JP7600843B2 - Boarding location setting method and boarding location setting device - Google Patents

Description

The present invention relates to a boarding location setting method and device for setting the boarding location of a service vehicle dispatched in response to a boarding request from a user.

Conventionally, Patent Document 1 discloses an information processing system that provides users with alternative routes that avoid using crowded stations. The information processing system disclosed in Patent Document 1 obtains congestion information for candidate stations, and if the candidate station is crowded, obtains an alternative route that uses an alternative station.

JP 2016-80665 A

However, conventional information processing systems do not take into account the risk of contracting an infectious disease, even if crowded stations are avoided, so there is a possibility that people at high risk of developing severe symptoms if infected with an infectious disease may end up being mixed with people at high risk of already being infected with the infectious disease. This poses the problem that people at high risk of developing severe symptoms end up increasing their risk of contracting the infectious disease.

The present invention has been proposed in light of the above-mentioned circumstances, and aims to provide a boarding location setting method and device that can prevent people with a high risk of developing severe symptoms from mixing with people with a high risk of infection, thereby reducing the risk of people with a high risk of developing severe symptoms contracting an infectious disease.

In order to solve the above-mentioned problems, a boarding location setting method and device according to one aspect of the present invention calculates a waiting time period during which a user waits to board a service vehicle at multiple candidate boarding locations extracted in response to a boarding request from the user. Then, other users who will use the multiple candidate boarding locations during the waiting time period are extracted, and if a user is at high risk of developing severe symptoms, the extracted other users are determined to be at high risk of infection with an infectious disease. If the other users stay in a facility with a high risk of infection for a predetermined period of time or more during the incubation period of the infectious disease, the other users are determined to be at high risk of infection with an infectious disease. As a result, from among the multiple candidate boarding locations, a candidate boarding location with fewer other users determined to be at high risk of infection with an infectious disease is prioritized and set as the user's boarding location.

In addition, a boarding location setting method and device according to another aspect of the present invention calculates a waiting time period during which a user waits to board a service vehicle at multiple candidate boarding locations extracted in response to a boarding request from the user. If the user stays for a predetermined period of time or more in a facility with a high infection risk during the incubation period of an infectious disease, the user is determined to be a user with a high probability of infection with the infectious disease. Then, other users who use the multiple candidate boarding locations during the waiting time period are extracted, and if the user is determined to be a user with a high probability of infection with the infectious disease, the extracted other users are determined to be at high risk of developing severe symptoms if infected with the infectious disease. As a result, from among the multiple candidate boarding locations, a candidate boarding location with fewer other users with a high risk of developing severe symptoms is preferentially set as the user's boarding location.

The present invention can prevent people at high risk of developing severe symptoms from being mixed with people at high risk of infection, thereby reducing the risk of people at high risk of developing severe symptoms becoming infected with an infectious disease.

An embodiment of the present invention will be described below with reference to the drawings. In the description of the drawings, the same parts are given the same reference numerals and the description will be omitted.

[Vehicle allocation system configuration]
FIG. 1 is a block diagram showing the configuration of a vehicle dispatch system including a boarding location setting device according to the present embodiment. The vehicle dispatch system 1 is a system that dispatches a service vehicle in response to a boarding request from a user. The service vehicle is a vehicle that is dispatched in response to a boarding request from a user, picks up the user at a boarding location, and provides a service of transporting the user to a destination desired by the user. As shown in FIG. 1, the vehicle dispatch system 1 includes a server 10 that manages the dispatch of the service vehicle, a user terminal 20 that the user possesses and requests a boarding in the service vehicle, and an in-vehicle terminal 30 mounted on the service vehicle. The server 10 is connected to the user terminal 20 and the in-vehicle terminal 30 via a wireless or wired network. The network is, for example, the Internet, and may be one that utilizes a mobile communication function such as 5G.

The server 10 manages the dispatch of service vehicles by the dispatch system 1. As shown in FIG. 1, the server 10 includes a communication unit 11, a database 13, and a boarding location setting device 15.

