During a disaster or emergency, each evacuee needs to decide which evacuation site to evacuate to. However, people who require special consideration when evacuating, such as elderly people or families with infants, not only take time to start evacuation, but also take time to move, so they arrive at the evacuation site late. By the time such people arrive at the evacuation site, the site may be full, and they may have to move to another evacuation site. Even when hotels and other facilities are used as alternative evacuation sites, reservations are generally accepted on a first-come, first-served basis, and reservations cannot be made once the site is full. On the other hand, there are also evacuees who are not special consideration and can evacuate long distances immediately, such as those who can evacuate by private car. Therefore, it is desirable to provide appropriate evacuation sites according to the situation of the evacuees.

The embodiment of the present invention was made taking these circumstances into consideration, and aims to provide evacuation support technology that can reserve an appropriate evacuation site depending on the situation of the evacuees.

The evacuation support system according to an embodiment of the present invention includes an evacuation site database that stores evacuation site information related to evacuation sites; a current location acquisition unit that acquires a current location of an evacuee in an emergency; an attribute information acquisition unit that acquires attribute information of the evacuee; a priority determination unit that determines a priority of the evacuee based on the current location and the attribute information; an evacuation action determination unit that determines an evacuation action predicted to be taken by the evacuee based on the current location and the attribute information; a candidate display unit that displays candidates for the evacuation site to which the evacuee can take evacuation on an evacuee terminal handled by the evacuee based on the evacuation action and the evacuation site information; The system comprises an evacuation site reservation unit that accepts reservations from a terminal for evacuees, a reservation decision unit that decides whether to accept or reject the reservation based on the priority of the evacuee whose reservation has been accepted, and an evacuation data accumulation database that stores evacuee identification information that can individually identify the evacuee in association with the evacuation site for which the reservation has been accepted , wherein the priority decision unit ranks the evacuees according to their priority, and the reservation decision unit decides whether to accept or reject the reservation for the evacuation site in order, starting with the evacuee with the highest priority rank, and notifies at least the evacuee with the lowest priority rank that they are waiting for a reservation decision until the reservation is decided .

Embodiments of the present invention provide evacuation support technology that can reserve an appropriate evacuation site depending on the situation of the evacuees.

Below, we will explain in detail the embodiments of the evacuation support system and evacuation support method with reference to the drawings.

In the event of a disaster such as torrential rain or a typhoon that may cause flooding or landslides, or in the event of an emergency such as a nuclear power plant accident, local residents decide whether or not to evacuate based on the "alert level" issued by the city/town/village disaster prevention center or the Japan Meteorological Agency. Furthermore, they must decide for themselves when to evacuate and act accordingly. Generally, "alert level 2" is announced by the Japan Meteorological Agency as a heavy rain warning or flood warning, while "alert level 3 or higher" is issued by the city/town/village disaster prevention center as information to begin evacuation, evacuation recommendations, or evacuation orders. When an alert is issued, local residents must check the hazard map for areas at risk of disaster, evacuation sites, evacuation routes, and evacuation timing, and consider appropriate evacuation actions.

In the event of a nuclear disaster, local disaster prevention plans are being formulated based on the principles of the relevant local government's nuclear disaster countermeasures guidelines. However, the optimization of protection in local disaster prevention plans uses the time it takes for the public to complete evacuation as a judgment indicator, and does not take into account whether the remaining radiation dose to the public can be reduced. In the event of a nuclear disaster, radioactive contamination distribution maps are regularly created based on forecast data on ever-changing wind direction or speed available from the Japan Meteorological Agency and other sources. Therefore, it is desirable to provide rapid support for selecting the best evacuation route and evacuation timing at the time of creation.

For example, even if a disaster prevention center gathers various information and determines appropriate evacuation sites and evacuation routes, confusion may arise if the instructions are not conveyed accurately to evacuees and they do not act in accordance with the instructions. Even if evacuation to an appropriate evacuation site begins following the issuance of an evacuation order, it may take time to complete the evacuation due to bad weather such as rain or snow. Furthermore, if evacuees begin evacuating before the appropriate timing, road congestion may occur, delaying the completion of the evacuation. In particular, the evacuation behavior of evacuees is influenced by the unit of action, for example, whether or not they act together with family, individuals, friends, etc. The means of transportation and the congestion of roads along the evacuation route also have a significant impact.

Therefore, it is desirable to take into consideration the circumstances of evacuees' behavior, ever-changing weather data available from the Japan Meteorological Agency and other sources, road conditions, and the dispersion of evacuation routes and evacuation timing, so as to begin evacuation via the optimal route and at the optimal timing, and also to minimize the time it takes to complete the evacuation.

In addition, evacuees may include people who require special consideration, such as elderly people or families with infants, who take a long time to evacuate, and it is desirable to provide an appropriate evacuation site according to the situation of such evacuees. In this embodiment, attribute information of the evacuees is acquired, and the priority of each evacuee is ranked based on this attribute information. Then, evacuation sites can be reserved in descending order of priority. For example, the priority of people who require special consideration is set to be high. In this way, appropriate evacuation sites can be reserved according to the situation of the evacuees. Note that people who require special consideration include pregnant women, infants, young children, elderly people, people with disabilities, sick people, etc. In other words, the attribute information includes information on the physical condition and personal status of the evacuees (age, pregnant women, people with children, people with elderly people, injuries, illnesses, etc.). Furthermore, teachers who lead a large number of students are set to have a high priority. Note that the attribute information includes information on the presence or absence of people who require special consideration, as well as the total number of people evacuating together, and the means of transportation indicating whether to move on foot or by vehicle.

Reference numeral 1 in FIG. 1 denotes the evacuation support system of this embodiment. This evacuation support system 1 is used to support evacuees R evacuating to evacuation site E in the event of an emergency such as a disaster or emergency. The evacuation support system 1 is mainly used by evacuees R or an administrator M who manages the evacuation site E. When multiple people evacuate together, a representative person among them will access the evacuation support system 1 as evacuee R. In the following explanation, when the number of evacuees R is indicated, the number refers to the number including the evacuee R (representative) who accessed the evacuation support system 1 and the evacuees R (accompanying persons) who act together with this evacuee R.

In this embodiment, multiple evacuation sites E are provided, and evacuees R can reserve the evacuation site E to which they will evacuate before starting their evacuation. The evacuation support system 1 reserves an appropriate evacuation site E according to the situation of the evacuees R, and provides information regarding appropriate evacuation routes and evacuation timing.

The evacuation support system 1 is connected to the Internet 2. This evacuation support system 1 receives various data from the Japan Meteorological Agency 3 and a traffic control center 4 via the Internet 2. Note that the system may also receive various data from other administrative agencies (e.g., local governments).

The evacuation support system 1 acquires meteorological information related to weather from, for example, the Japan Meteorological Agency 3, which is a weather information source that transmits meteorological information related to weather. The Japan Meteorological Agency 3 acquires meteorological information including the amount of rainfall, amount of snowfall, wind direction, wind speed, temperature, etc., based on, for example, data from AmeDAS. This meteorological information is then announced by the Japan Meteorological Agency 3. In addition, the meteorological information is updated every 10 minutes, and the weather information is announced each time it is updated.

