Description

This disclosure relates to an information processing system, an information processing method, and an information processing program.

Technologies have been proposed to improve convenience for drivers of vehicles that transport passengers, such as taxis. For example, Patent Document 1 discloses a system that provides taxi drivers with information about areas where passengers are likely to board.

Japanese Patent Application Laid-Open No. 2014-130552

The risks borne by drivers may vary depending on the departure and destination (pick-up and drop-off locations), etc. For example, there may be a high frequency of troubles, such as non-payment of fares, between passengers departing from a particular area. It is desirable to assess risks so that they are identified in advance.

One aspect of the present disclosure provides an information processing system, information processing method, and information processing program capable of assessing risks that may occur to a driver.

An information processing system according to one aspect of the present disclosure includes a processing unit that evaluates, for each location, the risks that may arise for a driver of a vehicle transporting a passenger user based on a plurality of pieces of input information, each piece of input information being associated with location information and time information. The plurality of pieces of input information include vehicle information and user information. The vehicle information includes at least one of the driver's attributes, vehicle operation information, and detection information from a sensor installed in the vehicle. The user information includes at least one of the user's attributes, usage history of vehicle transportation services, and payment information.

An information processing method according to one aspect of the present disclosure is an information processing method that includes an information processing device evaluating, for each location, the risks that may arise for the driver of a vehicle transporting a passenger user, based on a plurality of pieces of input information, each of which is associated with location information and time information, wherein the plurality of pieces of input information include vehicle information and user information, the vehicle information including at least one of driver attributes, operation information, and sensor detection information, and the user information including at least one of user attributes and vehicle usage history.

An information processing program according to one aspect of the present disclosure is an information processing program that causes a computer to evaluate, for each location, the risks that may arise for drivers of vehicles transporting passenger users, based on a plurality of pieces of input information, each of which is associated with location information and time information, wherein the plurality of pieces of input information include vehicle information and user information, the vehicle information including at least one of driver attributes, operation information, and sensor detection information, and the user information including at least one of user attributes and vehicle usage history.

Embodiments of the present disclosure will be described in detail below with reference to the drawings. Note that in each of the following embodiments, identical elements will be designated by the same reference numerals, and duplicate descriptions will be omitted.

The present disclosure will be described in the following order:
1. Introduction 2. Embodiment 3. Effects

1. Introduction For example, the risks involved in a taxi are different when it picks up a passenger from home to work (such as an office) and when it picks up a casual passenger in a busy shopping district. There are cases where passengers who pick up passengers at certain locations frequently skip out on the fare. By the time fraudulent credit card use is discovered or recognized as a crime, considerable damage has already been done, and there will be no small amount of damage.

The disclosed technology provides, for example, risk sharing and assessment tools for pick-up and drop-off locations for taxi operators. For example, risk assessments are performed based on customer attributes, pick-up locations, etc. by evaluating accumulated past data. Examples of assessment results include mileage by location and time period, frequency of use, and fare collection rate, which may be anonymized and indexed and shared and provided to taxi operators. By calculating risk in advance, for example, female drivers and novice drivers may be discouraged from picking up and dropping off passengers in dangerous locations (places with poor security). Taxi companies may also make preparations such as activating dashcams or setting the drive recorder's storage period to a longer period. In addition to human factors, traffic accidents and other factors may also be taken into account as risk indicators. Risk assessments may be used in a variety of ways, including but not limited to these.

2. Embodiment Fig. 1 is a diagram illustrating an example of a schematic configuration of an information processing system according to an embodiment. The information processing system 100 includes a user terminal 1, an information processing device 2, and a vehicle dispatch management device 3. These terminals and devices are connected to a network N. The user terminal 1 may be a plurality of user terminals 1.

Figure 1 also illustrates multiple vehicles V. Vehicle V is an example of a means of transportation. An example of a vehicle V as a means of transportation is a taxi. The following describes the case where vehicle V is a taxi. Note that the number of vehicles V is not limited to the example shown in Figure 1.