The communication unit 11 has a function of transmitting and receiving information via the network. The communication unit 11 acquires predetermined information, such as a boarding request transmitted from the user terminal 20, via the network, and records the acquired information in the database 13. The communication unit 11 also transmits information, such as the boarding location and travel route, set by the boarding location setting device 15 to the user terminal 20 and the in-vehicle terminal 30 via the network.

The database 13 stores information acquired by the communication unit 11 and information necessary for dispatching a service vehicle. Specifically, the database 13 stores location information and boarding requests acquired from the user terminal 20, as well as user information registered by the user. The database 13 also stores map information, etc., as information necessary for dispatching a service vehicle, including vehicle information, location information, and dispatch plans for the service vehicles. Furthermore, the database 13 also stores information and processing results necessary for the boarding location setting process executed by the boarding location setting device 15. For example, the database 13 also stores information such as the set boarding location, waiting time period, and whether the user is at high risk of developing severe symptoms or is at high risk of infection.

The boarding location setting device 15 sets the boarding location of the service vehicle dispatched in response to a boarding request from a user. At this time, the boarding location setting device 15 sets the boarding location so as to prevent mixing of people who are at high risk of developing severe symptoms if infected with an infectious disease with people who are likely to be infected with the infectious disease, thereby reducing the risk of people at high risk of developing severe symptoms becoming infected with the infectious disease.

Specifically, the boarding location setting device 15 accepts a boarding request from a user, extracts multiple candidate boarding locations, extracts service vehicles to be dispatched to the extracted multiple candidate boarding locations, and calculates a waiting time period during which the user will wait to board the service vehicle at the multiple candidate boarding locations. It then extracts other users who will use the multiple candidate boarding locations during the calculated waiting time period, and determines whether the user has a high risk of developing severe symptoms if infected with an infectious disease. Furthermore, if the user is a user who has a high risk of developing severe symptoms, the boarding location setting device 15 determines whether the extracted other users are likely to be infected with an infectious disease. As a result, from among the multiple candidate boarding locations, a candidate boarding location with fewer other users who are likely to be infected with an infectious disease is prioritized and set as the user's boarding location.

The boarding location setting device 15 also accepts a boarding request from a user, extracts multiple candidate boarding locations, extracts service vehicles to be dispatched to the extracted multiple candidate boarding locations, and calculates a waiting time period during which the user will wait to board the service vehicle at the multiple candidate boarding locations. It then extracts other users who will use the multiple candidate boarding locations during the calculated waiting time period, and determines whether the users are likely to be infected with an infectious disease. Furthermore, if the user is likely to be infected with an infectious disease, the boarding location setting device 15 determines whether the extracted other users are at high risk of developing severe symptoms if infected with the infectious disease. As a result, from among the multiple candidate boarding locations, a candidate boarding location with fewer other users at high risk of developing severe symptoms is prioritized and set as the user's boarding location.

In this way, the boarding location setting device 15 prioritizes boarding locations with few users at high risk of infection or few users at high risk of developing severe symptoms as the user's boarding location from among the candidate boarding locations. Therefore, the boarding location setting device 15 can prevent people at high risk of developing severe symptoms and people at high risk of infection from mixing together, thereby reducing the risk of people at high risk of developing severe symptoms becoming infected with an infectious disease.

The boarding location setting device 15 is a controller composed of general-purpose electronic circuits including a microcomputer, a microprocessor, and a CPU, and peripheral devices such as memory, and has a function of setting the boarding location of a service vehicle dispatched in response to a boarding request from a user. Each function of the boarding location setting device 15 can be implemented by one or more processing circuits. The processing circuits include programmed processing devices, such as processing devices including electrical circuits, and also include devices such as application specific integrated circuits (ASICs) and conventional circuit components arranged to perform the functions described in the embodiments.