The weather information also includes information on disasters such as earthquakes. Furthermore, the weather information also includes information on landslides, river flooding, tsunamis, and the like. Radioactivity information on radioactive materials released from nuclear facilities is also obtained from the Japan Meteorological Agency 3. Note that this information may also be released by other government agencies or private organizations. Furthermore, the evacuation support system 1 also obtains geographic information on geography from the Japan Meteorological Agency 3 or other government agencies (e.g., the Geospatial Information Authority of Japan) or private organizations.

The evacuation support system 1 also acquires traffic information from the traffic control center 4. The traffic information includes information about evacuation routes.

Connected to the Internet 2 are smartphones 5 and 6, a home appliance 7, a car navigation system (car navigation system) 8, a drive recorder 9, and an evacuation site camera device 10.

In this embodiment, examples of the evacuee terminals used by evacuee R include a smartphone 6, a home appliance 7, and a car navigation system 8. Also, an example of the administrator terminal used by the administrator M of the evacuation site E is a smartphone 5. Using such evacuee terminals or administrator terminals, information regarding evacuation is provided to evacuee R or administrator M.

The smartphones 5 and 6 are mobile terminals carried by the evacuee R or the manager M. The home appliance 7 is a device used by the evacuee R at home. For example, it is a device equipped with at least a display and operation buttons, such as a television, door phone, or landline phone that is installed in a typical home. The car navigation system 8 is a device installed in a vehicle that the evacuee R uses as a means of transportation when evacuating. These home appliances 7 and car navigation systems 8 are manufactured and sold in a form capable of executing an application that can be linked with the evacuation support system 1, and are already available on the market. In this way, information about the evacuation site E can be provided using a mobile terminal, home appliance, or vehicle-mounted terminal that the evacuee R uses on a daily basis.

In the following explanation, smartphones 5 and 6 will be described as representative examples of evacuee terminals or administrator terminals. Note that home appliances 7 and car navigation systems 8 can also be used in the same way as smartphones 5 and 6.

The evacuee terminal or administrator terminal may be configured as a tablet PC, notebook PC, or desktop PC. Furthermore, it may be configured as a wearable computer (smart glasses) equipped with a see-through head-mounted display. In addition, it may be configured as a device with a photographing function, a calling function, and a communication function, and may be configured as multiple devices with each function.

In this embodiment, a smartphone 6 is exemplified as a portable device that can be carried by a person. The portable device may be used by the evacuee R or a third party other than the evacuee R. For example, information on roads that are determined to be passable by the evacuee R or the like is collected using the portable device. In addition, information on roads that have become impassable due to a disaster can be collected from the evacuee R or the like.

Furthermore, as examples of on-board equipment to be installed in a vehicle, a car navigation system 8 and a drive recorder 9 installed in a specified vehicle are given as examples. The on-board equipment may be installed in a vehicle used by the evacuee R, or may be installed in a vehicle used by a third party other than the evacuee R. The car navigation system 8 and the drive recorder 9 are manufactured and sold in a form capable of transmitting various data related to road conditions to the traffic control center 4, and are assumed to be already available in the market. In this way, the latest traffic information can be obtained using on-board equipment or mobile devices already available in the market. Note that the on-board equipment may be any device capable of detecting road conditions, and may be, for example, equipment equipped with a sensor that detects road conditions using a laser or radio waves.

The evacuation site camera device 10 is installed at the evacuation site E. The evacuation site camera device 10 includes a camera installed at the evacuation site E and a transmission device for transmitting images captured by the camera to the evacuation support system 1 via the Internet 2. The evacuation support system 1 can obtain images showing the state of each evacuation site E using the evacuation site camera device 10.

Next, the system configuration of the evacuation support system 1 will be explained with reference to the block diagrams shown in Figures 2 and 3.

As shown in FIG. 2, the evacuation support system 1 includes a main control unit 11 and a communication unit 12. The main control unit 11 provides overall control of the evacuation support system 1. The communication unit 12 communicates with other computers via a communication line such as the Internet 2. The evacuation support system 1 of this embodiment is connected to the Internet 2 via the communication unit 12, and transmits and receives various information to and from smartphones 5 and 6 used by evacuees R or managers M. In addition, it transmits and receives various information to and from computers installed in the Japan Meteorological Agency 3 or the traffic control center 4.

In this embodiment, the evacuation support system 1 and the other computers are connected to each other via the Internet 2, but other configurations are also possible. For example, they may be connected to each other via a LAN (Local Area Network), a WAN (Wide Area Network), or a mobile communication network.

The main control unit 11 controls the images displayed on the display 44 (FIG. 6) of the smartphone 5, 6 used by the evacuee R or the manager M. The display 44 may be separate from the terminal body or may be integrated with it.

In this embodiment, the display 44 is used as an example of a device that displays images, but other configurations are also possible. For example, information may be displayed using a head-mounted display or a projector. Furthermore, a printer that prints information on paper media may be used instead of a display.

The evacuation support system 1 further includes a meteorological environment database 13, an evacuation site database 14, and an evacuation data accumulation database 15. These are collections of information stored in memory or a HDD and organized so that they can be searched or accumulated.

The meteorological environment database 13 stores meteorological information, radiation information, and environmental condition information sent from the Japan Meteorological Agency 3.

The evacuation site database 14 stores evacuation site information about evacuation sites. It mainly stores information about the location (address) of evacuation site E, the number of people it can accommodate, the number of stockpiled items, the facilities, etc. The evacuation site information also includes information indicating whether evacuation site E is available for use, i.e., whether it has been destroyed by a disaster.

The evacuation data accumulation database 15 stores evacuee identification information (evacuee ID) that can individually identify evacuees R in association with evacuation sites E for which reservations have been accepted. It also stores information regarding evacuation routes, etc. In this embodiment, the evacuation data accumulation database 15 stores an evacuation site management table (Figure 4) and an evacuee management table (Figure 5).

The evacuation support system 1 of this embodiment is configured as a computer having hardware resources such as a CPU, ROM, RAM, and HDD, and in which software-based information processing is realized using the hardware resources as the CPU executes various programs. Furthermore, the evacuation support method of this embodiment is realized by having the computer execute the various programs.

Each component of the evacuation support system 1 does not necessarily have to be provided on a single computer. For example, a single system may be realized using multiple computers connected to each other via a network. For example, the weather environment database 13, the evacuation site database 14, and the evacuation data accumulation database 15 may be provided on other computers connected via the Internet 2.

As shown in FIG. 3, the main control unit 11 includes a traffic information acquisition unit 16, a weather information acquisition unit 17, a radiation information acquisition unit 18, an emergency information distribution unit 19, an attribute information input display unit 20, an attribute information input acceptance unit 21, a current position acquisition unit 22, an attribute information acquisition unit 23, a priority determination unit 24, an evacuation behavior determination unit 25, a candidate display unit 26, an evacuation site reservation unit 27, a reservation decision unit 28, a reservation information distribution unit 29, a reservation information display unit 30, an evacuation route candidate creation unit 31, an evacuation route display unit 32, an evacuation route acceptance unit 33, an evacuation timing decision unit 34, an evacuation timing display unit 35, an evacuation route update unit 36, an image distribution unit 37, a congestion degree calculation unit 38, a congestion degree distribution unit 39, an evacuation timing judgment unit 40, a warning display unit 41, a timing information distribution unit 42, and a timing information presentation unit 43. These are realized by the CPU executing a program stored in the memory or HDD.