For example, vehicle V is equipped with an on-board device and a terminal device (not shown). The on-board device acquires necessary data from a fare meter, a GPS (Global Positioning System) receiver, a gyro sensor, a speedometer, etc., and generates vehicle information representing a movement log of vehicle V. In addition to sensors such as a GPS receiver, sensors such as a drive recorder are also included in the on-board device. The vehicle information includes the business area, a status indicating the business status (e.g., "occupied vehicle," "empty vehicle," "pick-up," etc.), a fare (fare), a current location, a travel speed, and a travel direction. The vehicle information also includes an ID. Examples of IDs include a company ID identifying the company to which vehicle V belongs, a wireless ID identifying vehicle V, and a crew ID identifying the driver of vehicle V. Other information that may be included in the vehicle information include a status time indicating the time the status was generated. Driver attributes, operation information, and sensor detection information are also included in the vehicle information, which will be described later with reference to FIG. 3. The on-board device generates vehicle information, for example, at a predetermined interval, and transmits it to the vehicle dispatch management device 3.

Examples of terminal devices provided in vehicle V include smartphones, tablet terminals, etc. capable of running a driver application. The terminal device can communicate with the vehicle dispatch management device 3 by being connected to the network N, for example, via an access point AP (base station, etc.). The driver application presents (displays, etc.) information regarding the dispatch of vehicle V to the driver and accepts operations from the driver. For example, it presents dispatch request information to the driver and sends a response to the dispatch request information to the vehicle dispatch management device 3. The dispatch request information includes information such as the route (including the departure point and destination), departure time, arrival time, fare, etc.

In this example, the user terminal 1 is a smartphone, tablet terminal, etc., and is connected to the network N via an access point AP (base station, etc.). A user (not shown) of the user terminal 1 operates the user terminal 1 and uses an application for reserving (dispatching) a vehicle V, etc., to use the services of the information processing system 100. Note that the number of user terminals 1 is not limited to the example shown in Figure 1.

The information processing device 2 executes various processes necessary for using the services of the information processing system 100. Some of the processes may be performed in cooperation with the vehicle dispatch management device 3. The vehicle dispatch management device 3 constitutes a vehicle dispatch management system operated, for example, by a taxi company. Note that in the embodiment, an example is described in which the information processing device 2 and the vehicle dispatch management device 3 are separate devices, but the functions of the information processing device 2 and the vehicle dispatch management device 3 may be realized by a single device, or by three or more devices. In the former case, for example, the functions of the vehicle dispatch management device 3 may be incorporated into the information processing device 2.

Figure 2 is a diagram showing an example of functional blocks of an information processing system. Several representative functional blocks in the user terminal 1, information processing device 2, and vehicle dispatch management device 3 are illustrated.

The user terminal 1 includes a communication unit 11 and an application unit 12. The communication unit 11 transmits and receives various information necessary for processing executed on the user terminal 1 to and from the information processing device 2. Unless otherwise specified, the transmission and reception of information by the user terminal 1 hereinafter refers to the transmission and reception of information by the communication unit 11.

The application unit 12 is a processing unit for executing applications. The application is an application for reserving a vehicle V, and is realized in cooperation with the application unit 22 of the information processing device 2 described below. In the user terminal 1, the application unit 12 also provides a user interface that accepts user operations by user U1 and presents information to user U1. Hereinafter, unless otherwise specified, the acceptance of user operations and the presentation of information by the user terminal 1 refers to the acceptance of user operations and the presentation of information by the application unit 12.

The application unit 12 accepts input of reservation information. The reservation information includes information such as the departure and destination (pick-up and drop-off location), departure time, and arrival time. The user terminal 1 transmits the reservation information to the information processing device 2. The application unit 12 also transmits user information to the information processing device 2. The user information includes user attributes, usage history, payment information, etc., which will be explained later with reference to Figure 3.

