indicates that there is no river or cliff near user U's base.

As described above, the expected danger level determination information includes the first notification information. The first notification information is information notified to the user U according to the expected danger level, which is the level of danger expected according to the hazard environment, base environment, and surrounding environment of the user U.

For example, in the example shown in FIG. 6, if the location of user U's base is included in an area expected to be flooded, the first notification information is "Risk of *", with the "*" portion being issued according to the flood depth rank code. For example, if the flood depth rank code is "1", the "*" portion is "flooding below the floor (maximum 50 cm)", and if the flood depth rank code is "2", the "flooding above the floor (maximum 0.5 to 3 m)". The flood depth rank code is determined by the processing unit 12 for each user U based on the location of user U's base, building attributes, and the location occupied by user U, etc.

Furthermore, if the location of user U's base is not included in the area expected to be flooded, the first notification information is, "The risk is relatively low, but please check the latest information." Note that, if user U's base is not included in the area expected to be flooded, the first notification information may further include information indicating the distance to the area expected to be flooded.

If the location of user U's base is included in a landslide warning area, the first notification information is "Risk of landslide." Note that if user U's base is not included in a landslide warning area, the notification information may further include information indicating the distance to the landslide warning area.

If the location of user U's base is not included in a landslide warning area and the surrounding environment is other than "applicable", the first notification information is "The risk is relatively low, but please check the latest information." Also, if the location of user U's base is not included in a landslide warning area and the surrounding environment is "applicable", the first notification information is "There is a risk of damage from flooding (floods, landslides, etc.)."

3.2.4. Text Correspondence Information Storage Unit 23
The text response information storage unit 23 stores text response information including, for each alert level, second notification information, which is information to be notified to the user U depending on the notification level set by the user U and the result of the risk check.

Figure 7 is a diagram showing an example of the wording correspondence information stored in the wording correspondence information storage unit 23 according to the embodiment. The wording correspondence information shown in Figure 7 is information in which second notification information is associated with "user settings" and "progress phase", etc.

"User setting" is the alert level set arbitrarily by user U, and is either "alert level 3" or "alert level 4." "Alert level 3" and "alert level 4" are each associated with "risk check OK" and "risk check NG." "Risk check OK" indicates that the result of the risk check is OK, and "Risk check NG" indicates that the result of the risk check is NG.

Here, assume that the text correspondence information is in the state shown in FIG. 7, the notification level set by user U is alert level 3, and the risk check is OK. In this case, when an alert level 3 alert is issued, information including the notification "Please check your actions in case of a disaster" and the disaster prevention TL (TimeLine) top "Check your actions in case of a disaster" is extracted as the second notification information by the processing unit 12; when an alert level 4 alert is issued, information including the notification "Are you safe? Please check your actions in case of a disaster" and the disaster prevention TL top "Check your actions in case of a disaster" is extracted; and when an alert level 5 alert is issued, information including the notification "Take actions to protect your life" and the disaster prevention TL top "Take actions to protect your life" is extracted as the second notification information by the processing unit 12.

Also, assume that the text correspondence information is in the state shown in FIG. 7, the notification level set by user U is alert level 3, and the risk check is NG. In this case, when an alert level 3 alert is issued, information including the notification "Are you in a dangerous place? Check what to do in case of a disaster" and the disaster prevention TL top "Are you in a dangerous place? Check what to do in case of a disaster" is extracted as the second notification information by the processing unit 12; when an alert level 4 alert is issued, information including the notification "Are you in a dangerous place? Check what to do in case of a disaster" and the disaster prevention TL top "Are you in a dangerous place? Check what to do in case of a disaster" is extracted as the second notification information by the processing unit 12; when an alert level 5 alert is issued, information including the notification "Take action to protect your life" and the disaster prevention TL top "Take action to protect your life" is extracted as the second notification information by the processing unit 12.

Also, assume that the text correspondence information is in the state shown in FIG. 7, the notification level set by user U is alert level 4, and the risk check is OK. In this case, when an alert level 4 alert is issued, information including the notification "Please check your actions in case of a disaster" and the disaster prevention TL top "Check your actions in case of a disaster" is extracted as second notification information by the processing unit 12, and when an alert level 5 alert is issued, information including the notification "Take action to protect your life" and the disaster prevention TL top "Take action to protect your life" is extracted as second notification information by the processing unit 12. Note that since the notification level is alert level 4, no information corresponding to an alert level 3 alert is specified.

Also, assume that the text correspondence information is in the state shown in FIG. 7, the notification level set by user U is alert level 4, and the risk check is NG. In this case, when an alert level 3 alert is issued, information including the disaster prevention TL top "Are you in a dangerous place? Check disaster prevention actions" is extracted as the second notification information by the processing unit 12; when an alert level 4 alert is issued, information including the notification "Everyone in a dangerous place evacuate. Check disaster prevention actions" and the disaster prevention TL top "Everyone in a dangerous place evacuate. Check disaster prevention actions" is extracted as the second notification information by the processing unit 12; and when an alert level 5 alert is issued, information including the notification "Take action to protect your life" and the disaster prevention TL top "Take action to protect your life" is extracted as the second notification information by the processing unit 12.

In the wording correspondence information shown in FIG. 7, the results are divided into two types, risk check OK and risk check NG, and second notification information is assigned to each of them, but the results of the risk check may be divided into three or more stages and second notification information may be assigned to each.

Also, the connection relationships between the processing units in the processing unit 12 are not limited to the connection relationships shown in FIG. 3, and may be other connection relationships.

[3.3.1. Acquisition unit 30]
The acquisition unit 30 acquires user information transmitted from the terminal device 2, disaster-related information transmitted from the disaster-related information providing device 3, evacuation information transmitted from the evacuation information providing device 4, and information transmitted from the area status information providing device 5. The communication unit 10 acquires, via the communication network 6 and the communication section 10, area status information to be displayed and traffic information transmitted from a traffic information providing device (not shown).

[3.3.1.1. Acquisition of user information]
The acquisition unit 30 acquires user information transmitted from the terminal device 2, and updates the user setting information stored in the user setting information storage unit 21 and the user information stored in the user information storage unit 20 based on the acquired user information.

The user information acquired from the terminal device 2 is information about the user U, and includes the above-mentioned user setting information set by the user U, location information of the user U, etc. The user setting information includes information on multiple attributes related to the user U. The multiple attributes related to the user U include, for example, the location of the base of the user U, attributes of the base of the user U, attributes of the user U, etc.

In order to obtain user information including user setting information from the terminal device 2 by the obtaining unit 30, the processing unit 12 transmits information of multiple screens from the providing unit 35 via the communication unit 10 and the communication network 6 to the terminal device 2, and causes the terminal device 2 to display a display screen including an input screen for obtaining user information. By operating the terminal device 2, the user U inputs various information into the input screen displayed on the terminal device 2, and causes the terminal device 2 to transmit the user information including the user setting information to the information providing device 1. As a result, the user information is obtained by the obtaining unit 30 of the processing unit 12.

Here, an example of a method for the processing unit 12 to acquire user setting information from the user U will be described in detail. The processing unit 12 acquires user setting information from the user U by displaying on the terminal device 2 information on various screens such as an item selection screen, a user environment input screen, an action start timing setting screen, a cohabitation information setting screen, a contact setting screen, and an evacuation destination editing screen. Note that the information on these screens may be information included in an application installed on the terminal device 2, and in this case, the screen information is not transmitted from the processing unit 12.

[3.3.1.1.1. Item selection screen, user environment input screen, risk check result screen]
FIG. 8 is a diagram showing an example of an item selection screen and a user environment input screen provided from the information providing device 1 according to the embodiment and displayed on the terminal device 2. As shown in FIG.

When the acquisition unit 30 receives a user information setting request from the terminal device 2 via the communication network 6 and the communication unit 10, in other words, when there is an initial setting request from the user U, the provision unit 35 transmits information for displaying the item selection screen 40 shown in FIG. 8(a) to the terminal device 2, and causes the terminal device 2 to display the item selection screen 40.

The item selection screen 40 is the first screen for creating a disaster prevention timeline for each user U, and displays multiple items arranged in a timeline format. In the example shown in FIG. 8(a), the item selection screen 40 includes an expected danger level check button 41a, an evacuation timing setting button 41b, a stockpile setting button 41c, a contact setting button 41d, and an evacuation destination setting button 41e. These buttons 41a, 41b, 41c, 41d, and 41e are selected by the user U by clicking or tapping using an operation unit (not shown) of the terminal device 2.

The expected danger level check button 41a is a UI (User Interface) button that causes the processing unit 12 to start an expected danger level check process for checking the danger level of the base of the user U. The evacuation timing setting button 41b is a UI button that causes the processing unit 12 to start an evacuation timing setting process for setting the evacuation timing of the user U.

The emergency supplies setting button 41c is a UI button for starting the emergency supplies setting process for setting emergency supplies for user U. The contacts setting button 41d is a UI button for causing the processing unit 12 to start the contacts setting process for setting the contacts that user U will contact. The evacuation destination setting button 41e is a UI button for causing the processing unit 12 to start the evacuation destination setting process for setting an evacuation destination for user U.