The traffic information acquisition unit 16 acquires traffic information on roads based on data sent from the traffic control center 4. In this embodiment, the traffic information is used as a condition for selecting an evacuation site E and an evacuation route. Then, candidate evacuation sites E and evacuation routes to which the evacuee R can take refuge are displayed on the smartphone 6 of the evacuee R. In this way, candidate evacuation sites E and evacuation routes can be presented to the evacuee R, taking into account traffic conditions that change during an emergency.

The weather information acquisition unit 17 acquires weather information on the basis of data sent from a weather information source that transmits weather information on the weather, for example, the Japan Meteorological Agency 3. In this embodiment, the weather information is used as a condition for selecting an evacuation site E and an evacuation route. Then, candidate evacuation sites E and evacuation routes to which the evacuee R can take refuge are displayed on the smartphone 6 of the evacuee R. In this way, candidate evacuation sites E and evacuation routes can be presented to the evacuee R, taking the weather into consideration.

The radioactivity information acquisition unit 18 acquires radioactivity information on radioactive materials released from nuclear facilities based on data sent from the Japan Meteorological Agency 3. In this embodiment, the radioactivity information is used as a condition for selecting an evacuation site E and an evacuation route. Then, candidate evacuation sites E and evacuation routes to which the evacuee R can take refuge are displayed on the smartphone 6 of the evacuee R. In this way, candidate evacuation sites E and evacuation routes can be presented to the evacuee R, taking into account the status of radioactive materials released from the nuclear facility.

For example, in the event of a nuclear disaster, it is possible to analyze not only meteorological information but also radioactivity information, and use wind speed, direction, and volume to determine the state of radioactive material dispersion and to predict its dispersion. By incorporating this information as environmental data, it is possible to provide evacuee R with safer evacuation routes and evacuation timings that minimize exposure to radioactive materials.

When an emergency occurs, the emergency information distribution unit 19 distributes emergency information indicating the occurrence of an emergency to the smartphone 6 (evacuee terminal) of the evacuee R. The emergency information is distributed, for example, in the form of an emergency email (Figure 6).

The attribute information input display unit 20 displays an input form on the smartphone 6 of the evacuee R, which requests the input of attribute information. For example, an input form (attribute information input screen) is displayed on the display 44 of the smartphone 6 of the evacuee R in association with the distribution of emergency information (Figure 7). In this way, the attribute information of the evacuee R can be obtained immediately when an emergency occurs. Specifically, the attribute information input display unit 20 transmits data for displaying the input form to the smartphone 6. The smartphone 6 then displays the input form on the display 44 based on the received data.

The attribute information input reception unit 21 receives the input of attribute information based on an input form (FIG. 7) displayed on the display 44 of the smartphone 6 of the evacuee R. In this way, attribute information can be obtained through input by the evacuee R. The display 44 of the smartphone 6 functions as a touch panel. Input operations are performed by touching the display 44. Furthermore, the attribute information may be input in advance not only in an emergency but also during normal times.

The current position acquisition unit 22 acquires the current position (current location) of the evacuee R in the event of an emergency. The smartphone 6 carried by the evacuee R can acquire its own position using a satellite positioning system. The current position of this smartphone 6 is transmitted to the evacuation support system 1 via the Internet 2. Alternatively, the evacuee R may manually input his/her current position using an input form, and this information may be transmitted to the evacuation support system 1 via the Internet 2. The current position acquisition unit 22 acquires the current position of the evacuee R based on the data sent from the smartphone 6.

The attribute information acquisition unit 23 acquires attribute information of the evacuee R. Specifically, the attribute information entered into the input form (Figure 7) displayed on the display 44 of the smartphone 6 is sent to the evacuation support system 1. The attribute information acquisition unit 23 acquires the attribute information received from the smartphone 6.

The priority determination unit 24 determines the priority of the evacuees R based on the current location and attribute information acquired from the smartphone 6 of the evacuees R. In this embodiment, each evacuee R is ranked according to its priority. For example, evacuees R including people with special consideration are ranked with the highest priority "A", and evacuees R with the lowest priority are ranked with "D". Reservations for evacuation sites E are then made in order starting from evacuees R with the highest priority.

In this embodiment, the ranking is based on the ease of evacuation. For example, if the means of transportation is walking, it is not possible to travel long distances and evacuation is difficult, so it is assigned the highest priority rank of "A". On the other hand, if a vehicle can be used as a means of transportation, it is possible to travel long distances and evacuation is easy, so it is assigned the lowest priority rank of "D". Also, for example, if evacuee R is a group (if there are multiple people evacuating together), it is difficult to evacuate, so it is assigned the highest priority rank of "A". On the other hand, if evacuee R is an individual (if there is only one person evacuating), it is easy to evacuate, so it is assigned the lowest priority rank of "D". In this way, ranking is performed based on the physical condition and personal circumstances of evacuee R.

The evacuation behavior judgment unit 25 judges the evacuation behavior predicted to be taken by evacuee R based on the current location and attribute information. For example, based on the current location and attribute information of evacuee R, it constructs an evacuation behavior judgment model that can judge the movement range, movement speed, number of people evacuating together, presence or absence of people requiring special consideration, etc. of evacuee R. The evacuation behavior judgment unit 25 predicts the future behavior of evacuee R using this evacuation behavior judgment model and makes a judgment on it.

The candidate display unit 26 displays candidates for evacuation sites E to which the evacuee R can evacuate, based on the evacuation behavior and evacuation site information, on the smartphone 6 used by the evacuee R. For example, a list of evacuation sites E to which the evacuee R can evacuate (Figure 8) is displayed on the display 44 of the smartphone 6.

The evacuation site reservation unit 27 accepts a reservation for an evacuation site E displayed as a candidate from the smartphone 6 used by the evacuee R. For example, when the evacuee R applies for a reservation for the evacuation site E that he or she wishes to use from the list of candidate evacuation sites E (Figure 8), the evacuation site reservation unit 27 accepts the reservation by receiving information including the application details from the smartphone 6. Note that this acceptance also includes the acceptance of an application that does not use the evacuation site E.

The reservation decision unit 28 decides whether to accept or reject a reservation based on the priority of the evacuee R whose reservation has been accepted. For example, in the case of evacuation site E where there are many people wishing to make reservations, a decision is made to accept the reservation of evacuee R of rank "A" and to reject the reservation of evacuee R of rank "D". Furthermore, reservations for evacuee R of rank "A" are decided immediately, and reservations for evacuee R of rank "D" are decided after a predetermined time has passed. Note that if it takes time for a reservation to be decided, a notification is sent to evacuee R that the reservation is waiting to be decided.

The reservation information distribution unit 29 distributes reservation information that can identify whether or not an evacuee R who has arrived at an evacuation site E is a person whose reservation has been accepted, based on information accumulated in the evacuation data accumulation database 15. This reservation information is distributed to the smartphones 5 and 6 of the evacuee R or the manager M.