Next, the user terminal 20 will be described. The user terminal 20 is a device that can access the server 10 via a network, and is, for example, a mobile terminal (smartphone, tablet, etc.) that a user uses on a daily basis. The user terminal 20 has installed therein applications necessary for executing the services provided by the vehicle dispatch system 1. Therefore, the user terminal 20 can transmit necessary information to the server 10, and can receive and display information transmitted from the server 10. As shown in FIG. 1, the user terminal 20 includes a communication unit 21, a controller 23, and an input unit 25.

The communication unit 21 has a function of transmitting and receiving information to and from the server 10 via a network, storing the received information in a memory or the like (not shown), and transmitting predetermined information such as a boarding request. For example, the communication unit 21 may be a device equipped with a mobile communication function such as 5G.

The controller 23 accepts a boarding request from a user based on the user's operation on the input unit 25. When inputting a boarding request, the user inputs a boarding location from which the user will board the service vehicle as well as a destination, etc.

The controller 23 is a general-purpose microcomputer equipped with a CPU (Central Processing Unit) and a memory. A computer program for functioning as part of the user terminal 20 is installed in the controller 23. By executing the computer program, the controller 23 controls the communication unit 21. The various information processing functions of the controller 23 may be realized by software or by dedicated hardware.

The input unit 25 is an input interface that accepts operations from a user. For example, the input unit 25 may be a device operated with multiple buttons or a touch panel.

Next, the on-board terminal 30 will be described. The on-board terminal 30 is a device that is mounted on a service vehicle and can access the server 10 via a network. Applications necessary for executing the services provided by the vehicle dispatch system 1 are installed in the on-board terminal 30. Therefore, the on-board terminal 30 can transmit necessary information to the server 10, and can receive and display information transmitted from the server 10. As shown in FIG. 1, the on-board terminal 30 includes a communication unit 31 and a controller 33.

The communication unit 31 has a function of transmitting and receiving information to and from the server 10 via a network, storing the received information in a memory or the like (not shown), and transmitting predetermined information such as the position information of the service vehicle. For example, the communication unit 31 may be a device equipped with a mobile communication function such as 5G.

The controller 33 displays the driving route transmitted from the server 10 on a display and instructs the driver of the service vehicle on the driving route. The controller 33 also periodically transmits the position information of the service vehicle to the server 10.

The controller 33 is a general-purpose microcomputer equipped with a CPU (Central Processing Unit), memory, and input/output units. A computer program for functioning as part of the in-vehicle terminal 30 is installed in the controller 33. By executing the computer program, the controller 33 controls the communication unit 31. The various information processing functions of the controller 33 may be realized by software or by dedicated hardware.

[How to set boarding location]
Next, a description will be given of a boarding location setting method by the boarding location setting device 15 according to this embodiment. Figures 2A and 2B are flowcharts showing the processing procedure of boarding location setting processing by the boarding location setting device 15 according to this embodiment.

As shown in FIG. 2A, in step S101, the boarding location setting device 15 accepts a boarding request transmitted from the user terminal 20 via the communication unit 11. The boarding request includes the user's desired boarding location, boarding time, destination, and other boarding conditions, as well as the user's location information.

In step S103, the boarding location setting device 15 extracts multiple candidate boarding locations in response to the boarding request received in step S101. For example, as shown in FIG. 3, when the user transfers to a service vehicle at a train station and travels to the destination, boarding locations A to C are extracted as candidate boarding locations.

In step S105, the boarding location setting device 15 searches for a travel route from each of the multiple boarding location candidates extracted in step S103 to the destination. For example, as shown in FIG. 3, if boarding locations A to C are extracted as boarding location candidates, route A via boarding location A, route B via boarding location B, and route C via boarding location C are searched for.

In step S107, the boarding location setting device 15 extracts a service vehicle that can be dispatched for each of the boarding candidate locations extracted in step S103. The boarding location setting device 15 extracts a service vehicle that can arrive at each boarding candidate location first.

In step S109, the boarding location setting device 15 receives location information from each service vehicle extracted in step S107.