First, the expected risk check process will be described. When the user U selects the expected risk check button 41a on the item selection screen 40 shown in FIG. 8(a), the providing unit 35 transmits information for displaying the user environment input screen 42 shown in FIG. 8(b) to the terminal device 2, and causes the terminal device 2 to display the user environment input screen 42.

The user environment input screen 42 includes a map 43a including the location of the base, a text box 43b for inputting the location of the base, tabs 43c, 43d and radio buttons 43e, 43f, 43g for selecting the building attributes of the base, check boxes 43h, 43i for inputting the surrounding environment of the base, check boxes 43j, 43k, 43l, 43m for inputting the status of cohabitants, etc., and a check start button 43n.

By operating the terminal device 2, the user U can input the location (address) of the user U's base into the text box 43b. When the location of the user U's base is input into the text box 43b, the acquisition unit 30 acquires information on the input location. Based on the location information acquired by the acquisition unit 30, the provision unit 35 updates the map 43a to a map that includes the location of the user U's base.

Furthermore, by operating the terminal device 2, the user U can select "detached house" as the building attribute of the user U's base by selecting tab 43c, and can select "apartment building" as the building attribute of the user U's base by selecting tab 43d.

In the example shown in FIG. 8(b), tab 43c is selected and radio buttons 43e, 43f, and 43g are displayed on the terminal device 2. Radio button 43e is selected when user U's base is a one-story detached house, radio button 43f is selected when user U's base is a two-story detached house, and radio button 43g is selected when user U's base is a three-story or higher detached house.

When user U selects tab 43d, radio buttons for selecting which floor the room occupied by user U is on in the apartment building that is user U's base are displayed on the terminal device 2. Note that the radio buttons displayed in this case may be radio buttons 43e, 43f, and 43g.

Furthermore, the user U can set information about the surrounding environment, which is the environment around the user U's base, by operating the terminal device 2 and checking the corresponding check boxes 43h and 43i. The user U checks the check box 43h if there is a river near the user U's base, and the user U checks the check box 43i if there is a cliff near the user U's base.

In addition, user U can set information about cohabitants, such as housemates and pets, who live at user U's base by operating terminal device 2 and checking the corresponding check boxes among check boxes 43j, 43k, 43l, and 43m.

Check box 43j is checked by the user U if there are young children living with them, and check box 43k is checked by the user U if there are elderly people living with them. In addition, check box 43l is checked by the user U if there are people living with disabilities, and check box 43m is checked by the user U if there are pets living with them.

After the user U sets the necessary information on the user environment input screen 42, the user U operates the terminal device 2 to select the check start button 43n, and the information set on the user environment input screen 42 is transmitted from the terminal device 2 to the information providing device 1. As a result, the information set on the user environment input screen 42 is acquired by the acquisition unit 30 as user setting information.

After the information set in the user environment input screen 42 is acquired by the acquisition unit 30, the provision unit 35 transmits information for displaying a risk check result screen showing the result of the assumed risk check to the terminal device 2, and causes the terminal device 2 to display the risk check result screen. Note that the processing of the assumed risk check is performed by the determination unit 31 based on the information set in the user environment input screen 42, etc.

Figure 9 shows an example of a risk level check result screen and an action start timing setting screen provided by the information providing device 1 according to the embodiment and displayed on the terminal device 2. As shown in Figure 9 (a), the risk level check result screen 44 displayed on the terminal device 2 after the user U selects the check start button 43n shown in Figure 8 (b) includes a map 45a, a base location 45b, an estimated risk level 45c, a timing setting start button 45d, etc.

Map 45a is a map including the location of user U's base, with areas expected to be flooded and areas at risk of landslides highlighted. Base location 45b is information indicating the location of user U's base. Expected risk level 45c is information according to the degree of impact of the disaster on user U, and in the example shown in FIG. 9(a), includes information indicating the risk level on a hazard map.

In the example shown in FIG. 9(a), the degree of impact of flooding on user U is the flood depth rank code "3" shown in FIG. 6, and the degree of impact of landslides on user U is "1." Therefore, the character strings "Risk of flooding above the second floor (3 to 5 m)" and "Risk of landslides" are displayed as the expected risk level 45c. The expected risk level 45c is the first notification information, and is information extracted by the provision unit 35 from the expected risk level determination information stored in the expected risk level determination information storage unit 22.

The degree of impact of a landslide disaster on user U is indicated in two stages, with "1" indicating an impact and "0" indicating no impact, but it may be indicated in three or more stages. In this case, the expected risk level 45c may include, for example, "risk of landslide (0.5 to 3 m) above the first floor" or "risk of landslide (3 to 5 m) above the second floor."

In the wording correspondence information shown in FIG. 7, a risk check NG is assigned to user U when the risk is high (the impact of the disaster on user U is high) such that the location of the base is included in a flood-prone area or a landslide-prone area, and a risk check OK is assigned to user U otherwise.

[3.3.1.1.2. Action start timing setting screen]
After the user U checks the results of the risk check on the risk check result screen 44 shown in Figure 9 (a), he or she operates the terminal device 2 to select the timing setting start button 45d. The providing unit 35 then transmits information for displaying the action start timing setting screen 46 shown in Figure 9 (b) to the terminal device 2, and causes the terminal device 2 to display the action start timing setting screen 46.

As shown in FIG. 9(b), the action start timing setting screen 46 includes a suggested timing display area 47a, setting buttons 47b and 47c, etc. In the example shown in FIG. 9(b), the suggested timing display area 47a indicates alert level 3 as the timing when user U should start taking action in the event of a disaster. Note that "in the event of a disaster" includes the period during which a disaster is predicted to occur. The timing when user U should start taking action in the event of a disaster is determined by the determination unit 31 based on the results of the risk level check, etc.

The setting button 47b is a UI button for setting the timing to start the action to the time when alert level 3 is announced, and the setting button 47c is a UI button for setting the timing to start the action to the time when alert level 4 is announced. The user U operates the terminal device 2 to select either the setting button 47b or the setting button 47c, thereby setting the timing to start the action.

When the user U operates the terminal device 2 to select either the setting button 47b or the setting button 47c, notification level selection information, which is information about the selected button, is transmitted from the terminal device 2, and the notification level selection information transmitted from the terminal device 2 is acquired by the acquisition unit 30.

Based on the notification level selection information acquired by the acquisition unit 30, the providing unit 35 transmits information for displaying a timing setting confirmation screen according to the selection result by the user U to the terminal device 2, and causes the terminal device 2 to display the timing setting confirmation screen. FIG. 10 is a diagram showing an example of a timing setting confirmation screen and an action setting start screen provided from the information providing device 1 according to the embodiment and displayed on the terminal device 2.

The example shown in FIG. 10(a) shows a timing setting confirmation screen 48 that is displayed on the terminal device 2 when the user U selects the setting button 47b, i.e., when alert level 3 is selected as the timing for starting an action. The timing setting confirmation screen 48 includes a setting level information display area 49a, a disaster prevention timeline sample display area 49b, and a decision button 49c.

The set level information display area 49a shows information on the alert level selected by the user U as the timing for starting action. In the example shown in FIG. 10(a), the timing for starting action selected by the user U is the timing when alert level 3 is announced. The disaster prevention timeline sample display area 49b shows an example of disaster prevention timeline information displayed on the terminal device 2 based on information transmitted from the information providing device 1 when alert level 3 is announced.

If the user U has no problem with the setting level information displayed in the setting level information display area 49a on the timing setting confirmation screen 48, the user U selects the decision button 49c. When the user U operates the terminal device 2 to select the decision button 49c, decision information indicating that the decision button 49c has been selected is transmitted from the terminal device 2. When the acquisition unit 30 acquires the decision information transmitted from the terminal device 2, it associates the notification level corresponding to the setting button selected by the user U with the user ID of the user U as the setting level in the user setting information stored in the user setting information storage unit 21.

For example, when the setting button 47b is selected on the action start timing setting screen 46 shown in FIG. 9(b), the acquisition unit 30 associates "3" as the setting level corresponding to the selected button with the user ID of user U in the user setting information. When the setting button 47c is selected on the action start timing setting screen 46, the acquisition unit 30 associates "4" as the setting level corresponding to the selected button with the user ID of user U in the user setting information.

When the decision button 49c is selected, the providing unit 35 transmits information for displaying the action setting start screen 50 shown in FIG. 10(b) to the terminal device 2, and causes the terminal device 2 to display the action setting start screen 50. The action setting start screen 50 shown in FIG. 10(b) includes a stockpile setting start button 51, and by selecting the stockpile setting start button 51, the user U causes the terminal device 2 to display a cohabitation information setting screen for inputting information required to determine necessary stockpiles.

In this case, on the item selection screen 40, the user U can change the order of buttons 41b, 41c, 41d, and 41e by operating the terminal device 2, thereby changing the setting of the display order of the disaster prevention action information.