The reservation information display unit 30 displays the reservation information on the display 44 of the smartphone 5 of the evacuee R or the manager M. In this way, the manager M of the evacuation site can identify whether or not the reservation of the evacuee R has been accepted. For example, a screen indicating that the reservation for the evacuee R for the evacuation site E has been accepted may be displayed on the display 44 of the smartphone 6 of the evacuee R, and the screen may be shown to the manager M. Also, a specified two-dimensional barcode may be displayed on the display 44 of the smartphone 6 of the evacuee R, and the two-dimensional barcode may be read by the smartphone 5 of the manager M, allowing the smartphone 5 of the manager M to check whether or not the reservation has been accepted.

For example, if evacuee R arrives at an evacuation site where the reservation has not been accepted, he or she may be turned away at the entrance to evacuation site E. Therefore, evacuee R will go to the appropriate evacuation site E.

The evacuation route candidate creation unit 31 creates candidates for evacuation routes that can be used by the evacuee R based on the information accumulated in the evacuation data accumulation database 15. For example, when the evacuation site E for the evacuee R is determined, a candidate evacuation route from the current location of the evacuee R to the evacuation site E is created based on the evacuation site information, current location, attribute information, traffic information, weather information, radiation information, geographic information, etc.

The evacuation route display unit 32 displays candidate evacuation routes on the smartphone 6 of the evacuee R. For example, a list of candidate evacuation routes (not shown) that the evacuee R can take is displayed on the display 44 of the smartphone 6.

The evacuation route reception unit 33 receives from the smartphone 6 of the evacuee R whether or not to use the evacuation route displayed as a candidate. For example, when the evacuee R selects an evacuation route to be used from a list of candidate evacuation routes (not shown), the evacuation route reception unit 33 receives information including the selection from the smartphone 6, thereby accepting the selection of the evacuation route. Note that these options also include the option of not using an evacuation route.

The evacuation timing determination unit 34 determines the evacuation timing of the evacuation route to be used by the evacuee R. For example, the evacuation timing is determined based on evacuation site information, current location, attribute information, traffic information, weather information, radiation information, geographic information, and the like. The evacuation timing includes the "evacuation start time" and the "evacuation completion time." If a rest stop is made during the evacuation, the evacuation timing may also include the arrival time at the rest site and the departure time from the rest site.

The evacuation timing display unit 35 displays information indicating the evacuation timing on the smartphone 6 of the evacuee R. In this way, the evacuee R can understand the appropriate timing for evacuation. For example, the "evacuation start time" and "evacuation completion time" are displayed on the display 44 of the smartphone 6 of the evacuee R (Figure 9). In this embodiment, the "evacuation start time" is the time at which the evacuee R starts moving from the current location at the time the reservation is applied for. Also, the "evacuation completion time" is the time at which the evacuee R arrives at the evacuation site E.

In this embodiment, once an evacuation route is determined, the timing of evacuation is determined based on predicted information on the spread of the disaster, which is included in weather information and the like. Furthermore, by predicting road congestion when many evacuees R move at the same time, the optimal timing of evacuation is determined so that evacuees R who will take the longest time to evacuate start evacuation in order. In this way, congestion at evacuation sites E and evacuation routes can be avoided, and the time it takes to complete evacuation can be shortened. Furthermore, by presenting a safe evacuation route, the rescue rate can be improved.

The evacuation route update unit 36 updates the evacuation route used by the evacuee R based on constantly updated traffic information, weather information, radiation information, and the like. This updating of the evacuation route is performed, for example, every 10 minutes. When the evacuation route is updated, the candidate evacuation routes may be notified to the evacuee R again, and the evacuee R may select a new evacuation route from among these. For example, if after the evacuation has begun, a road that was set as an evacuation route is determined to be impassable due to damage caused by the disaster, another candidate evacuation route is displayed and can be selected again. Taking these factors into consideration, the evacuee R is able to select the optimal evacuation route.

The image distribution unit 37 distributes an image of the evacuation site E taken by the evacuation site camera device 10 to the smartphone 6 of the evacuee R. In this way, the evacuee R can understand the degree of congestion at the candidate evacuation site E from the image. For example, an image of the evacuation site E is taken by the evacuation site camera device 10. Then, when the evacuee R makes a reservation for the evacuation site E, an image showing the situation of the candidate evacuation site E is displayed on the display 44 of the smartphone 6 of the evacuee R, allowing the evacuee R to understand the degree of congestion at the evacuation site E. The evacuee R can select an evacuation site E depending on the degree of congestion.

The congestion degree calculation unit 38 calculates the congestion degree of the evacuation site E based on an image of the evacuation site E captured by the evacuation site camera device 10. For example, the number of people present in the evacuation site E is counted based on an image captured by the evacuation site camera device 10. The number of people present is then compared with the capacity of the evacuation site E to calculate the congestion degree of the evacuation site E. The congestion degree is updated every fixed time (for example, every 30 minutes or every hour).

The congestion level distribution unit 39 distributes the congestion level of the evacuation site E displayed as a candidate to the smartphone 6 of the evacuee R. For example, when the evacuee R makes a reservation for the evacuation site E, the congestion level of the candidate evacuation site E is distributed. In this way, the congestion level of the evacuee R who is scheduled to evacuate can be provided to the evacuee R who is scheduled to evacuate, without distributing an image of the evacuee R who is in the evacuation site E. This makes it possible to protect the privacy of the evacuee who is in the evacuation site E. Note that the congestion level, such as "**%", may be displayed together with the image of the evacuation site E.

By providing evacuee R with an image of evacuation site E or information such as the degree of congestion, evacuee R can check the living conditions at the evacuation destination for himself/herself and select evacuation site E. This makes it possible to guide him/her to the most suitable evacuation site E. In addition, by being able to display the status of evacuation site E, it is possible to improve the rescue rate, such as hospital emergency response measures.

The evacuation timing determination unit 40 determines whether or not evacuee R is evacuating at the determined evacuation timing based on the updated current location of evacuee R. For example, the current location is periodically acquired from evacuee R's smartphone 6. Then, it determines whether or not the current location has changed, that is, whether evacuee R is moving. Based on this determination, it determines whether or not evacuee R is evacuating at the appropriate evacuation timing.

The warning display unit 41 displays information indicating a warning on the smartphone 6 of the evacuee R when it is determined that the evacuee R has not evacuated at the determined evacuation timing. In this way, it is possible to warn the evacuee R if the evacuee R's evacuation timing is too early or too late. The information indicating the warning is notified using e-mail or the like. It is also possible to notify the evacuee R's smartphone 6 by calling the evacuee R with an automated voice message. In this way, it is possible to spread out the evacuation timing of each evacuee R. As a result, confusion or congestion during the evacuation can be avoided, and as a result, the evacuation time can be shortened and the evacuation can be completed safely.

The timing information distribution unit 42 distributes timing information that can identify whether or not an evacuee R who has arrived at an evacuation site E has evacuated at the determined evacuation timing. This timing information is distributed to the smartphones 5 and 6 of the evacuee R or the manager M.

The timing information presentation unit 43 displays the timing information on the display 44 of the smartphone 5 of the evacuee R or the manager M. In this way, the manager M of the evacuation site E can identify whether the evacuee R has evacuated at the appropriate evacuation timing. For example, a screen showing the name of the evacuation site E and the evacuation completion time may be displayed on the display 44 of the smartphone 6 of the evacuee R, and the screen may be shown to the manager M. Also, a specified two-dimensional barcode may be displayed on the display 44 of the smartphone 6 of the evacuee R, and the name of the evacuation site E and the evacuation completion time may be confirmed on the smartphone 5 of the manager M by reading the two-dimensional barcode.