In step S111, the boarding location setting device 15 calculates the user's arrival time for each of the candidate boarding locations extracted in step S103. The boarding location setting device 15 calculates the time at which the user can arrive at each candidate boarding location from the user's location information. If the user is traveling on foot, the arrival time can be calculated from the walking speed, and if the user is traveling by train as shown in FIG. 3, the arrival time can be calculated from the train arrival time.

In step S113, the boarding location setting device 15 calculates the arrival time of the service vehicle extracted in step S107 for each of the candidate boarding locations extracted in step S103.

In step S115, the boarding location setting device 15 calculates a waiting time period during which the user will wait to board the service vehicle for each of the candidate boarding locations extracted in step S103. The boarding location setting device 15 calculates a waiting time period during which the user will wait to board at each candidate boarding location based on the arrival time of the user calculated in step S111 and the arrival time of the service vehicle calculated in step S113. Specifically, the waiting time period is the time period from the arrival time of the user to the arrival time of the service vehicle, and is calculated as the time period from 12:10 to 12:20, for example.

In step S117, the boarding location setting device 15 extracts other users who will use each candidate boarding location during the waiting time period calculated in step S115. From among other users who have made boarding requests via the dispatch system 1, the boarding location setting device 15 extracts other users who will use each candidate boarding location extracted in step S103 during the same time period as the waiting time period calculated in step S115. For example, as shown in FIG. 3, if boarding locations A to C have been extracted as candidate boarding locations, other users who will use boarding locations A to C during the calculated waiting time period are extracted.

In step S119, the boarding location setting device 15 calculates the number of people waiting at each candidate boarding location, and extracts candidate boarding locations where the number of people waiting is less than a threshold value. The boarding location setting device 15 counts the number of other users extracted in step S117, calculates the number of people waiting for each candidate boarding location, and extracts candidate boarding locations where the calculated number of people waiting is less than a preset threshold value.

The threshold number of people waiting is set according to the infection prevention guidelines created by government agencies. The guidelines recommend maintaining a 2m distance between people, so as shown in Figure 4, the distance between boarding point X of the service vehicle and boarding point Y of another bus or taxi is divided into 2m intervals and the threshold number of people waiting is set. In addition, when people line up in two rows, the threshold number of people waiting is set so that a space of 2m x 2m is secured, as shown in Figure 5.

As shown in FIG. 2B, in step S121, the boarding location setting device 15 determines whether or not the user is highly likely to be infected with an infectious disease. If the user stays for a predetermined period of time or more in a facility with a high risk of infection during the incubation period of the infectious disease, the boarding location setting device 15 determines that the user is highly likely to be infected with an infectious disease. Specifically, the boarding location setting device 15 determines whether or not the user is highly likely to be infected with an infectious disease according to the flowchart in FIG. 6.

As shown in Fig. 6, in step S201, the boarding location setting device 15 judges whether or not the user has a stay history that satisfies the judgment condition during the incubation period of the infectious disease. The specific judgment condition is that the user has stayed in a specific facility that corresponds to a) or b) of (1) below and satisfies (2) during the incubation period of the infectious disease, for example, the past 1 to 12.5 days. The stay history may be obtained from the location information of the user terminal 20.
(1) Characteristics of specific facilities a) Facilities that meet the conditions of the 3 Cs Closed: indoor space that does not comply with the standards for adjusting the air environment in the Building Management Act Crowded: density of 0.5 people/m2 ^{or more} when using the facility at maximum capacity in standard operating mode Close contact: conversations and vocalizations take place within a distance of 1 meter b) An infected person occurs on the day of use by the user, or an infected person has occurred in the past, and measures to avoid infection have not been made public (2) Duration and frequency of stay 15 minutes or more per visit, and stays at least once

If the result of this determination is that there is a stay history that satisfies the determination condition, the process proceeds to step S203, where the boarding location setting device 15 determines that the user is a user who is highly likely to be infected with an infectious disease. On the other hand, if there is no stay history that satisfies the determination condition, the process proceeds to step S205.