User U can also set information on multiple disaster prevention actions by selecting buttons 41b, 41c, 41d, and 41e to add specific details of the disaster prevention actions, but can also exclude information on disaster prevention actions shown on the disaster prevention timeline by not setting information on some disaster prevention actions.

In the default settings, the disaster prevention actions shown on the disaster prevention timeline are the actions of checking stockpiles, checking contact information, checking evacuation sites, and evacuating to evacuation sites, but user U can add new disaster prevention actions to the disaster prevention timeline. New disaster prevention actions include, for example, the actions of checking the news, checking the evacuation situation, checking and carrying necessary items that are items that need to be carried, etc.

The news confirmation action is the action of confirming information on damage or damage prediction information caused by a disaster in an area including the base of user U, and the action of confirming damage information or damage prediction information is, for example, confirmation of information obtained in real time from a website that provides news for the area including the base of user U. The evacuation status confirmation action is, for example, the action of confirming the evacuation status of people in the area including the base of user U, and for example, the action of confirming evacuation information notified from the evacuation information providing device 4.

[3.3.1.2. Acquisition of disaster-related information]
The acquisition unit 30 acquires the warning information transmitted from the disaster-related information providing device 3 via the communication network 6 and the communication unit 10. The disaster-related information is information related to disasters, and includes hazard map information, warning information, and weather forecast information. The hazard map information includes information on areas expected to be flooded and areas at risk of landslides. The warning information is information related to disaster warnings, and includes information on warning target areas that are areas subject to warnings, and information on the warning level for each warning target area. The weather forecast information includes information indicating the predicted amount of rainfall and wind speed per hour for each area.

[3.3.1.3. Acquiring evacuation information]
The acquisition unit 30 acquires evacuation information transmitted from the evacuation information providing device 4 via the communication network 6 and the communication unit 10. The evacuation information includes information regarding evacuation in response to a disaster and information indicating the evacuation status of each of the multiple users U. The acquisition unit 30 updates the evacuation-related information stored in the evacuation-related information storage unit 24 based on the acquired evacuation information.

3.3.1.4. Obtaining Area Status Information
The acquisition unit 30 acquires area status information transmitted from the area status information providing device 5 via the communication network 6 and the communication unit 10. The area status information is information indicating an area status including each movement route between the base of a plurality of users U and each evacuation site, and includes information such as locations of road closures, locations that have become dangerous or are predicted to become dangerous due to a disaster or the like, locations where accidents have occurred, locations where there is congestion, and the like.

[3.3.1.5. Obtaining Traffic Information]
The acquisition unit 30 acquires traffic information transmitted from a traffic information providing device (not shown) via the communication network 6 and the communication unit 10. The traffic information includes information indicating the state of transportation from the location of the user U to the base (e.g., living base) or evacuation site of the user U. The information indicating the state of transportation includes information on the current operation schedules of trains, buses, airplanes, etc., information indicating the availability of taxis, information indicating the location of taxis, etc.

[3.3.2. Judgment unit 31]
The determination unit 31 determines the degree of impact of a disaster on the user U based on the disaster-related information and user information acquired by the acquisition unit 30. The disaster-related information is information related to a disaster, and includes a hazard map The user information includes information on a plurality of attributes relating to the user U.

Hazard map information includes information on areas expected to be flooded and areas at risk of landslides. Information on areas expected to be flooded includes information indicating the location of the areas expected to be flooded and the expected flood depth, and the expected flood depth is the expected depth of flooding. Information on areas at risk of landslides includes information indicating the location of the areas at risk of landslides.

Weather forecast information is information that indicates the weather conditions for each region estimated from the weather conditions, and includes, for example, information that indicates the predicted amount of rainfall and wind speed per hour for each region. Warning information is information about disaster warnings, and includes information about the regions that are subject to each alert level for each alert level.

Attributes related to user U include, for example, the location of user U's base, attributes of user U's base, attributes of the surrounding area of user U's base, attributes of user U, attributes of user U's housemates, attributes of user U's pets (including whether or not they exist), etc. Attributes of the surrounding area of user U's base include, for example, information on whether or not there is a river or cliff near user U's base.

The determination unit 31 determines the degree of impact of a disaster on the user U that is expected in the event of a disaster, based on the hazard map information and the user information. This degree of impact is the degree of risk expected on the hazard map information, and may be referred to as the first degree of impact hereinafter.

The determination unit 31 determines whether or not the base of user U is included in the expected flooding area, for example, based on information about the expected flooding area and the location of the base of user U. If the determination unit 31 determines that the base of user U is included in the expected flooding area, it determines that the first degree of impact is high, and if not, it determines that the first degree of impact is low.

In addition, when the determination unit 31 determines that the base of user U is included in an area expected to be flooded, the determination unit 31 can also determine the first degree of impact based on the expected flood depth at the location of user U's base and the building attributes and occupied location of user U's base.

For example, if the expected flood depth at the location of user U's base is a maximum of 3 to 5 m, and the building attributes of user U's base are a two-story detached house, the risk is determined to be high. Also, if the expected flood depth at the location of user U's base is a maximum of 3 to 5 m, the building attributes of user U's base are a 10-story apartment building, and user U's occupied location is on the fifth floor, the risk is determined to be lower than when the building attributes of user U's base are a two-story detached house.

The determination unit 31 also determines whether or not the base of user U is included in a landslide disaster warning area, for example, based on information about the landslide disaster warning area and the location of the base of user U. If the determination unit 31 determines that the base of user U is included in a landslide disaster warning area, it determines that the first degree of impact is high, and if not, it determines that the first degree of impact is low.

In addition, if the determination unit 31 determines that the base of user U is included in a landslide disaster warning area, the determination unit 31 can also determine the first degree of impact based on the building attributes and occupied location of the base of user U.

For example, the determination unit 31 determines that the first degree of influence is high when the building attribute of the user U's base is a two-story detached wooden house, and determines that the first degree of influence is low when the building attribute of the user U's base is a 10-story apartment building with a reinforced concrete structure and the user U's occupied location is on the fifth floor, compared to when the building attribute of the user U's base is a two-story detached wooden house.

Furthermore, in addition to information on the location of the landslide disaster warning area, information such as the expected sediment inflow speed, the expected sediment inflow volume, or the expected sediment inflow depth may be included. When the determination unit 31 determines that the base of user U is included in the landslide disaster warning area, it determines the degree of impact on user U's base based on the expected sediment inflow speed, the expected sediment inflow volume, or the expected sediment inflow depth at user U's base and the building attributes and occupied position of user U's base, and determines the determined degree of impact as the first degree of impact. The degree of impact on user U's base is higher the greater the amount and depth of sediment inflow to user U's base, for example, based on the expected sediment inflow speed, the expected sediment inflow volume, or the expected sediment inflow depth.

The determination unit 31 also determines the degree of impact of the disaster on the user U based on the weather forecast information and user information acquired by the acquisition unit 30. This degree of impact is the degree of impact on the disaster predicted in real time based on the weather forecast information, and may be referred to as the second degree of impact hereinafter.

The determination unit 31 determines the predicted presence or absence of flooding, the depth of flooding, and the presence or absence of landslide at the location of the user U's base based on the weather forecast information acquired by the acquisition unit 30. The determination unit 31 can determine the second degree of impact based on the predicted presence or absence of flooding, the depth of flooding, and the presence or absence of landslide at the location of the user U's base.

For example, if there is no predicted flooding at the location of user U's base, the determination unit 31 determines that the second degree of impact is low, and if there is predicted flooding at the location of user U's base, the determination unit 31 determines that the second degree of impact is high. Furthermore, the greater the predicted flood depth at the location of user U's base, the higher the determination unit 31 can determine the second degree of impact.

The determination unit 31 determines that the second degree of impact is low if there is no predicted inflow of sediment at the location of the user U's base, and determines that the second degree of impact is high if there is flooding with sediment at the location of the user U's base. The determination unit 31 can determine that the second degree of impact is higher the greater the amount of sediment predicted to flow into the location of the user U's base and the greater the depth of the sediment inflow.

The determination unit 31 can also determine the degree of impact of the disaster on the user U based on the warning information and user information acquired by the acquisition unit 30. This degree of impact is the degree of impact of the disaster on the user U in a state of an alert level indicated in the warning information for an area including the location of the base of the user U or an alert level one or two levels higher than the alert level indicated in the warning information, and may be hereinafter referred to as a third degree of impact.

For example, when the alert level indicated by the warning information is one level higher than the alert level of the area including the location of user U's base, if the building attributes of user U's base are a 10-story apartment building with a reinforced concrete structure and user U's location is on the fifth floor, the determination unit 31 increases the third degree of influence compared to when the building attributes of user U's base are a two-story detached wooden house.

Furthermore, the determination unit 31 can determine the first degree of influence, the second degree of influence, and the third degree of influence based on the attributes of user U, the attributes of user U's housemates, the attributes of user U's pets, the attributes of the surroundings of user U's base, and the like, in addition to or instead of the building attributes and occupied location of user U's base. Hereinafter, when the first degree of influence, the second degree of influence, and the third degree of influence are not individually indicated, they may be simply referred to as the degree of influence. The attributes of the surroundings of user U's base are, for example, attributes indicating whether or not there is a river or cliff near user U's base.