As shown in FIG. 4, the evacuation site management table stores the number of people that can be accommodated, the number of people reserved, the current number of people that can be accommodated, and the number of vacancies, in association with the evacuation site ID. Note that information other than the above may also be registered in the evacuation site management table.

In the evacuation site ID field, an evacuation site ID is registered, which is evacuation site identification information that can individually identify each evacuation site E. This evacuation site ID is the primary key of the evacuation site management table. An evacuation site ID is assigned to each evacuation site E. Note that an evacuation site ID may be assigned in advance under normal circumstances, and a temporary evacuation site ID may be assigned to an evacuation site E that is temporarily set up in an emergency. The information registered in the evacuation site management table is distributed to the smartphone 5 of the manager M of the evacuation site E corresponding to the evacuation site ID. The manager M can grasp the status of the evacuation site E that he or she manages based on the evacuation site management table.

The total number of evacuees R that can be accommodated in the evacuation site E corresponding to the evacuation site ID is registered in the accommodating capacity field. The evacuation site ID and the accommodating capacity may be stored in the evacuation site database 14 as evacuation site information.

The number of people with reservations field registers the total number of evacuees R who have reserved the evacuation site E corresponding to the evacuation site ID. This number of people with reservations is updated, for example, when an evacuee R makes a reservation on smartphone 6.

The current capacity field registers the total number of evacuees R currently using the evacuation site E corresponding to the evacuation site ID.

The number of vacant spaces is the number of people currently available at the evacuation site E corresponding to the evacuation site ID. Note that this number of vacant spaces does not include the number of people who have already been booked. In other words, people who have evacuated to evacuation site E without making a reservation can use evacuation site E only if there are vacant spaces. The current capacity and number of vacant spaces are updated, for example, when administrator M accepts a request for evacuation site E on smartphone 5.

As shown in FIG. 5, the evacuee management table stores the total number of people, whether or not there are people requiring special consideration, the means of transportation, the priority rank, the evacuation site ID, the evacuation start time, and the evacuation completion time in association with the evacuee ID. Note that information other than the above may also be registered in the evacuee management table.

In the evacuee ID field, an evacuee ID is registered, which is evacuee identification information that can individually identify each evacuee R. This evacuee ID is the primary key of the evacuee management table. An evacuee ID is assigned to an evacuee R who accesses the evacuation support system 1 using a smartphone 6. Note that an evacuee ID may be assigned to an evacuee R in advance under normal circumstances.

The total number of people field registers the total number of evacuees R corresponding to the evacuee ID (total number of people). This total number includes evacuees R (representative) who accessed the evacuation support system 1 with the smartphone 6, and evacuees R (accompanying people) who act together with this evacuee R. This total number is attribute information of evacuees R.

In the "Whether there are people who need special consideration" field, information is registered that indicates whether or not the evacuee R corresponding to the evacuee ID includes a person who needs special consideration. For example, if evacuee R includes a person who needs special consideration, "Yes" is registered in the "Whether there are people who need special consideration" field. If evacuee R does not include a person who needs special consideration, "No" is registered in the "Whether there are people who need special consideration" field. This information indicating whether or not there are people who need special consideration is attribute information of evacuee R. Note that the evacuee management table may also register detailed information about people who need special consideration. For example, information indicating whether a person who needs special consideration is a pregnant woman, infant, young child, elderly person, disabled person, or sick person may be registered.

In the transportation method field, information on the transportation method used by evacuee R corresponding to the evacuee ID when evacuating is registered. For example, information such as "walking," "private car," and "public transportation" is registered in the transportation method field. This information on transportation method is attribute information of evacuee R.

The priority rank of the evacuee R corresponding to the evacuee ID is registered in the priority rank field. This ranking is based on the current location and attribute information of the evacuee R. Evacuees are ranked from "A" to "D" in descending order of priority, and the determined rank is registered in the priority rank field.

The evacuation site ID field registers the evacuation site ID of the evacuation site E for which the reservation of evacuee R corresponding to the evacuee ID has been accepted.

The evacuation start time field registers the optimal evacuation start time (evacuation timing) for evacuee R corresponding to the evacuee ID to evacuate to evacuation site E.

The evacuation completion time field registers the optimal evacuation completion time (evacuation timing) when evacuee R corresponding to the evacuee ID arrives at the evacuation site E.

As shown in FIG. 6, an emergency email is delivered from the evacuation support system 1 to the smartphone 6 of the evacuee R in the event of an emergency. The emergency email screen displayed on the display 44 of the smartphone 6 displays emergency information indicating the occurrence of an emergency, and also has a selection input section 45 that asks whether or not the evacuee R wishes to receive assistance with evacuation guidance. If the evacuee R wishes to receive assistance with evacuation guidance, he or she selects "Yes," and if not, he or she selects "No."

As shown in FIG. 7, an attribute information input form (attribute information input screen) is displayed on the display 44 of the smartphone 6 of evacuee R who has selected to request assistance with evacuation guidance. The attribute information can be input using the pull-down menus 46 provided for each question item.

As shown in FIG. 8, a list of candidate evacuation sites E to which evacuee R can evacuate (evacuation site reservation screen) is displayed on the display 44 of the smartphone 6 of the evacuee R who has entered the attribute information. This screen is provided with a selection input unit 47 that displays a map of the evacuation site E corresponding to the candidate evacuation site E. Note that an evacuation route to the evacuation site E may be displayed together with the map. Furthermore, this screen is provided with a selection input unit 48 for applying to reserve the evacuation site E. Also, a selection input unit 49 is provided in the case where a candidate evacuation site E will not be used. Evacuee R can use this screen to apply for a reservation for the evacuation site E that he or she wishes to use. If there are multiple candidate evacuation sites E, he or she can apply to reserve multiple evacuation sites E.

After the reservation for evacuation site E is accepted, potential evacuation routes from the current location to evacuation site E are displayed on the display 44 of the smartphone 6 of the evacuee R. The evacuee R selects the evacuation route to use from the list of potential evacuation routes.

As shown in FIG. 9, an evacuation timing presentation screen is displayed on the display 44 of the smartphone 6 of evacuee R, whose reservation has been accepted and who has selected an evacuation route. This screen displays the name of the evacuation site E, whose reservation has been accepted, as well as the evacuation start time and evacuation completion time. This screen is provided with a selection input unit 50 that displays the evacuation route. If evacuee R begins evacuation at the evacuation start time, he or she can arrive at the evacuation site E at the evacuation completion time.

The evacuation start time and evacuation completion time may change. For example, the evacuation completion time may be delayed due to changes in traffic information. In addition, the evacuation start time and evacuation completion time may be updated along with updates to weather information or radiation information.

Next, the evacuation support processing executed by the evacuation support system 1 will be explained using the flowchart in FIG. 10. Note that the block diagrams shown in FIG. 2 to FIG. 3 will be referred to as appropriate. The following steps are at least a part of the processing included in the evacuation support processing, and other steps may also be included in the evacuation support processing.