In step S205, the boarding location setting device 15 determines whether there is any missing data in the user's movement history during the incubation period. If there is no missing data in the movement history, the process proceeds to step S207, where the boarding location setting device 15 determines that the user is not a user who is likely to be infected with an infectious disease. On the other hand, if there is a missing data in the movement history, the process proceeds to step S209. The movement history may be obtained from the location information of the user terminal 20. In addition, in order to distinguish between a case where there is no movement history and a case where there is a missing data, the date and time when the movement history was obtained is recorded.

In step S209, the boarding location setting device 15 determines whether or not it is possible to acquire the user's movement history information from before the incubation period. If it is possible to acquire the movement history information, the process proceeds to step S211. If it is not possible to acquire the movement history information, the process proceeds to step S213.

In step S211, the boarding location setting device 15 estimates from the stay history before the incubation period and determines whether or not a stay that satisfies the judgment condition is expected to occur during the incubation period. Specifically, the boarding location setting device 15 calculates the average stay frequency (times/day) at the specific facility during the period before the incubation period from the movement history information before the incubation period, and estimates the stay occurrence date by assuming that a stay occurred at the calculated average stay frequency since the last observed stay record. Then, if any of the estimated stay occurrence dates fall within the incubation period, it is determined that a stay that satisfies the judgment condition is expected to occur, and if none fall within the incubation period, it is determined that a stay that satisfies the judgment condition is not expected to occur.

If it is determined that a stay that satisfies the judgment condition is expected to occur, the process proceeds to step S203, where the boarding location setting device 15 determines that the user is a user who is highly likely to be infected with an infectious disease. On the other hand, if it is determined that a stay that satisfies the judgment condition is not expected to occur, the process proceeds to step S207, where the boarding location setting device 15 determines that the user is not a user who is highly likely to be infected with an infectious disease.

Next, a case where movement history information cannot be acquired in step S209 will be described. In this case, the process proceeds to step S213, where the boarding location setting device 15 determines whether or not the user's preference information has been acquired through a questionnaire at the time of user registration. If the user's preference information has been acquired, the process proceeds to step S215, and if the user's preference information has not been acquired, the process proceeds to step S203. In step S203, the boarding location setting device 15 determines that the user is highly likely to be infected with an infectious disease.

In step S215, the boarding location setting device 15 estimates from the stay history of a group of users with similar tastes whether or not a stay that satisfies the judgment condition is expected to occur during the incubation period. Specifically, the boarding location setting device 15 conducts a questionnaire to confirm preferences regarding facility visits at the time of user registration, and calculates a representative value (median, average, etc.) of the average stay frequency at a specific facility for a group of users with similar tastes. Then, the boarding location setting device 15 uses the representative value (median, average, etc.) to estimate whether or not a stay at a specific facility by a user will occur during the incubation period.

As a result, if the user's stay at the specific facility occurs during the incubation period, the boarding location setting device 15 determines that a stay that satisfies the judgment condition is expected to occur, proceeds to step S203, and determines that the user is a user who is likely to be infected with an infectious disease. On the other hand, if the user's stay at the specific facility does not occur during the incubation period, it determines that a stay that satisfies the judgment condition is not expected to occur, proceeds to step S207, and the boarding location setting device 15 determines that the user is not a user who is likely to be infected with an infectious disease.

In this way, once it has been determined whether or not the user is highly likely to be infected with an infectious disease, the process returns to step S121 in the flowchart of FIG. 2. If it is determined in step S121 that the user is highly likely to be infected with an infectious disease, the process proceeds to step S123, and if it is determined that the user is not highly likely to be infected with an infectious disease, the process proceeds to step S125.