The information processing device 2 includes a communication unit 21, an application unit 22, and a memory unit 23.

The communication unit 21 transmits and receives information necessary for the processing performed by the information processing device 2 between the user terminal 1 and the vehicle dispatch management device 3. Unless otherwise specified, the transmission and reception of information by the information processing device 2 below refers to the transmission and reception of information by the communication unit 21.

The application unit 22 is a processing unit for executing the above-mentioned applications. The application unit 22 includes an information acquisition unit 221, a risk assessment unit 222, a map generation unit 223, and a dispatch request information generation unit 224. In addition to these, the application unit 22 also uses the communication unit 21 and the memory unit 23 to execute the applications. Details will be explained again later.

The memory unit 23 stores various information used by the information processing device 2. One example of the stored information is the program 23a. The program 23a is an information processing program (software) that causes a computer to function as the information processing device 2. Hereinafter, unless otherwise specified, the storage of information by the information processing device 2 refers to the storage of information by the memory unit 23.

The vehicle dispatch management device 3 is a device operated, for example, by a taxi company to manage the dispatch of vehicles V. The vehicle dispatch management device 3 includes a communication unit 31 and a vehicle dispatch management unit 32.

The communication unit 31 transmits and receives various information necessary for the dispatch management of the vehicle V between the information processing device 2 and the vehicle V. Unless otherwise specified, the transmission and reception of information by the dispatch management device 3 below refers to the transmission and reception of information by the communication unit 31.

The vehicle allocation management unit 32 manages vehicle information for each of the multiple vehicles V and allocates the vehicles V. Details will be provided later.

We will now explain the application unit 22 of the information processing device 2 again. The information acquisition unit 221 acquires and stores (accumulates) various indicators that indicate the risks that may occur to the driver of the vehicle V as input information.

Figure 3 is a diagram showing examples of input information. Examples of input information include vehicle information, user information, and external information. Each piece of input information is associated with location information. The input information may also be associated with time information.

Vehicle information includes driver attributes, operation information, and sensor detection information. Driver attributes are the attributes of the driver of vehicle V, including age, gender, years of experience, etc. Operation information includes operation information of vehicle V, including location information on the driving route, whether or not there have been any accidents during driving, near misses, non-payment of tolls, fraudulent use of credit cards, etc. Sensor detection information includes detection information from sensors installed in the vehicle, such as the drive recorder mentioned above.

Vehicle information is acquired, for example, by a driver application running on a terminal device of vehicle V and transmitted to the vehicle dispatch management device 3. The driver's manual operation may be involved in the acquisition of vehicle information by the driver application. The vehicle dispatch management device 3 transmits the vehicle information to the information processing device 2. The information acquisition unit 221 acquires the vehicle information.

User information includes user attributes, usage history, and payment information. User attributes include birthdate, age, occupation, job title, and other registered information (the content of optional registered information such as workplace, and whether it is listed). Usage history is the usage history of transportation services using vehicle V (which can also be considered the usage history of the application), and includes, for example, information about vehicle V, information about the route, etc. Payment information includes whether the fee for vehicle V (usage fee) has been paid, etc.

User information is acquired, for example, by an application running on the user terminal 1 and transmitted to the information processing device 2. The information acquisition unit 221 acquires the user information. User operation may be involved in the acquisition of user information by the application.

We will now discuss payment information among the external information. Payment information includes payment information for each user and/or each operation, such as information on whether or not a card payment was properly debited. Such payment information is provided, for example, by a payment service provider and acquired by the information acquisition unit 221.

The following describes accident information, congestion information, and construction information, which are types of external information. Accident information includes the location and time of the traffic accident, and the details of the traffic accident (such as the type of accident). Congestion information includes the location and time of the congestion, and the details of the congestion (such as the level of congestion). Construction information includes the location and time of the construction work, and the details of the construction work (such as the type of construction work). Such accident information, etc. is provided, for example, by a traffic information bureau, and acquired by the information acquisition unit 221.