The evacuation support process is a process that is repeated at regular intervals. By repeating this process, the evacuation support method is executed in the evacuation support system 1. Note that this process may be executed as an interrupt while the evacuation support system 1 is executing another main process.

As shown in FIG. 10, first, in step S11, the main control unit 11 of the evacuation support system 1 executes evacuation site information collection processing. In this evacuation site information collection processing, evacuation site information related to evacuation site E is collected. The collected evacuation site information is stored in the evacuation site database 14.

In the next step S12, the traffic information acquisition unit 16 executes a traffic information collection process. Here, the traffic information acquisition unit 16 acquires traffic information related to roads based on data sent from the traffic control center 4.

In the next step S13, the weather information acquisition unit 17 executes a weather information collection process. Here, the weather information acquisition unit 17 acquires weather information related to the weather based on data sent from the Japan Meteorological Agency 3. Note that the acquired weather information is not limited to the Japan Meteorological Agency 3, and may be acquired from any weather information dissemination organization that disseminates weather information related to the weather. In addition, the collected weather information is stored in the weather environment database 13.

In the next step S14, the radioactivity information acquisition unit 18 executes a radioactivity information collection process. Here, the radioactivity information acquisition unit 18 acquires radioactivity information related to radioactive materials released from the nuclear facility based on data sent from the Japan Meteorological Agency 3. The collected radioactivity information is stored in the meteorological environment database 13.

In the next step S15, the emergency information distribution unit 19 executes an emergency information distribution process. Here, when an emergency occurs, the emergency information distribution unit 19 distributes emergency information indicating the occurrence of an emergency to the smartphone 6 (evacuee terminal) of the evacuee R.

In the next step S16, the main control unit 11 executes the evacuation site determination process (FIG. 11) described below. This process is executed individually for each evacuee ID.

In the next step S17, the main control unit 11 executes the evacuation route determination process (FIG. 12) described below. This process is executed individually for each evacuee ID.

In the next step S18, the evacuation route update unit 36 executes an evacuation route display update process. Here, when an evacuation route is being displayed on the smartphone 6 of the evacuee R, the evacuation route update unit 36 updates the evacuation route used by the evacuee R based on constantly updated traffic information, weather information, radiation information, and the like. The evacuation timing is also updated. In this way, the display 44 of the smartphone 6 of the evacuee R displays the evacuation route and evacuation timing updated based on the latest information. This process is executed individually for each evacuee ID. The evacuation route update unit 36 stores evacuation-related information indicating the updated evacuation route and evacuation timing in the evacuation data accumulation database 15.

In the next step S19, the main control unit 11 executes evacuation location status distribution processing. This processing is executed individually for each evacuee ID.

Here, the image delivery unit 37 delivers an image of the evacuation site E captured by the evacuation site camera device 10 to the smartphone 6 of the evacuee R. For example, when the evacuee R selects an evacuation site E that he or she wishes to use from a list of candidate evacuation sites E, the evacuee R can check an image of the candidate evacuation site E.

In addition, the congestion degree calculation unit 38 calculates the congestion degree of the evacuation site E based on the image of the evacuation site E captured by the evacuation site camera device 10. Then, the congestion degree distribution unit 39 distributes the congestion degree of the evacuation site E displayed as a candidate to the smartphone 6 of the evacuee R.

In the next step S20, the main control unit 11 executes the evacuation timing management process (FIG. 13) described below. This process is executed individually for each evacuee ID.

In the next step S21, the main control unit 11 executes the evacuation site reception management process (FIG. 14) described below. Then, the evacuation support process ends.

Next, the evacuation site determination process will be explained using the flowchart in FIG. 11. This evacuation site determination process is a process for determining an appropriate evacuation site for evacuee R.

As shown in FIG. 11, first, in step S31, the main control unit 11 of the evacuation support system 1 determines whether or not the evacuee R desires evacuation support. This determination is made based on the input operation of the selection input unit 45 of the emergency email (FIG. 6) delivered to the smartphone 6 of the evacuee R. Here, if the evacuee R does not desire evacuation support (NO in step S31), the evacuation site determination process ends. On the other hand, if the evacuee R desires evacuation support (YES in step S31), the process proceeds to step S32.

In step S32, the current position acquisition unit 22 acquires the current position of the evacuee R. For example, the smartphone 6 of the evacuee R acquires its own position using a satellite positioning system, and this position is transmitted to the evacuation support system 1 via the Internet 2. The current position acquisition unit 22 can then acquire the current position of the evacuee R. The current position acquisition unit 22 stores the acquired current position in the evacuation data accumulation database 15.

In the next step S33, the attribute information acquisition unit 23 acquires attribute information of the evacuee R. Here, the attribute information input display unit 20 displays an input form (Figure 7) on the smartphone 6 of the evacuee R, which requests the entry of attribute information. Then, the attribute information input acceptance unit 21 accepts the entry of the attribute information based on the input form. The attribute information acquisition unit 23 stores the acquired attribute information in the evacuation data accumulation database 15. Here, the attribute information is registered in the evacuee management table (Figure 5) in association with the evacuee ID.

In the next step S34, the priority determination unit 24 determines the priority of the evacuee R based on the current location acquired by the current location acquisition unit 22 and the attribute information acquired by the attribute information acquisition unit 23. Here, the evacuee R is ranked according to the priority, and the rank is registered in the evacuee management table (Figure 5) in association with the evacuee ID.

In the next step S35, the evacuation behavior determination unit 25 executes evacuation behavior determination processing. Here, the evacuation behavior determination unit 25 determines the evacuation behavior predicted to be performed by the evacuee R based on the current position acquired by the current position acquisition unit 22 and the attribute information acquired by the attribute information acquisition unit 23.

In the next step S36, the candidate display unit 26 displays candidates for evacuation sites E to which the evacuee R can take refuge on the smartphone 6 used by the evacuee R, based on the evacuation action determined by the evacuation action determination unit 25 and the evacuation site information stored in the evacuation site database 14.

In the next step S37, the evacuation site reservation unit 27 accepts a reservation for the evacuation site E displayed as a candidate from the smartphone 6 used by the evacuee R.

In the next step S38, the reservation decision unit 28 determines whether the priority of the evacuee R whose reservation has been accepted is "A." If the priority is not "A" (NO in step S38), the process proceeds to step S40. On the other hand, if the priority is "A" (YES in step S38), the process proceeds to step S39.

In step S39, the reservation decision unit 28 executes a first-type reservation decision process. This first-type reservation decision process determines whether to accept or reject the reservation. Then, the process proceeds to step S42.

In step S40, the reservation decision unit 28 notifies the smartphones 6 of the evacuees R whose priority is not "A" that they are waiting for a reservation to be decided. For example, the reservation decision waiting notification is sent by email or the like.

In the next step S41, the reservation decision unit 28 executes a second type reservation decision process. This second type reservation decision process determines whether to accept or reject the reservation. Then, the process proceeds to step S42.

The second type reservation determination process is executed after all or a certain number of reservations for evacuees R with a priority of "A" have been determined in the first type reservation determination process. The second type reservation determination process may also be executed after a predetermined time has elapsed. In this way, reservations for evacuees R with a higher priority are determined first.