For example, if the user U is physically disabled, the determination unit 31 may determine a higher degree of impact compared to when the user U is not physically disabled, or may determine a higher degree of impact if the user U is ill compared to when the user U is not ill.

In addition, the determination unit 31 increases the degree of influence when the user U has cohabitants such as young children or elderly people compared to when the user U does not have cohabitants such as young children or elderly people, and increases the degree of influence when the user U has a pet compared to when the user U does not have a pet. In addition, the determination unit 31 increases the degree of influence the more cohabitants such as young children or elderly people there are, and increases the degree of influence the more pets there are.

In addition, when there is a river or a cliff near the base of user U, the determination unit 31 increases the degree of influence compared to when there is no river or cliff near the base of user U. In addition, when there is a river or a cliff near the base of user U, the determination unit 31 can also increase the degree of influence the closer the distance from the base of user U to the river or cliff.

The determination unit 31 also determines the current or future degree of congestion at the evacuation site pre-set for each of the multiple users U. For example, the determination unit 31 determines the current or future degree of congestion at the evacuation site pre-set for each of the multiple users U based on the evacuation information acquired by the acquisition unit 30. The evacuation site pre-set for the user U is the evacuation site set on the evacuation destination editing screen 62 shown in FIG. 13(b). The degree of congestion is, for example, the ratio of people evacuating to the evacuation site to the capacity of the evacuation site.

The determination unit 31 can also determine the current or future congestion level of the evacuation site pre-set for each user U based on location information indicating the location of each user U included in the user information acquired by the acquisition unit 30. In this case, the determination unit 31 determines the current congestion level of the evacuation site based on the location of the user U, and determines the future congestion level of the evacuation site based on the location of the user U and the location and movement status of the user U.

The determination unit 31 can also determine the future degree of congestion at the evacuation site based on the above-mentioned degree of influence in addition to the location of the user U. The determination unit 31 can also determine the future degree of congestion at the evacuation site based on changes in the alert level in addition to the location of the user U.

3.3.3. Determination unit 32
The determination unit 32 determines information to be provided, which is information regarding evacuation suited to a user U before evacuation, for a user U among a plurality of users U, based on the evacuation information and user information acquired by the acquisition unit 30. For example, when an evacuation location for the user U is not set in the user-related information, or when the congestion degree of the evacuation location for the user U set in the user-related information and determined by the determination unit 31 is equal to or greater than a threshold, the determination unit 32 determines information to be provided, which is information regarding evacuation suited to the user U before evacuation. Note that the timing of determination of the information to be provided by the determination unit 32 is not limited to such an example.

Information regarding evacuation in the event of a disaster includes, for example, information regarding evacuation sites and information regarding candidate evacuation routes to the evacuation sites. Information regarding evacuation sites includes information indicating the location, capacity, and area of the evacuation site. Information regarding candidate evacuation routes to the evacuation sites is, for example, information regarding multiple travel routes between the location of each user U's base and each evacuation site.

The information to be provided determined by the determination unit 32 includes, for example, information indicating the evacuation location of the user U, the evacuation route which is the route to travel to the evacuation location, and the timing of evacuation to the evacuation location.

For example, the determination unit 32 judges the current or future congestion level of each evacuation site based on the evacuation information. Then, the determination unit 32 determines the evacuation site for user U, the travel route to the evacuation site, and the timing of evacuation to the evacuation site based on the location of user U's base, the attributes of user U, multiple travel routes to each evacuation site (candidate evacuation routes), the current or future congestion status of each evacuation site, etc.

For example, the determination unit 32 determines, as the evacuation site for user U, the evacuation site for which the total value obtained by weighting the values according to the attributes of user U, the length of the travel route, the degree of congestion at the evacuation site, and the like is the smallest. Furthermore, based on the state of the area including the multiple travel routes to the determined evacuation site, the determination unit 32 determines, as the evacuation route, a travel route among the multiple travel routes to the evacuation site that avoids places that have become dangerous or are predicted to become dangerous due to a disaster or the like.

The determination unit 32 also determines the timing of evacuation as the timing when the total value obtained by weighting the values according to the attributes of the user U, the length of the travel route, the degree of congestion at the evacuation site, the value according to the alert level, and the like, exceeds a preset threshold value. The determination unit 32 then determines information to be provided to the user U that includes information indicating the determined evacuation site, evacuation route, and evacuation timing.

The value according to the attributes of user U is, for example, a value calculated according to the age, sex, physical condition, etc. of user U. In this way, the determination unit 32 determines information including information regarding evacuation according to the attributes of user U as information regarding evacuation according to user U as information to be provided. Note that the method of determining the evacuation location of user U, the travel route to the evacuation location, and the timing of evacuation to the evacuation location are not limited to the above-mentioned examples.

The determination unit 32 can also determine, as the information to be provided to the user U before evacuation, information further including information indicating the evacuation means of the user U before evacuation. For example, when the evacuation site is far from the base location of the user U, the determination unit 32 determines, as the information to be provided to the user U before evacuation, information further including information indicating that a taxi is a desirable means of transportation. Furthermore, when the travel route from the base location of the user U to the evacuation site is a narrow road, the determination unit 32 determines, as the information to be provided to the user U before evacuation, information further including information indicating that walking is a desirable means of transportation.

The determination unit 32 can also determine the evacuation means of the user U before evacuation as the means of transportation to be proposed to the user U before evacuation, based on the attributes of the user U before evacuation. For example, the determination unit 32 determines a taxi as the means of transportation when the user U is elderly or physically disabled. The determination unit 32 can also determine a taxi as the means of transportation when a value according to the attributes of the user U is equal to or greater than a threshold, and not determine the means of transportation when the value according to the attributes of the user U is less than the threshold. The value according to the attributes of the user U is a value calculated according to, for example, the age, physical condition, etc. of the user U.

The determination unit 32 also changes the evacuation location and evacuation route of at least one of the user U before evacuation and the user U during evacuation, based on at least one of the area state information acquired by the acquisition unit 30 and the congestion degree determination result by the determination unit 31. In this way, the determination unit 32 can determine the evacuation location and evacuation route of the user U depending on the evacuation situation of the other users U.

For example, when the current or future congestion level of an evacuation site determined as an evacuation site for user U before evacuation or user U during evacuation is equal to or greater than a threshold value, the determination unit 32 changes the evacuation site for user U before evacuation or user U during evacuation to a site different from the previously set evacuation site, and also changes the evacuation route. The method of determining the new evacuation site and evacuation route is the same as the method of determining the evacuation site and evacuation route before the change.

Furthermore, the determination unit 32 determines whether the evacuation route set for the user U as an evacuation route to an evacuation site for the user U before evacuation or during evacuation is difficult or impassable, based on the area state information acquired by the acquisition unit 30. If the determination unit 32 determines that the evacuation route set for the user U is difficult or impassable, it can determine, as the changed travel route for the user U, a travel route that is easy to pass and has the shortest distance to the evacuation site, based on the ease of passing among multiple travel routes to the evacuation site and the distance to the evacuation site, etc. Note that being unpassable includes being dangerous.

The determination unit 32 can also extract users U who are away from the evacuation target area from among the multiple users U based on the location information acquired by the acquisition unit 30, and determine an action to be proposed to the extracted users U.

For example, the determination unit 32 determines whether it is difficult to travel to the evacuation site by public transport and whether the congestion level of the evacuation site is equal to or higher than a threshold based on information on the state of public transport and information on the congestion level of the evacuation site set as the evacuation site for the user U. If the determination unit 32 determines that it is difficult to travel to the evacuation site by public transport or that the congestion level of the evacuation site is equal to or higher than a threshold, the determination unit 32 determines that the action proposed to the user U, who is far from the evacuation target area, is to stay in a place away from the evacuation target area instead of traveling to the base or to the set evacuation site. Note that the information on the state of public transport is included in the traffic information acquired by the acquisition unit 30, and the information on the congestion level of the evacuation site is information determined by the determination unit 31.

In addition, when the decision unit 32 determines that it is easy to travel to the evacuation site by public transportation or that the congestion level of the evacuation site is less than a threshold, it suggests that the user U, who is far from the evacuation target area, travel to the evacuation site that has been set. In this case, the decision unit 32 can determine the travel route and travel timing of the user U, who is far from the evacuation target area, and determine information including the determined travel route and travel timing as information on the proposed action.

The timing at which the determination unit 32 determines information regarding evacuation according to the user U before evacuation may be, but is not limited to, the timing at which an evacuation information request is made, the timing at which the alert level changes, the timing at which the alert level becomes the level set by the user U, or the timing at which the evacuation destination confirmation button 71h described below is selected.

In addition, before alert level 1 is announced, the determination unit 32 can also determine the evacuation site, evacuation route, and evacuation timing for user U based on, for example, information on the degree of congestion at evacuation sites during past disasters and area status information.