This section will discuss event information, disaster occurrence information, and crime occurrence information among the external information. This includes event information, disaster occurrence information, and crime occurrence information. Event information includes the location of the event, the time of occurrence, the content of the event, and the number of attendees. Disaster occurrence information includes the location of the disaster, the time of occurrence, and the content of the disaster (such as the type of disaster). Infectious diseases may also be treated as a type of disaster. Crime occurrence information includes the location of the crime, the time of occurrence, and the content of the crime (such as the severity of the crime). Such event information, etc. is provided, for example, by various websites, and is acquired by the information acquisition unit 221.

For example, various input information such as those described above is acquired by the information acquisition unit 221 at appropriate times and stored (accumulated) in the information processing device 2.

Returning to Figure 2, the risk assessment unit 222 assesses the risk that may occur to the driver of vehicle V for each location based on multiple pieces of input information acquired by the information acquisition unit 221. An example of risk assessment is the calculation of a risk value that indicates the magnitude of the risk.

An example of a method for calculating risk values will be described. In one embodiment, the risk assessment unit 222 calculates a risk value (partial risk value) corresponding to each piece of input information for each location. For example, a table correlating input information with partial risk values is stored in the memory unit 23, and the risk assessment unit 222 calculates the partial risk value by referring to the table.

Furthermore, the risk assessment unit 222 calculates a risk value for each location based on the calculated partial risk values. For example, the risk assessment unit 222 calculates the risk value by adding the partial risk values. In doing so, the risk assessment unit 222 may weight each partial risk value before adding them. Weighting may be performed by multiplying each partial risk value by a weighting coefficient. For example, weighting may be performed so that the weighting coefficient corresponding to the partial risk value of input information (first input information) indicating risk to life or health is greater than the weighting coefficient corresponding to the partial risk value of input information (second input information) indicating financial risk. Examples of input information indicating risk to life or health include operation information (accidents, near misses, etc.), sensor detection information, accident information, disaster occurrence information, and crime occurrence information. Examples of input information indicating financial risk include operation information (non-payment of tolls, etc.) and payment information.

Further weighting may be applied between input information indicating life/physical risks. For example, the greater the danger to life of input information, the larger the corresponding weighting coefficient may be set. Further weighting may be applied between input information indicating financial risks. For example, the greater the risk of financial loss of input information, the larger the corresponding weighting coefficient may be set.

Note that any method capable of risk assessment based on multiple pieces of input information may be used, not limited to the above examples. The risk assessment unit 222 may assess risk using a trained model. The trained model is generated using training data so that, when multiple pieces of input information are input, a risk assessment result is output.

The risk assessment unit 222 may assess risk not only for each location but also for each of various conditions. Examples of conditions include time divisions (date and time, time period, weekday or holiday, etc.), the presence and type of event, driver attributes, etc. The risk assessment unit 222 may also assess risk for each risk item. Examples of risk items include fees (fare default, credit card fraud, etc.), risk level (public safety, traffic accidents, etc.), etc. Not limited to these, various conditions and risk items may be used. For example, it is possible to assess the risk that a user who boards a vehicle from a location where a specific event (such as Halloween) occurs late at night on a holiday on which the event occurs is at high risk of soiling.

Returning to Figure 2, the map generation unit 223 generates a risk map based on the evaluation results (risk assessment results) of the risk assessment unit 222. The risk map is a map that displays locations and risks in association with each other.

Figures 4 to 6 show examples of risk maps. In the example shown in Figure 4, the risk map is displayed in heat map format. The risk for each location is indicated by color (e.g., red). The darker the color (e.g., the redder the location), the higher the risk.

In the examples shown in Figures 5 and 6, the risk map is presented in grid map format. In the example shown in Figure 5, the map is divided into multiple locations, and the risk for each location is represented by color and a risk value. For example, a darker color and a higher risk value indicate a higher risk. In the example shown in Figure 6, no risk value is displayed, and the risk for each location is represented by color.