In addition to the second type reservation determination process, a third type reservation determination process and a fourth type reservation determination process may be provided. For example, the second type reservation determination process determines a reservation for evacuee R with a priority of "B," the third type reservation determination process determines a reservation for evacuee R with a priority of "C," and the fourth type reservation determination process determines a reservation for evacuee R with a priority of "D."

Note that an evacuee R can apply to reserve multiple evacuation sites E. A desired order of priority may be assigned when applying for a reservation. The reservation decision unit 28 may give priority to accepting a reservation for the first desired evacuation site E for an evacuee R with a high priority. For an evacuee R with a low priority, the reservation decision unit 28 may accept a reservation for an evacuation site E that is lower in the order of preference and has fewer applicants. In this way, an evacuee R with a low priority does not need to wait until a reservation for an evacuee R with a high priority has been decided.

In step S42, the reservation decision unit 28 stores reservation information indicating the reservation status in the evacuation data accumulation database 15. For example, the evacuation site ID of the evacuation site E for which the reservation has been accepted is associated with the evacuee ID and registered in the evacuee management table (Figure 5). Then, the evacuation site decision process is terminated.

Next, the evacuation route determination process will be explained using the flowchart in FIG. 12. This evacuation route determination process is a process for determining an appropriate evacuation route for evacuee R.

As shown in FIG. 12, first, in step S51, the main control unit 11 of the evacuation support system 1 determines whether or not the evacuation location E for the evacuee R has been determined. Here, if the evacuation location E for the evacuee R has not been determined (NO in step S51), the evacuation route determination process ends. On the other hand, if the evacuation location E for the evacuee R has been determined (YES in step S51), the process proceeds to step S52.

In step S52, the evacuation route candidate creation unit 31 executes an evacuation route information creation process. Here, the evacuation route candidate creation unit 31 creates candidates for evacuation routes that can be used by the evacuee R based on the information accumulated in the evacuation data accumulation database 15.

In the next step S53, the evacuation route display unit 32 displays the candidate evacuation routes created by the candidate evacuation route creation unit 31 on the smartphone 6 of the evacuee R.

In the next step S54, the evacuation route reception unit 33 receives from the smartphone 6 of the evacuee R whether or not to use the evacuation route displayed as a candidate. This reception determines the evacuation route to be used by the evacuee R.

In the next step S55, the evacuation timing determination unit 34 executes an evacuation timing determination process. Here, the evacuation timing determination unit 34 determines the evacuation timing of the evacuation route to be used by the evacuee R based on the evacuation site information, the current position, attribute information, traffic information, weather information, radiation information, geographic information, etc.

In the next step S56, the evacuation timing display unit 35 displays information indicating the evacuation timing on the smartphone 6 of the evacuee R (Figure 9).

In the next step S57, the main control unit 11 stores the determined evacuation route and evacuation-related information indicating the evacuation timing in the evacuation data accumulation database 15. For example, the evacuation start time and evacuation completion time as the evacuation timing are associated with the evacuee ID and registered in the evacuee management table (Figure 5). Then, the evacuation route determination process is terminated.

Next, the evacuation timing management process will be explained using the flowchart in Figure 13. This evacuation timing management process is a process for managing evacuee R so that he or she can evacuate at the appropriate time.

As shown in FIG. 13, first, in step S61, the current location acquisition unit 22 of the evacuation support system 1 executes a current location acquisition process. Here, the current location acquisition unit 22 acquires the current location of the evacuee R. Note that the current location acquired at this time may not only be the current location when applying to reserve the evacuation site E, i.e., the location of the evacuee R before the evacuation begins, but may also be the location of the evacuee R after the evacuation begins. This current location acquisition process is executed at regular time intervals, and the current location of the evacuee R is updated each time.

In the next step S62, the evacuation timing determination unit 40 refers to the evacuee management table (Figure 5) and obtains the evacuation start time registered in association with the evacuee ID. The evacuation timing determination unit 40 then determines whether the current time is after the evacuation start time. Here, if the current time is not after the evacuation start time (NO in step S62), the process proceeds to step S65. On the other hand, if the current time is after the evacuation start time (YES in step S65), the process proceeds to step S63.

In step S63, the evacuation timing determination unit 40 determines whether the current location of the evacuee R has changed compared to the location at the time of reservation application for the evacuation site E, that is, whether the evacuee R has started evacuation. If the current location has changed (YES in step S63), the evacuation timing management process ends. On the other hand, if the current location has not changed (NO in step S63), the process proceeds to step S64.

In step S64, the warning display unit 41 issues a first type warning notification (evacuation urging notification) to the smartphone 6 of the evacuee R. Here, a notification urging the evacuee R to evacuate is displayed on the display 44 of the smartphone 6 of the evacuee R. Then, the evacuation timing management process is terminated.

In step S65, which is reached if step S62 is NO, the evacuation timing determination unit 40 determines whether the current location of the evacuee R has changed compared to the location at the time of the reservation application for the evacuation site E, that is, whether the evacuee R has begun evacuation. Here, if the current location has not changed (NO in step S65), the evacuation timing management process ends. On the other hand, if the current location has changed (YES in step S65), the process proceeds to step S66.

In step S66, the warning display unit 41 issues a second type warning notification (evacuation postponement notification) to the smartphone 6 of the evacuee R. Here, a notification urging the evacuee R to postpone evacuation is displayed on the display 44 of the smartphone 6 of the evacuee R. Then, the evacuation timing management process is terminated.

In this embodiment, the evacuation support system 1 delivers a warning notification to the smartphone 6 of the evacuee R, but other configurations are also possible. For example, an application that manages the timing of evacuation may be installed on the smartphone 6 of the evacuee R, and a warning notification may be displayed on the smartphone 6 of the evacuee R based on this application.

Next, the evacuation site reception management process will be described using the flowchart in Figure 14. This evacuation site reception management process is a process for determining whether an evacuee R has evacuated to the appropriate evacuation site E at the appropriate time when the manager M of the evacuation site E receives the evacuee R.

As shown in FIG. 14, first, in step S71, the main control unit 11 of the evacuation support system 1 acquires an evacuee ID. Here, the evacuee ID that is input to the smartphone 5 of the manager M is sent. Note that the evacuee ID may also be sent from the smartphone 6 of the evacuee R.

In the next step S72, the main control unit 11 of the evacuation support system 1 acquires the evacuation site ID. Here, the evacuation site ID is sent from the smartphone 5 of the manager M. Note that the ID entered into the smartphone 6 of the evacuee R may also be sent.

In the next step S73, the main control unit 11 executes a process to determine whether or not to accept the evacuee. The decision as to whether or not to accept the evacuee at the evacuation site E may be determined by the main control unit 11, or information that allows the decision as to whether or not to accept the evacuee may be delivered to the smartphone 5 of the evacuee R or the manager M, and the manager M may make the decision based on this information.

For example, the reservation information distribution unit 29 distributes reservation information that can identify whether or not an evacuee R who has arrived at the evacuation site E is a person whose reservation has been accepted, based on information stored in the evacuation data accumulation database 15. In addition, the timing information distribution unit 42 distributes timing information that can identify whether or not an evacuee R who has arrived at the evacuation site E is a person who has evacuated at the determined evacuation timing.