In step S123, the boarding location setting device 15 prioritizes a boarding location with fewer other users at high risk of developing severe symptoms among the multiple boarding locations as the boarding location for the user. Specifically, if the user is highly likely to be infected with an infectious disease, the boarding location setting device 15 determines whether or not the other users at the boarding location extracted in step S119 are at high risk of developing severe symptoms if they are infected with an infectious disease. Since the other users have determined whether or not they are at high risk of developing severe symptoms when making a boarding request in the vehicle dispatch system 1, by obtaining the determination result, it is possible to determine whether or not the other users are at high risk of developing severe symptoms. Therefore, the boarding location setting device 15 counts the number of other users at high risk of developing severe symptoms for each boarding location, and prioritizes a boarding location with fewer other users at high risk of developing severe symptoms among the boarding location. For example, the boarding location setting device 15 sets the boarding location for the user to the boarding location with the fewest other users at high risk of developing severe symptoms.

In step S125, the boarding location setting device 15 determines whether the user has a high risk of developing severe symptoms if infected with an infectious disease. Based on the registration information at the time of user registration, the boarding location setting device 15 determines that the user is at high risk of developing severe symptoms if the user has the attributes of an elderly person aged 65 or older or an infant aged 5 or younger. The boarding location setting device 15 also determines that the user is at high risk of developing severe symptoms if the user has the attributes of a person with a chronic or underlying illness, a severely obese person with a BMI (Body Mass Index) of 30 or more, or a pregnant woman. As a result, if the user is determined to be at high risk of developing severe symptoms, the process proceeds to step S127, and if the user is determined not to be at high risk of developing severe symptoms, the process proceeds to step S129.

In step S127, the boarding location setting device 15 prioritizes a boarding location with fewer other users who are likely to be infected with an infectious disease from among the multiple boarding location candidates, and sets it as the user's boarding location. Specifically, if the user is a user with a high risk of becoming seriously ill, the boarding location setting device 15 determines whether or not the other users at the boarding location extracted in step S119 are likely to be infected with an infectious disease. Since the other users have determined whether or not they are likely to be infected with an infectious disease when making a boarding request in the vehicle dispatch system 1, by obtaining the determination result, it is possible to determine whether or not the other users are likely to be infected with an infectious disease. Therefore, the boarding location setting device 15 counts the number of other users who are likely to be infected with an infectious disease for each boarding location candidate, and prioritizes a boarding location with fewer other users who are likely to be infected with an infectious disease from among the boarding location candidates, and sets it as the user's boarding location. For example, the boarding location setting device 15 sets the boarding location with the fewest other users who are likely to be infected with an infectious disease to the user's boarding location.

In step S129, the boarding location setting device 15 calculates a route from the boarding location set in step S123 or S127 to the destination, and transmits the calculated route and the set boarding location to the user terminal 20 to present to the user. For example, the route to the destination that takes the shortest time is presented. Note that if the user is not at high risk of infection (if No in step S121) and is not at high risk of developing severe symptoms (if No in step S125), the boarding location and route that takes the shortest time to reach the destination may be presented.

In step S131, if the user approves the boarding location and the route to the destination presented in step S129, the boarding location setting device 15 confirms the presented boarding location and the route to the destination. In addition, since a service vehicle that can be dispatched to the boarding location was extracted in step S107, the service vehicle is confirmed at the same time as the boarding location is confirmed.

In step S133, the boarding location setting device 15 records the boarding location, the route to the destination, and the service vehicle confirmed in step S131 in the database 13. At the same time, the boarding location setting device 15 also records in the database 13 the waiting time period, whether the user is at high risk of developing severe symptoms, and whether there is a high possibility that the user is infected with an infectious disease. In this way, when the boarding location and the route to the destination are confirmed and recorded in the database 13, the boarding location setting process according to this embodiment is terminated.

[Effects of the embodiment]
As described above in detail, the boarding location setting device 15 according to this embodiment extracts other users who use multiple boarding candidate locations during the waiting time when the user waits to board the service vehicle. Then, if the user is a user with a high risk of developing severe symptoms, it is determined whether the extracted other users are likely to be infected with an infectious disease. As a result, the boarding location setting device 15 prioritizes a boarding candidate location with fewer other users with a high risk of being infected with an infectious disease from among the multiple boarding candidate locations and sets it as the boarding location for the user. This makes it possible to prevent people with a high risk of developing severe symptoms and people with a high risk of infection from being mixed at the boarding location during the waiting time, so that it is possible to set a boarding location with a low risk of contact between people with a high risk of developing severe symptoms and people with a high risk of infection. Therefore, it is possible to reduce the risk of people with a high risk of developing severe symptoms being infected with an infectious disease.