The map generation unit 223 transmits the generated risk map to vehicle V via the vehicle dispatch management device 3. The driver's application running on the terminal device of vehicle V presents the risk map, allowing the driver of vehicle V to understand the risks at each location. The driver's application may also have the functions of the map generation unit 223. In this case, the evaluation results of the risk assessment unit 222 may be transmitted to vehicle V.

As mentioned above, risk can be evaluated not only for each location but also for various conditions, so the risk map may also display risk in a manner that corresponds to the conditions. Using driver attributes as an example of a condition, the risk map may display risks that apply to an average driver. An example of an average driver is a virtual driver with the attributes of an average driver. The risk map may also display risks that apply to a specific driver. An example of a specific driver is the driver (a real driver) of vehicle V who is actually checking the risk map. For example, in the case of a veteran with no accidents or violations, risks that do not take traffic risk into account may be displayed.

Returning to Figure 3, the dispatch request information generation unit 224 generates dispatch request information based on the reservation information. The dispatch request information is transmitted to the dispatch management device 3. At that time, the risk assessment results (risk map, etc.) are also transmitted to the dispatch management device 3.

The vehicle dispatch management unit 32 of the vehicle dispatch management device 3 will now be described again. The vehicle dispatch management unit 32 dispatches a vehicle V in accordance with the dispatch request information. For example, the vehicle dispatch management unit 32 extracts a vehicle V that can meet the conditions of the dispatch request information based on the vehicle information, and transmits the dispatch request information to the vehicle V. In the vehicle V, as previously described with reference to Figure 1, the driver's app presents the dispatch request information and transmits a response to the vehicle dispatch management device 3. Note that the vehicle dispatch management by the vehicle dispatch management unit 32 may involve manual operation by an operator.

The above-mentioned vehicle V may be extracted by selecting a driver according to the risk assessment results. For example, if the route includes a location with a high risk value, a vehicle V driven by a driver with high risk response capabilities (such as an experienced driver) may be selected. A driver may also be selected individually depending on specific risk items, etc. For example, if the route includes an area where accidents are frequent, a driver with high driving skills may be selected based on past driving information, and a dispatch request may be sent to that driver's vehicle V. A vehicle V may also be selected based on the facilities of the vehicle V, etc. For example, if the dispatch request is for a facility where a cluster outbreak of an infectious disease has been reported as a pick-up or drop-off location, a vehicle V equipped with infectious disease prevention facilities may be selected.

The vehicle dispatch management unit 32 may modify the vehicle dispatch request information before sending it to the vehicle V. The vehicle dispatch request information may be modified based on the risk assessment results. The vehicle dispatch management unit 32 modifies the vehicle dispatch request information so as to reduce the risk.

Examples of modifying dispatch request information include selecting a route based on the risk assessment results and setting a fare based on the risk assessment results. For example, if a high-risk location is included in the route, the dispatch management unit 32 modifies the route to bypass that location. The dispatch management unit 32 may also modify the fare. For example, if a high-risk pick-up or drop-off location is included in the route, the dispatch management unit 32 modifies the fare to make it higher (add on to the fare).

The user may be allowed to choose between amending the route and adding a fare. For example, the dispatch management unit 32 transmits information about the amended route to the user terminal 1 via the information processing device 2 so that the amended route is presented to the user. If the user accepts this, the route amendment is accepted. If the user does not accept the amended route, information about the fare surcharge is presented to the user, for example, along with the reason for this. If the user accepts this, the fare surcharge is selected.

Figure 7 is a flowchart showing an example of processing (information processing method) executed in the information processing system. "Information processing device 2, etc." refers to the information processing device 2 and the vehicle dispatch management device 3. "External information bureau" refers to the payment service provider, traffic information bureau, website, etc., which are sources of external information as previously described with reference to Figure 3.