In the next step S74, the reservation information display unit 30 displays the reservation information on the display 44 of the smartphone 5 of the evacuee R or manager M. In addition, the timing information presentation unit 43 displays timing information on the display 44 of the smartphone 5 of the evacuee R or manager M. For example, it displays information indicating whether the evacuee R has reached the reserved evacuation site E, information indicating whether the evacuee R has arrived at the evacuation site E at the appropriate evacuation completion time, information indicating whether the evacuation site has been accepted or rejected, and the like. Then, the evacuation site acceptance management process is terminated.

In the flowchart of this embodiment, an example is shown in which each step is executed in series, but the order of steps is not necessarily fixed, and the order of some steps may be reversed. Also, some steps may be executed in parallel with other steps.

The system of this embodiment includes a control device with a highly integrated processor such as a dedicated chip, FPGA (Field Programmable Gate Array), GPU (Graphics Processing Unit), or CPU (Central Processing Unit), a storage device such as ROM (Read Only Memory) or RAM (Random Access Memory), an external storage device such as HDD (Hard Disk Drive) or SSD (Solid State Drive), a display device such as a display, an input device such as a mouse or keyboard, and a communication interface. This system can be realized with a hardware configuration that uses a normal computer.

The program executed by the system of this embodiment is provided in advance in a ROM or the like. Alternatively, this program may be provided stored in an installable or executable file format on a non-transitory computer-readable storage medium such as a CD-ROM, CD-R, memory card, DVD, or flexible disk (FD).

The programs executed by this system may also be stored on a computer connected to a network such as the Internet and provided by downloading them via the network. This system may also be configured by combining separate modules that independently perform the functions of the components and connect them together via a network or dedicated lines.

The evacuation support system 1 may include a computer equipped with artificial intelligence (AI) that performs machine learning. For example, the following processes may be performed by machine learning: grasping traffic conditions, determining future evacuation behavior of evacuee R, extracting candidate evacuation sites E, creating candidate evacuation routes, determining the timing of evacuation, and calculating the degree of congestion at evacuation sites E. The evacuation support system 1 may also include a deep learning unit that extracts a specific pattern from multiple patterns based on deep learning.

Analysis techniques based on artificial intelligence learning can be used for the computer-based analysis of this embodiment. For example, learning models generated by machine learning using neural networks, learning models generated by other machine learning, deep learning algorithms, regression analysis, and other mathematical algorithms can be used. In addition, forms of machine learning include clustering, deep learning, and other forms.

The system of this embodiment includes a computer equipped with artificial intelligence that performs machine learning. For example, the system may be configured with one computer equipped with a neural network, or may be configured with multiple computers equipped with neural networks.

Here, a neural network is a mathematical model that represents the characteristics of brain functions through computer simulation. For example, this model shows that artificial neurons (nodes) that form a network through synaptic connections change the strength of synaptic connections through learning, and acquire problem-solving abilities. Furthermore, neural networks acquire problem-solving abilities through deep learning.

For example, a neural network is provided with an intermediate layer having six layers. Each intermediate layer is made up of 300 units. Furthermore, by having the multi-layered neural network learn in advance using training data, it is possible to automatically extract features from patterns of changes in the state of a circuit or system. Note that for the multi-layered neural network, the number of intermediate layers, number of units, learning rate, number of times of training, and activation function can be set on the user interface.

In addition, deep reinforcement learning may be used in the neural network, in which a reward function is set for each information item to be learned, and the information item with the highest value is extracted based on the reward function.

For example, we use a CNN (Convolution Neural Network), which has a proven track record in image recognition. In this CNN, the intermediate layer is composed of a convolution layer and a pooling layer. The convolution layer obtains a feature map by applying filtering to nearby nodes in the previous layer. The pooling layer further reduces the feature map output from the convolution layer to create a new feature map. At this time, by obtaining the maximum value of the pixels contained in the area of interest in the feature map, it is possible to absorb slight deviations in the position of the feature amount.

The convolutional layer extracts local features from an image, and the pooling layer consolidates local features. These processes reduce the size of the input image while maintaining its features. In other words, CNN can significantly compress (abstract) the amount of information contained in an image. Then, the input image can be recognized and classified using the abstracted image image stored in the neural network.

Note that there are various methods for deep learning, such as autoencoder, recurrent neural network (RNN), long short-term memory (LSTM), and generative adversarial network (GAN). These methods may be applied to the deep learning of this embodiment.

In this embodiment, various devices such as home appliances 7 or car navigation systems 8 can be used as evacuee terminals, not just smartphones 6. In this way, not only local residents but also temporary visitors such as travelers can easily connect to the evacuation support system 1. This makes it possible to shorten the time it takes to complete evacuation. In addition, by distributing the occurrence of a disaster via television to elderly people and residents who do not have mobile devices, evacuation guidance can be swiftly provided, improving the rescue rate.

In this embodiment, the mobile device may be a smartphone 6. Furthermore, the vehicle-mounted device may be a car navigation system 8 or a drive recorder 9. In this way, when the road that the evacuee R took to evacuate becomes impassable due to the effects of a disaster, the information can be input to the smartphone 6 or the car navigation system 8 and transmitted to the traffic control center 4. Furthermore, the image of the drive recorder 9 can be transmitted to the traffic control center 4. In this way, a safe and quick evacuation route can be presented. This allows the evacuee R to evacuate safely and shortens the time required for evacuation. Furthermore, since danger during the evacuation can be avoided, the rescue rate can be improved. Note that the information obtained by the mobile device or the vehicle-mounted device may be directly transmitted to the evacuation support system 1.

In this embodiment, the attribute information is acquired in an emergency, but other configurations are also possible. For example, during normal times, local residents register attribute information such as their date of birth, sex, family structure, whether or not they have any chronic illnesses, and the means of transportation they will use in an evacuation with a local government agency. Then, in an emergency, it may be possible to reserve evacuation site E using the attribute information that has already been registered.

In this embodiment, the priority of the evacuees R is categorized by rank, but other configurations are also possible. For example, the priority of the evacuees R may be categorized by points.

In this embodiment, a time difference is provided between the reservation of a high-priority evacuee R and a low-priority evacuee R, but other configurations are also possible. For example, if there is no competition between the evacuation sites E that evacuees wish to reserve, the reservation of a low-priority evacuee R may be determined before the reservation of a high-priority evacuee R.

It is also possible to identify evacuees R who may be infected with a specific infectious disease that is highly contagious, such as airborne or droplet infection, based on attribute information, and to evacuate such evacuees R to a specific evacuation site E. For example, the input form for attribute information may request input of information indicating whether or not the evacuees have a fever, and if they have a fever, the priority may be set to "S" rank. Then, a specific evacuation site E that has appropriate facilities that can be used by this "S" rank evacuee R may be reserved. In addition, the evacuees may be guided to this evacuation site E. In other words, the priority ranking in this embodiment includes not only a mode of separating high and low, but also a mode of separating evacuees R with special circumstances from other evacuees R. Furthermore, even in a general evacuation site E, when the manager M accepts evacuees R, the evacuees R with "S" rank may be separated from other evacuees R and accepted.

According to the embodiment described above, by providing an evacuation data accumulation database that stores evacuee identification information that can individually identify evacuees and evacuation sites for which reservations have been accepted, it is possible to reserve an appropriate evacuation site according to the situation of the evacuee.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, modifications, and combinations can be made without departing from the spirit of the invention.