In addition, the boarding location setting device 15 according to this embodiment extracts other users who use multiple candidate boarding locations during the waiting time when the user is waiting to board the service vehicle. If the user is highly likely to be infected with an infectious disease, the boarding location setting device 15 determines whether the extracted other users have a high risk of becoming seriously ill if infected with the infectious disease. As a result, the boarding location setting device 15 prioritizes a candidate boarding location with fewer other users at high risk of becoming seriously ill from among the multiple candidate boarding locations and sets it as the user's boarding location. This makes it possible to prevent people at high risk of becoming seriously ill and people at high risk of infection from being mixed at a boarding location during the waiting time, so it is possible to set a boarding location with a low risk of contact between people at high risk of becoming seriously ill and people at high risk of infection. Therefore, it is possible to reduce the risk of people at high risk of becoming seriously ill becoming infected with an infectious disease.

Furthermore, in the boarding location setting device 15 according to this embodiment, if the user or another user stays in a facility with a high risk of infection for a predetermined period of time or more during the incubation period of an infectious disease, the user or another user is determined to be a user with a high probability of infection with the infectious disease. This makes it possible to reliably detect users with a high probability of infection with the infectious disease, thereby preventing people with a high risk of developing severe symptoms and people with a high risk of infection from mixing together at the boarding location during waiting times, thereby reducing the risk of people with a high risk of developing severe symptoms becoming infected with the infectious disease.

In addition, in the boarding location setting device 15 according to this embodiment, if the user or another user is elderly, an infant, a person with a chronic or underlying illness, a severely obese person, or a pregnant woman, the user or another user is determined to be at high risk of developing severe symptoms if infected with an infectious disease. This makes it possible to reliably detect users at high risk of developing severe symptoms if infected with an infectious disease, thereby preventing people at high risk of developing severe symptoms and people at high risk of infection from being mixed together at the boarding location during waiting times, thereby reducing the risk of people at high risk of developing severe symptoms contracting an infectious disease.

The above-described embodiment is one example of the present invention. Therefore, the present invention is not limited to the above-described embodiment, and various modifications can be made to the design, etc., even if the embodiment is different from the above-described embodiment, as long as the modifications do not deviate from the technical concept of the present invention.

A boarding location setting method characterized in that, from among the multiple candidate boarding locations, a candidate boarding location with fewer other users who are determined to have a high possibility of infection with an infectious disease is prioritized and set as the user's boarding location. A boarding location setting method for setting a boarding location of a service vehicle dispatched in response to a boarding request from a user, comprising:
Accepting a boarding request from the user and extracting a plurality of candidate boarding locations;
Calculating a waiting time period during which the user will wait to board the service vehicle at the multiple boarding candidate locations;
Extracting other users who will use the plurality of boarding candidate locations during the calculated waiting time period;
determining whether the user is likely to be infected with an infectious disease;
If the user stays in a facility with a high risk of infection for a predetermined period of time or more during the incubation period of the infectious disease, the user is determined to be a user who is highly likely to be infected with the infectious disease;
If it is determined that the user is highly likely to be infected with an infectious disease, it is determined whether the extracted other users have a high risk of developing a severe illness if infected with the infectious disease;
A boarding location setting method characterized in that, from among the multiple candidate boarding locations, a candidate boarding location with fewer other users at high risk of developing severe symptoms is prioritized and set as the user's boarding location. The boarding location setting method described in claim 1 or 2, characterized in that if the user or the other user is an elderly person, an infant, a person with a chronic or underlying illness, a severely obese person, or a pregnant woman, the user or the other user is determined to be at high risk of developing severe symptoms if infected with an infectious disease.