In step S1, the information processing device 2 acquires vehicle information from the vehicle V. Examples of vehicle information are as described above with reference to Figure 3.

In step S2, the information processing device 2 acquires user information from the user terminal 1. Examples of user information are as described above with reference to Figure 3.

In step S3, the information processing device 2 acquires external information from an external information agency. Examples of external information are as described above with reference to Figure 3.

The processing of steps S1 to S3 described above may be performed as appropriate, thereby storing each piece of information in the information processing device 2.

In step S4, weighting is applied to each piece of input information. The risk assessment unit 222 weights the partial risk values of each piece of input information sent (acquired) in the previous steps S1 to S3, and calculates the risk value for each location by adding them up, etc.

In step S5, a risk map is created. The map generation unit 223 generates a risk map based on the risk assessment results from the previous step S4.

In step S6, reservation information is transmitted. Reservation information is input by user operation at the user terminal 1. The user terminal 1 transmits the reservation information to the information processing device 2.

In step S7, vehicle dispatch request information is generated. The vehicle dispatch request information generation unit 224 generates the vehicle dispatch request information based on the reservation information transmitted in the previous step S6. The vehicle dispatch management unit 32 selects a vehicle V (driver) or modifies the vehicle dispatch request information based on the risk assessment results, such as the risk map generated in the previous step S5.

In step S8, a vehicle dispatch request is made. The vehicle dispatch management unit 32 transmits the vehicle dispatch request information generated in the previous step S7 or the modified vehicle dispatch request information to vehicle V.

In step S9, acceptance is performed. The driver of vehicle V uses the driver application to accept the dispatch request sent in the previous step S8. The acceptance result is sent to the dispatch management device 3.

Although not shown, the vehicle dispatch management device 3 then transmits information indicating that the vehicle dispatch request has been completed to the information processing device 2. The information processing device 2 transmits information indicating that the vehicle dispatch request has been completed to the user terminal 1, and the user terminal 1 presents the information to the user. The vehicle V begins operating based on the vehicle dispatch request information.

Figure 8 is a block diagram showing an example of the hardware configuration of a user terminal, an information processing device, and a vehicle dispatch management device. The functions of the user terminal 1, information processing device 2, and vehicle dispatch management device 3 described above can be realized by installing various programs on a computer. For example, the functions of the information processing device 2 are realized by installing the program 23a shown in Figure 2 described above on a computer. In the computer, a CPU (Central Processing Unit) 201, ROM (Read Only Memory) 202, and RAM (Random Access Memory) 203 are interconnected by a bus 204.

An input/output interface 205 is further connected to the bus 204. An input unit 206, an output unit 207, a memory unit 208, a communication unit 209, and a drive 210 are connected to the input/output interface 205.

The input unit 206 consists of operation buttons, a keyboard, a mouse, a microphone, a touch panel, an input terminal, etc. The output unit 207 consists of a display, a speaker, an output terminal, etc. The storage unit 208 consists of a hard disk, a RAM disk, a non-volatile memory, etc. The communication unit 209 consists of a network interface, etc. The drive 210 drives a removable recording medium 211 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory.

In a computer configured as described above, the CPU 201 performs the above-described series of processes by, for example, loading a program stored in the storage unit 208 into the RAM 203 via the input/output interface 205 and bus 204 and executing it. The RAM 203 also stores data necessary for the CPU 201 to execute various processes as appropriate.

The program executed by the computer (CPU 201) can be provided, for example, by recording it on a removable recording medium 211 such as a packaged medium. The program can also be provided via a wired or wireless transmission medium such as a local area network, the Internet, or digital satellite broadcasting.

In a computer, a program can be installed in the storage unit 208 via the input/output interface 205 by inserting the removable recording medium 211 into the drive 210. The program can also be received by the communication unit 209 via a wired or wireless transmission medium and installed in the storage unit 208. Alternatively, the program can be pre-installed in the ROM 202 or the storage unit 208.