[3.3.4. Specification part 33]
The identification unit 33 identifies one or more disaster prevention actions according to the user U and the level of the warning from among the plurality of disaster prevention actions based on the warning information and the user information acquired by the acquisition unit 30. The disaster prevention actions include, for example, checking stockpiles, checking contact information, checking evacuation shelters, and evacuating to evacuation shelters.

The user setting information stored in the user setting information storage unit 21 includes information indicating the types of disaster prevention actions during normal times and the types of disaster prevention actions corresponding to each alert level, and the identification unit 33 can identify disaster prevention actions during normal times, disaster prevention actions at alert level 3, disaster prevention actions at alert level 4, disaster prevention actions at alert level 5, etc. based on the user setting information and disaster-related information, etc.

For example, if the location of user U's base is included in an area of alert level 3, the identification unit 33 can identify disaster prevention actions for alert level 3, and if the location of user U's base is included in an area of alert level 4, the identification unit 33 can identify disaster prevention actions for alert level 4.

The user setting information includes information indicating the order of disaster prevention actions at normal times, alert level 3, alert level 4, and alert level 5, and the identification unit 33 identifies the order of disaster prevention actions to be shown to user U based on the user setting information.

In addition, the identification unit 33 can also identify one or more disaster prevention actions corresponding to the user U and the alert level from among multiple disaster prevention actions based on the rate of change of the alert level and the attributes of the user U, instead of the type of disaster prevention action previously set in the user setting information.

For example, the identification unit 33 can identify one or more disaster prevention actions according to the attributes and alert level of the user U based on the user information stored in the user information storage unit 20. The attributes of the user U are, for example, the gender, age, interests, family structure, and occupation of the user U. For example, even for the same alert level, the identification unit 33 can identify different disaster prevention actions depending on the gender of the user U. In addition, the identification unit 33 can change the combination of the identified alert level and disaster prevention action according to a score obtained by weighting and adding values corresponding to each of the multiple attributes of the user U.

The identification unit 33 can also identify disaster prevention actions associated with the alert level set in the user setting information as disaster prevention actions at an alert level lower than the associated alert level, the faster the rate of change of the alert level. For example, if the time interval between the announcement of alert level 1 and the announcement of alert level 2 is equal to or less than a threshold, the identification unit 33 can identify disaster prevention actions associated with alert level 3 in the user setting information as disaster prevention actions to be notified at the time alert level 2 is announced.

The identification unit 33 can also identify a confirmation action that is frequently confirmed by the user U among multiple confirmation actions, which are a type of disaster prevention action, as a disaster prevention action for which the user U should be notified at an alert level lower than the alert level set in the user setting information. For example, if a confirmation action associated with alert level 3 is frequently confirmed, the identification unit 33 can identify such a confirmation action as a disaster prevention action for which the user U should be notified at alert level 2.

The identification unit 33 can also narrow down and identify disaster prevention actions to be identified from among multiple disaster prevention actions according to the attributes of the user U. For example, the identification unit 33 can narrow down disaster prevention actions to be identified from among multiple disaster prevention actions according to the attributes of the user U.

[3.3.5. Generation unit 34]
The generation unit 34 generates a stockpile list, which is a list of stockpiles necessary for the user U, based on the user information acquired by the acquisition unit 30.

For example, the generation unit 34 generates a list of supplies necessary for the user U and his/her housemates based on the user U's age, sex, number of housemates, age, sex, etc. The generation unit 34 also generates a list of supplies necessary for pets based on the number, type, breed name, etc. of pets kept by the user U.

[3.3.6. Providing Department 35]
The providing unit 35 transmits information on the alert level, disaster prevention information, information according to the degree of impact determined by the determining unit 31, information on the stockpile list, and the like to the terminal device 2 of the user U as provided information. The provision unit 35 provides the provided information to the user U. The provision unit 35 also transmits, to the terminal device of the user U, suggested information including information on the action (action suggested to the user U) determined by the determination unit 32. 2 to provide the proposal information to the user U.

When a request to send disaster prevention information from the user U is received by the communication unit 10 or when the alert level reaches a set level, the providing unit 35 provides the disaster prevention information to the user U as provided information. The disaster prevention information includes information on one or more disaster prevention actions identified by the identifying unit 33.

For example, if the providing unit 35 receives a request to send disaster prevention information when no warning indicating an alert level has been issued in the area including the location of the user U's base, the providing unit 35 provides the user U with disaster prevention information including information on disaster prevention actions that the user U should normally (under normal circumstances) as provided information.

Figure 15 is a diagram showing an example of a disaster prevention screen including provided information displayed on the terminal device 2 according to the embodiment. The disaster prevention screen 68 shown in Figure 15 includes warning-related information 69 and disaster prevention timeline information 70 that are provided to the user U and displayed on the terminal device 2 when there is no warning at or above the alert level.

The alert-related information 69 is text information including "There are no alerts of alert level 3 (or higher)" and "Updated at 10:10 on September 19th," and indicates that no alert level has been announced for the area including the location of user U's base.

The disaster prevention timeline information 70 is information on the disaster prevention timeline, and includes a normal time tag 71a, an expected danger level confirmation button 71b, an evacuation timing confirmation button 71c, an alert level 3 o'clock tag 71d, a stockpile confirmation button 71e, a contact confirmation button 71f, an alert level 4 o'clock tag 71g, an evacuation destination confirmation button 71h, and a precautions confirmation button 71i.

The expected danger confirmation button 71b, evacuation timing confirmation button 71c, stockpile confirmation button 71e, contact confirmation button 71f, evacuation destination confirmation button 71h, and precautions confirmation button 71i are information on the disaster prevention actions of the user U, and are displayed in timeline format in the order in which the user U confirms them.

In the disaster prevention timeline information 70 shown in FIG. 15, the expected danger confirmation button 71b and the evacuation timing confirmation button 71c are highlighted as information on disaster prevention actions that are preferable for the user U to take during normal times when no alerts of alert level 3 or higher have been issued in the area including the location of the user U's base, and the normal times tag 71a, which indicates that it is normal times, is also highlighted. Note that the highlighting is performed, for example, by coloring in red, but is not limited to this example.

The expected danger confirmation button 71b is a UI button for displaying the results of the expected danger check determined by the determination unit 31 on the terminal device 2. For example, when the expected danger confirmation button 71b is selected by the user U, the provision unit 35 causes the terminal device 2 to display the danger check result screen 44 shown in FIG. 9(a). This allows the user U to confirm the danger level, i.e., the degree of impact of the disaster on the user U. Note that in this case, the danger check result screen 44 includes a back button instead of the timing setting start button 45d. Furthermore, during normal times, the expected danger level 45c included in the danger check result screen 44 is an example of information corresponding to the degree of impact, and is information corresponding to the first degree of impact.

The evacuation timing confirmation button 71c is a UI button for displaying on the terminal device 2 information on the setting level, which is the alert level that the user U has set as the notification level based on the results of the expected danger check determined by the determination unit 31. For example, when the evacuation timing confirmation button 71c is selected by the user U, the provision unit 35 causes the terminal device 2 to display information on the setting level, for example, at a timing when the setting level included in the user setting information stored in the user setting information storage unit 21 matches the alert level.

The notification level may be automatically determined as the set level based on the alert level proposed by the determination unit 31 based on the result of the assumed danger check determined by the determination unit 31. In this case, the determination unit 31 adds the determined set level to the user setting information stored in the user setting information storage unit 21.

The disaster prevention timeline information 70 also includes an alert level 3 o'clock tag 71d, a stockpile check button 71e, a contact check button 71f, an alert level 4 o'clock tag 71g, an evacuation destination check button 71h, and a precautions check button 71i, which are not highlighted under normal circumstances and are highlighted when there is an alert of alert level 3 or higher, as described below.

The Check Stockpiles button 71e and Check Contacts button 71f are displayed below the Alert Level 3 o'clock tag 71d and above the Alert Level 4 o'clock tag 71g, so that user U knows that they are set to check stockpiles and check contacts when Alert Level 3 is announced.

The evacuation destination confirmation button 71h and the precautions confirmation button 71i are displayed below the alert level 4 tag 71g, which allows the user U to understand that they are set to confirm evacuation destinations and precautions when alert level 4 is announced.

The Check Stockpiles button 71e is a button for checking stockpiles, which is one of the disaster prevention actions, and the user U can select the Check Stockpiles button 71e by operating the terminal device 2. When the Check Stockpiles button 71e is selected, the providing unit 35 provides the user U with information on the stockpiles list generated by the generating unit 34.

The information on the stockpile list is provided to the user U, for example, by displaying information including the first stockpile list display area 55b and the second stockpile list display area 55c on the stockpile setting confirmation screen 54 shown in FIG. 11(b) on the terminal device 2.

The contact confirmation button 71f is a button for confirming contact, which is one of the disaster prevention actions, and the user U can select the contact confirmation button 71f by operating the terminal device 2. When the contact confirmation button 71f is selected, the providing unit 35 provides the user U with the contact information set by the user U and included in the user setting information. The contact information is provided to the user U, for example, by displaying information including the contact information display area 59a of the contact confirmation screen 58 shown in FIG. 12(b) on the terminal device 2.