Some examples of other usage aspects of the information processing system 100 are described below.

The input information is not limited to the example described above with reference to Figure 3. Operation management information, payment information, etc. held by the operating company of vehicle V (such as a taxi company) may also be used as input information. Vehicle information may be provided by the operating company.

Drivers may be given the authority to approve a ride request before accepting it. In this case, the driver can decide whether to accept it or not, taking into account the risk assessment results. The driver application may have the functionality to make such a decision. Authority may be given only to inexperienced drivers (e.g., those with less than one year of experience).

The risk assessment results may also be provided to general drivers other than the driver of vehicle V. The application may have the functionality to provide such information.

The risk assessment results may be provided to insurance companies. Insurance companies can calculate insurance premiums based on the risk assessment results. For example, they may charge higher premiums to drivers who frequently drive through high-risk areas.

It can also be applied to ride-sharing. In this case, in addition to life and physical risks, the presence of passengers with bad manners may also be included as a risk item. Information about manners may be obtained from detection information from in-vehicle sensors.

The input information may include not only crimes such as running away from a taxi and taxi robbery, but also general crimes (crimes that occur outside of a vehicle). Such information may be obtained, for example, from the web.

The risk map may be a dynamic map that is dynamically transformed in combination with real-time traffic information, etc.

From the perspective of information protection, etc., at least a portion of the input information may be anonymized and then acquired by the information acquisition unit 221.

3. Effects The information processing system 100 described above can be specified, for example, as follows. As described with reference to Figures 1 to 3, the information processing system 100 includes a processing unit (application unit 22) that evaluates, for each location, the risks that may occur to the driver of a vehicle V transporting a user who is a passenger, based on a plurality of pieces of input information, each of which is associated with location information and time information. The plurality of pieces of input information include vehicle information and user information, where the vehicle information includes at least one of the driver's attributes, vehicle operation information, and detection information from a sensor installed in the vehicle, and the user information includes at least one of the user's attributes, usage history of a vehicle transportation service, and payment information. This makes it possible to evaluate the risks that may occur to the driver.

As explained with reference to Figure 3 etc., the multiple pieces of input information include external information, which may include at least one of payment information, accident information, traffic congestion information, construction information, event information, disaster occurrence information, and crime occurrence information. Such external information can also be used to assess risk.

As described with reference to Figures 3 to 6, the processing unit may generate a risk map showing the risk assessment results. For example, the risk assessment results can be presented in this manner.

The processing unit may assess risk by weighting each of the multiple pieces of input information. The input information includes first input information indicating life and physical risk and second input information indicating financial risk, and the processing unit may weight the first input information more heavily than the second input information. For example, risk can be assessed by weighting in this manner.

As explained with reference to Figure 2 etc., the information processing system 100 may be provided with a vehicle dispatch management unit 32 that dispatches a vehicle V based on the risk assessment results. Dispatching a vehicle V by the vehicle dispatch management unit 32 may include selecting a driver in accordance with the risk assessment results. Dispatching a vehicle by the vehicle dispatch management unit 32 may include selecting a route in accordance with the risk assessment results. Dispatching a vehicle V by the vehicle dispatch management unit 32 may include setting a fee in accordance with the risk assessment results. For example, in this way, vehicle dispatch can be performed that includes risk response.

The information processing method described with reference to Figure 7 etc. is also one aspect of the present disclosure. The information processing method includes an information processing device 2 evaluating, for each location, the risks that may pose to the driver of a vehicle V transporting a passenger user, based on a plurality of pieces of input information, each of which is associated with location information and time information (e.g., steps S4 and S5), where the plurality of pieces of input information include vehicle information and user information, the vehicle information including at least one of driver attributes, operation information, and sensor detection information, and the user information including at least one of user attributes and vehicle usage history. This makes it possible to evaluate the risks that may pose to the driver.