The evacuation destination confirmation button 71h is a button for confirming an evacuation destination, which is one of the disaster prevention actions, and the user U can select the evacuation destination confirmation button 71h by operating the terminal device 2. When the evacuation destination confirmation button 71h is selected, the providing unit 35 provides the user U with evacuation destination information set by the user U and included in the user setting information. The evacuation destination information is provided to the user U, for example, by displaying information including the map 65a of the evacuation destination setting screen 64 shown in FIG. 14(a) on the terminal device 2.

The precaution confirmation button 71i is a button for confirming precautions to take when evacuating, which is one of the disaster prevention actions, and the user U can select the precaution confirmation button 71i by operating the terminal device 2. When the precaution confirmation button 71i is selected, the providing unit 35 provides the precaution information to the user U. The precaution information includes information indicating precautions to take when evacuating and information indicating precautions to take when it is impossible to reach an evacuation site.

In the above example, the disaster prevention actions proposed during normal times are checking the results of the expected danger check and checking the timing of evacuation, while at alert level 3 the actions of checking stockpiles and contact information are proposed, and at alert level 4 the actions of checking the evacuation destination and points of caution are proposed, but the proposed disaster prevention actions, the proposed timing, and the proposed order are not limited to these examples.

For example, the proposed disaster prevention actions, the timing of the proposal, and the order of the proposal are changed according to settings made by user U. Note that the proposed disaster prevention actions, the timing of the proposal, and the order of the proposal can also be automatically set by the determination unit 31 according to the attributes of user U, the attributes of user U's base, the type of disaster, and the progress leading up to the disaster, etc.

In addition, during normal times, the alert level 3 o'clock tag 71d, stockpile check button 71e, contact check button 71f, alert level 4 o'clock tag 71g, evacuation destination check button 71h, and precautions check button 71i do not have to be included in the disaster prevention timeline information 70. Also, during normal times, the alert level 3 o'clock tag 71d, stockpile check button 71e, contact check button 71f, alert level 4 o'clock tag 71g, evacuation destination check button 71h, and precautions check button 71i may be arranged in a smaller size than that shown in FIG. 15.

In this way, during normal times, the provision unit 35 can suggest to the user U the action of checking stockpiles and the action of checking contact information as disaster prevention actions, thereby enabling the user U to take appropriate disaster prevention actions.

Next, a case will be described where the set level is alert level 3 and the location of user U's base is included in the area where an alert level 3 warning has been issued. When the location of user U's base is included in the area where the alert level has been announced, the providing unit 35 notifies user U of warning notification information, which is information on the alert level of the area including the location of user U's base, as provided information based on the alert information acquired by the acquiring unit 30.

In addition, the providing unit 35 notifies the user U of disaster prevention alert information when the location of the user U's base is included in the area where the alert level alert has been issued, and further provides the disaster prevention alert information to the user U as provided information when the location of the user U's base is included in the area where the alert level alert has been issued and the alert level is the level set by the user U.

Figure 16 is a diagram showing another example of a display screen including provided information and a disaster prevention screen displayed on a terminal device 2 according to an embodiment. A display screen 72 shown in Figure 16 (a) includes warning notification information 73 and disaster prevention notification information 74 that are provided to user U and displayed on the terminal device 2 when alert level 3 is announced and the setting level of user U is alert level 3. In the example shown in Figure 16 (a), the warning notification information 73 and disaster prevention notification information 74 are displayed as a pop-up on the top screen of the terminal device 2, thereby allowing user U to easily understand the warning notification information 73 and disaster prevention notification information 74.

The warning notification information 73 shown in FIG. 16(a) is text information including "[Equivalent to Alert Level 3] Now" and "Risk of landslides rising in City B, A Prefecture. Check risky areas on the map (announced at 13:00)," and is provided to user U when the area in which a warning indicating the alert level has been issued is "City B, A Prefecture," and the location of user U's base is "City B, A Prefecture."

The disaster prevention notification information 74 shown in FIG. 16(a) is text information including "[Disaster prevention timeline] Now," "Alert level 3 (or equivalent) announced for the area around your home," and "Are you in a dangerous location? Please check your actions in the event of a disaster."

The providing unit 35 determines text information of "Alert level 3 (or equivalent) has been announced around the home" based on the alert information acquired by the acquiring unit 30. The providing unit 35 also determines text information of "Are you in a dangerous location? Please check your actions in the event of a disaster" included in the disaster prevention alert information 74 based on the alert information, the danger level (degree of impact of the disaster on the user U) determined by the determining unit 31, and the text response information stored in the text response information storage unit 23.

The text information "Are you in a dangerous location? Please check your actions in the event of a disaster" shown in FIG. 16(a) is notification information extracted from the second notification information corresponding to the case where alert level 3, which is the setting level of user U, is announced and the risk check at user U's base is NG. Disaster prevention alert information 74 may include information corresponding to the second impact degree or information corresponding to the third impact degree instead of or in addition to the information corresponding to the first impact degree.

The user U can select disaster prevention alert information 74 included in the display screen 72 by clicking or tapping using an operation unit (not shown) of the terminal device 2. When the user U selects the disaster prevention alert information 74, the providing unit 35 provides the disaster prevention information to the user U by transmitting information to the terminal device 2 for displaying a disaster prevention screen 75 shown in FIG. 16(b). The disaster prevention screen 75 shown in FIG. 16(b) includes disaster prevention information including warning-related information 69 and disaster prevention timeline information 70.

The warning-related information 69 shown in FIG. 16(b) includes warning information 69a indicating that alert level 3 has been announced, and notification information 69b which is information according to the degree of impact of the disaster on user U. The notification information 69b shown in FIG. 16(b) is information at the top of the disaster prevention TL extracted from the second notification information corresponding to the case where alert level 3 has been announced and the risk check at user U's base is NG, and is text information stating "Are you in a dangerous location? Please check your actions in the event of a disaster." The information at the top of the disaster prevention TL is an example of information indicating the degree of necessity for evacuation by user U. Furthermore, the notification information 69b is information according to the first degree of impact.

In the disaster prevention timeline information 70 shown in FIG. 16(b), at alert level 3, when an alert level 3 warning has been issued in the area including the location of the user U's base, the stockpile check button 71e and the contact check button 71f are highlighted as information on disaster prevention actions that the user U should preferably take, and the alert level 3 tag 71d, which indicates that it is alert level 3, is also highlighted. Note that the highlighting is performed, for example, by coloring in red, but is not limited to this example.

In this way, when an alert level 3 warning is issued, the provision unit 35 can suggest to the user U the actions of checking stockpiles and checking contact information as disaster prevention actions, thereby enabling the user U to take appropriate disaster prevention actions.

Next, a case will be described where the set level is alert level 3 and the location of user U's base is included in an area where an alert of alert level 4 has been issued. When alert level changes from 3 to 4, the providing unit 35 notifies user U of alert-related information and disaster prevention timeline information as provided information.

Figure 17 is a diagram showing yet another example of a display screen including provided information and a disaster prevention screen displayed on a terminal device 2 according to an embodiment. A display screen 76 shown in Figure 17 (a) includes warning-related information 69 and disaster prevention timeline information 70 that are provided to user U and displayed on the terminal device 2 when the setting level of user U is alert level 3 and the alert level of the area including the location of user U's base changes from 3 to 4.

The alert-related information 69 shown in FIG. 17(a) includes alert information 69a indicating that alert level 4 has been announced, and notification information 69b which is information according to the degree of impact of the disaster on user U. The notification information 69b shown in FIG. 17(a) is information on the disaster prevention TL top extracted from the second notification information corresponding to the case where alert level 4 has been announced and the risk check at user U's base is NG, and is text information stating "Are you safe? Please check your actions in the event of a disaster."

In the disaster prevention timeline information 70 shown in FIG. 17(a), when an alert level 4 warning is issued in the area including the location of the base of the user U, the evacuation destination confirmation button 71h and the caution confirmation button 71i are highlighted as information on disaster prevention actions that the user U should preferably take at alert level 4, and the alert level 4 tag 71g indicating that it is alert level 4 is highlighted. The highlighting is performed, for example, by coloring in red, but is not limited to this example. For example, the highlighting may be performed in accordance with the disaster alert colors designated by the Cabinet Office or the Japan Meteorological Agency, such as purple for alert level 4 and black for alert level 5. The alert level 4 tag 71g also includes text information saying "Evacuation order issued", and such text information allows the user U to understand the degree of necessity for evacuation.

In this way, when an alert level 4 warning is issued, the providing unit 35 can suggest to the user U disaster prevention actions, such as checking an evacuation destination and checking points to be aware of when evacuating, thereby enabling the user U to take appropriate disaster prevention actions.

Next, a case will be described where the location of user U's base is included in an area where an alert level 5 alert has been issued. When alert level changes from 4 to 5, the providing unit 35 notifies user U of alert-related information 69 and disaster prevention timeline information 70 as provided information.

The display screen 77 shown in FIG. 17(b) includes warning-related information 69 and disaster prevention timeline information 70 that are provided to user U and displayed on the terminal device 2 when the alert level for the area including the location of user U's base rises from 4 to 5.

The alert-related information 69 shown in FIG. 17(b) includes alert information 69a indicating that alert level 5 has been announced, and notification information 69b which is information according to the degree of impact of the disaster on user U. The notification information 69b shown in FIG. 17(b) is information on the disaster prevention TL top extracted from the second notification information corresponding to the case where alert level 5 has been announced and the risk check at user U's base is NG, and is text information stating "Take action to protect your life." Note that the above-mentioned notification information 69b may include information according to the second degree of impact or information according to the third degree of impact instead of or in addition to the information according to the first degree of impact.

In the disaster prevention timeline information 70 shown in FIG. 17(b), at alert level 5, when an alert level 5 warning has been issued in the area including the location of the user U's base, a caution confirmation button 71i is highlighted as information on disaster prevention actions that the user U should preferably take, and an alert level 5 tag 71j indicating that it is alert level 5 is also highlighted. Note that the highlighting is performed, for example, by coloring in red, but is not limited to this example.

In this way, when an alert level 5 warning is issued, the providing unit 35 can suggest to the user U the action of checking points to be aware of when evacuating as a disaster prevention action, thereby enabling the user U to take appropriate disaster prevention action.

The providing unit 35 also provides information to the user U based on the result of the decision made by the deciding unit 32. For example, the providing unit 35 provides the user U with the information to be provided that has been decided by the deciding unit 32, or provides the user U with information to be provided that includes information indicating the evacuation site and evacuation route that have been changed by the deciding unit 32.

Figure 18 is a diagram showing another example of a display screen including provided information displayed on the terminal device 2 according to the embodiment. The display screen 77 shown in Figure 18 includes provided information including warning-related information 78 and evacuation-related information 79.

The display screen 77 shown in FIG. 18 is displayed as a pop-up on the terminal device 2 when, for example, an evacuation site for user U is not set in the user-related information, or when the congestion level determined by the determination unit 31 of the evacuation site for user U set in the user-related information is equal to or higher than a threshold value. The pop-up is displayed, for example, when the announced alert level matches the set level, or when the determination unit 32 determines an evacuation site other than the one set in the evacuation destination information included in the user setting information.

The warning-related information 78 includes information on the disaster prevention TL top that is extracted when the notification level is alert level 4 and the risk check at user U's base is NG.

The evacuation-related information 79 includes information indicating evacuation locations, evacuation routes, and evacuation timing. In the evacuation-related information 79, the evacuation locations and evacuation routes are depicted on a map in addition to being displayed as text information. This allows the user U to evacuate to an evacuation location, evacuation route, and evacuation timing appropriate to the evacuation situation, etc., thereby more appropriately supporting the user U in disaster prevention.

The evacuation-related information 79 may include information such as the current congestion level of each evacuation site, changes in the congestion level of each evacuation site, the current number of evacuees, and attributes of the people currently evacuating. This information is displayed on the terminal device 2, for example, by clicking on the mark of the evacuation site on the map in the evacuation-related information 79, but is not limited to this example. The color of the mark of the evacuation site on the map can also be changed depending on the current congestion level of the evacuation site. For example, in the evacuation-related information 79, the redder the mark of the evacuation site is the higher the current congestion level of the evacuation site.

In addition, when the evacuation destination confirmation button 71h is selected, the providing unit 35 can provide the user U with information including information indicating the evacuation location, evacuation route, and evacuation timing determined by the determining unit 32 as provided information, instead of or in addition to the evacuation destination information included in the user setting information. In this case, the provided information includes information indicating the reason why the information indicating the evacuation location, evacuation route, and evacuation timing determined by the determining unit 32 is included. The reason may be, for example, that the evacuation location set by the user U is crowded, or that it is difficult to move along the evacuation route to the evacuation location set by the user U.

In addition, the providing unit 35 can also display, on the terminal device 2, information indicating the evacuation site, evacuation route, and evacuation timing of the user U determined by the determining unit 32 based on information on the congestion level of the evacuation site and area state information during past disasters, as information on a recommended evacuation site when the "Evacuation Site" tab is selected on the evacuation destination editing screen 62. This allows the user U to set a more appropriate evacuation site as the evacuation site for the user U.

4. Processing Procedure
Next, a procedure of information processing by the processing unit 12 of the information providing device 1 according to the embodiment will be described. Fig. 19 is a flowchart showing an example of the flow of information processing by the processing unit 12 of the information providing device 1 according to the embodiment.

As shown in FIG. 19, the processing unit 12 of the information providing device 1 determines whether or not there is an initial setting request from the terminal device 2 (step S10). If the processing unit 12 determines that there is an initial setting request (step S10: Yes), it performs initial setting processing (step S11). The processing of step S11 is the processing of steps S20 to S25 shown in FIG. 20, and will be described in detail later.

When the processing of step S11 is completed or when it is determined that there is no initial setting request (step S10: No), the processing unit 12 determines whether or not it is time to provide disaster prevention information (step S12). The timing to provide disaster prevention information is, for example, a timing that occurs at a preset cycle, but is not limited to such an example.

When the processing unit 12 determines that it is time to provide disaster prevention information (step S12: Yes), it executes a disaster prevention information provision process (step S13). The process of step S13 is the process of steps S30 to S34 shown in FIG. 21, and will be described in detail later.

When the processing of step S13 is completed, or when it is determined that it is not time to provide disaster prevention information (step S12: No), the processing unit 12 determines whether it is time to provide evacuation information (step S14). In step S14, the processing unit 12 determines that it is time to provide evacuation information when, for example, there is a request for evacuation information from the user U, or the evacuation destination confirmation button 71h is selected.

When the processing unit 12 determines that it is time to provide evacuation information (step S14: Yes), it performs evacuation information provision processing (step S15). The processing in step S15 is the processing in steps S40 to S44 shown in FIG. 22, and will be described in detail later.

When the processing of step S15 is completed, or when it is determined that it is not time to provide evacuation information (step S14: No), the processing unit 12 determines whether or not there is a request from the user U to transmit disaster prevention information (step S16).

When the processing unit 12 determines that there is a request to transmit disaster prevention information (step S16: Yes), the processing unit 12 generates disaster prevention information based on the user information corresponding to the user U who made the request to transmit disaster prevention information and the disaster-related information (step S17). Then, the processing unit 12 provides the disaster prevention information generated in step S17 to the user U who made the request to transmit disaster prevention information (step S18).

When the processing of step S18 is completed, or when it is determined that there is no request to transmit disaster prevention information (step S16: No), the processing unit 12 determines whether or not it is time to end the operation (step S19). For example, when the power supply of the information providing device 1 is turned off, or when it is determined that an end operation has been performed by operating an operation unit (not shown) of the information providing device 1, the processing unit 12 determines that it is time to end the operation.

If the processing unit 12 determines that the operation end time has not yet arrived (step S19: No), it transitions to step S10, and if it determines that the operation end time has arrived (step S19: Yes), it terminates the processing shown in FIG. 19.

Fig. 20 is a flowchart showing an example of the flow of the initial setting process by the processing unit 12 of the information providing device 1 according to the embodiment. As shown in Fig. 20, the processing unit 12 performs an estimated risk check process to determine the degree of impact of the disaster on the user U based on the user information transmitted from the terminal device 2 of the user U (step S20).

Next, the processing unit 12 performs an action start timing setting process to set the action start timing, which is the timing to start evacuation action for user U, based on the degree of impact of the disaster on user U determined in step S20 or a request from user U (step S21).

Next, the processing unit 12 generates stockpile information indicating a stockpile list, which is a list of stockpile items required by the user U, based on the user information transmitted from the terminal device 2 of the user U, and performs a stockpile notification process to notify the user U of the generated stockpile information (step S22).

Next, the processing unit 12 performs a contact setting process to set a contact based on the information transmitted from the terminal device 2 of the user U (step S23). The processing unit 12 also performs an evacuation destination setting process to set an evacuation destination based on the information transmitted from the terminal device 2 of the user U (step S24).

Next, the processing unit 12 generates disaster prevention information including information on a disaster prevention timeline corresponding to the user U, performs a disaster prevention information notification process to notify the user U of the generated disaster prevention information (step S25), and ends the process shown in FIG. 20.

Figure 21 is a flowchart showing an example of the flow of disaster prevention information provision processing by the processing unit 12 of the information provision device 1 according to the embodiment. As shown in Figure 21, the processing unit 12 acquires user information, which is information about each user U, from the storage unit 11 or each terminal device 2 (step S30), and also acquires disaster-related information from the disaster-related information provision device 3 (step S31).

Next, the processing unit 12 determines whether or not it is time to notify each user U of disaster prevention information based on the user information acquired in step S30 and the disaster-related information acquired in step S31 (step S32).

When the processing unit 12 determines that it is time to notify the user of disaster prevention information (step S32: Yes), the processing unit 12 generates disaster prevention information based on the user information and disaster-related information of the user U for whom it is time to notify the user of disaster prevention information (step S33). Then, the processing unit 12 provides the disaster prevention information generated in step S33 to the user U for whom it is time to notify the user of disaster prevention information (step S34).

When the processing of step S34 is completed, or when it is determined that the timing for notifying disaster prevention information has not arrived (step S32: No), the processing unit 12 ends the processing shown in FIG. 21.

Figure 22 is a flowchart showing an example of the flow of evacuation information provision processing by the processing unit 12 of the information provision device 1 according to the embodiment. As shown in Figure 22, the processing unit 12 acquires evacuation information from the evacuation information provision device 4 (step S40), and acquires area status information from the area status information provision device 5 (step S41). The processing unit 12 also acquires user information, which is information about each user U, from the storage unit 11 or each terminal device 2 (step S42).

Next, the processing unit 12 determines information related to the evacuation of user U as information to be provided based on the evacuation information acquired in step S40, the area status information acquired in step S41, and the user information acquired in step S42 (step S43). The information related to the evacuation of user U includes information such as the evacuation location, evacuation route, and evacuation timing of user U, and this information is determined based on the evacuation information, the area status information, and the user information.

When the processing of step S43 is completed, the processing unit 12 provides the information to be provided determined in step S43 to the user U (step S44) and ends the processing of FIG. 22.

5. Modifications

The Various Procedures button 71l is a button for carrying out procedures such as application for subsidies, benefits, or tax reduction measures, and the user U can select the Various Procedures button 71l by operating the terminal device 2. When the Various Procedures button 71l is selected, the providing unit 35 provides the user U with information such as a procedure list for carrying out various applications. The procedure list information includes links to the procedure destination, and the user U can carry out the desired procedure by selecting such a link.

The disaster prevention timeline information 70 shown in FIG. 23(b) may also include, for example, an evacuation history confirmation button for displaying information on the evacuation history of other users U at the time of the disaster that is the subject of recovery or reconstruction, a damage status confirmation button for confirming the damage status caused by the disaster that is the subject of recovery or reconstruction, and a restoration and reconstruction status confirmation button for confirming the status of restoration and reconstruction from the disaster that is the subject of recovery or reconstruction.

The providing unit 35 can also, for example, tally up the evacuation destination settings made by other users U whose base locations are included in the area including the base location of the user U, and display the tally results by adding an evacuation destination addition screen 60 or an evacuation destination editing screen 62. The tally results include, for each evacuation destination, the total number of users U who have set it as an evacuation destination, the number of users U for each attribute, etc.

In addition, for users U who set an evacuation location a long time ago (e.g., more than one year ago), the providing unit 35 can also prompt the users U to update their evacuation location by displaying a pop-up message on the terminal device 2 prompting them to check the evacuation location or the disaster prevention timeline information 70.

The providing unit 35 can also display a pop-up message on the terminal device 2 to encourage a user U who has not displayed the disaster prevention timeline information 70 on the terminal device 2 for a certain period of time (e.g., one month) or more to check the disaster prevention timeline information 70.

6. Hardware Configuration
The information providing device 1 or the terminal device 2 according to the above-described embodiment is realized by a computer 80 having a configuration as shown in Fig. 24, for example. The information providing device 1 will be described below as an example. Fig. 24 is a hardware configuration diagram showing an example of a computer 80 that realizes the functions of the information providing device 1 according to the embodiment. The computer 80 has a CPU 81, a RAM 82, a ROM (Read Only Memory) 83, a HDD (Hard Disk Drive) 84, a communication interface (I/F) 85, an input/output interface (I/F) 86, and a media interface (I/F) 87.

The CPU 81 operates based on the programs stored in the ROM 83 or the HDD 84, and controls each part. The ROM 83 stores a boot program executed by the CPU 81 when the computer 80 starts up, and programs that depend on the hardware of the computer 80.

The HDD 84 stores programs executed by the CPU 81 and data used by such programs. The communication interface 85 receives data from other devices via the communication network 6 (see FIG. 2) and sends the data to the CPU 81, and transmits data generated by the CPU 81 to other devices via the communication network 6.

The CPU 81 controls output devices such as a display and a printer, and input devices such as a keyboard and a mouse, via the input/output interface 86. The CPU 81 acquires data from the input devices via the input/output interface 86. The CPU 81 also outputs data generated via the input/output interface 86 to the output devices.

The media interface 87 reads a program or data stored in the recording medium 88 and provides it to the CPU 81 via the RAM 82. The CPU 81 loads the program from the recording medium 88 onto the RAM 82 via the media interface 87 and executes the loaded program. The recording medium 88 is, for example, an optical recording medium such as a DVD (Digital Versatile Disc) or a PD (Phase change rewritable Disc), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory.

For example, when the computer 80 functions as the information providing device 1 according to the embodiment, the CPU 81 of the computer 80 executes a program loaded onto the RAM 82 to realize the functions of the processing unit 12. In addition, the data in the storage unit 11 is stored in the HDD 84. The CPU 81 of the computer 80 reads and executes these programs from the recording medium 88, but as another example, these programs may be obtained from another device via the communication network 6.

8. Effects
As described above, the information providing device 1 according to the embodiment includes an acquisition unit 30, a determination unit 32, and a provision unit 35. The acquisition unit 30 acquires evacuation information including information on evacuation against a disaster and information indicating the evacuation status of each of the multiple users U, and user information including information on the users U. The determination unit 32 determines information to be provided, which is information on evacuation according to the users U for the users U before evacuation, based on the evacuation information and user information acquired by the acquisition unit 30. The provision unit 35 provides the information to be provided determined by the determination unit 32 to the users U before evacuation. This allows the information providing device 1 to provide information on evacuation according to the users U for the users U before evacuation, and more appropriately support disaster prevention for the users U.

The determination unit 32 also determines, as the information to be provided, information that includes information regarding evacuation according to the attributes of the user U as information regarding evacuation according to the user U. This allows the information providing device 1 to provide information regarding evacuation according to the attributes of the user U, and to more appropriately support the user U in disaster prevention.

The determination unit 32 also determines information including information indicating the evacuation location, evacuation route, and evacuation timing of the user U before evacuation as information to be provided to the user U before evacuation. This allows the information providing device 1 to more appropriately provide information regarding evacuation that suits the user U, and the user U before evacuation can evacuate to an evacuation location, evacuation route, and evacuation timing that suits the evacuation situation of other users U, thereby more appropriately supporting the user U in disaster prevention.

The determination unit 32 also determines that information further including information indicating the evacuation means of the user U before evacuation is to be provided to the user U before evacuation. This allows the information providing device 1 to more appropriately provide information regarding evacuation that is appropriate for the user U, and the user U before evacuation can evacuate using an appropriate evacuation means that is appropriate for the evacuation situation, etc.

The information providing device 1 also includes a determination unit 31 that determines the current or future congestion level of the evacuation site. The determination unit 32 changes the evacuation site of at least one of the user U before evacuation and the user U in the middle of evacuation based on the result of the congestion level determination by the determination unit 31. The providing unit 35 provides information on the evacuation site changed by the determination unit 32 to at least one of the user U before evacuation and the user U in the middle of evacuation. As a result, the information providing device 1 changes the evacuation site of at least one of the user U before evacuation and the user U in the middle of evacuation in accordance with the current or future congestion level of the evacuation site, thereby more appropriately supporting disaster prevention for the user U.

The acquisition unit 30 also acquires area status information indicating the status of an area including each of the travel routes between the bases of the multiple users U and the evacuation site. The determination unit 32 determines or changes an evacuation route for at least one of the users U before evacuation and the users U during evacuation, based on the area status information acquired by the acquisition unit 30. As a result, the information providing device 1 determines an evacuation route according to the status of an area including each of the travel routes between the bases of the multiple users U and the evacuation site, and can therefore present the users U with evacuation routes that avoid travel routes that are difficult to pass through, for example, and can more appropriately support the users U in disaster prevention.

The acquisition unit 30 also acquires location information indicating the location of each of the multiple users U. The determination unit 32 extracts users U who are away from the evacuation area from among the multiple users U based on the location information acquired by the acquisition unit 30, and determines an action to be proposed to the extracted users U. The provision unit 35 provides proposed information including information on the action determined by the determination unit 32. This allows the information provision device 1 to suggest actions to users U who are away from the evacuation area, and more appropriately support disaster prevention for users U.

The acquisition unit 30 also acquires traffic information indicating the state of transportation from the location of the user U, who is away from the evacuation area, to the user U's base of operations or the evacuation site of the user U. The decision unit 32 decides an action to be proposed to the user U, who is away from the evacuation area, based on the traffic information and location information acquired by the acquisition unit 30. This allows the information providing device 1 to suggest an action to the user U, who is away from the evacuation area, depending on the state of transportation, thereby more appropriately supporting the user U in disaster prevention.
