Further, the adjustment unit 28 decreases the amount of change in the boundary position as the number of times the expanded area vehicle allocation mode is performed during the predetermined period is smaller.

[Dispatch method]
Next, a vehicle allocation method according to this embodiment will be explained. In the vehicle dispatch method according to the present embodiment, the vehicle 10 is dispatched to the user by using the vehicle dispatch system SYS described above.

FIG. 4 is a diagram showing an example of vehicle dispatch by the vehicle dispatch system SYS. As shown in FIG. 4, for example, when a vehicle allocation request is made to the vehicle dispatch center 30 from the telephone 41 in the divided area AR1 (the vehicle dispatch position is the position of the telephone 41), the operator of the vehicle dispatch center 30 uses the vehicle dispatch terminal 31 to dispatch a vehicle. A vehicle allocation request is sent to the server 20. When the vehicle allocation server 20 receives a vehicle allocation request from the vehicle allocation terminal 31, the vehicle search unit 26 searches for an empty vehicle 10 assigned to the divided area AR1 where the vehicle allocation position exists from among the plurality of vehicles 10. . For example, the vehicle search unit 26 searches for the closest vehicle 10a from the vehicle allocation position. The vehicle allocation instruction unit 27 allocates the vehicle 10a to the vehicle allocation position based on the search result of the vehicle search unit 26. In this example, the vehicle allocation instruction unit 27 performs the first vehicle allocation mode in response to the vehicle allocation request from the vehicle allocation terminal 31, in which the vehicle 10a is allocated to the divided area AR1 where the vehicle allocation position exists.

Further, as shown in FIG. 4, for example, when a vehicle allocation request is made from the telephone 42 in the divided area AR2 to the vehicle dispatch center 30 (the vehicle dispatch position is assumed to be the position of the telephone 42), the operator of the vehicle dispatch center 30 A vehicle dispatch request is sent to the vehicle dispatch server 20. When the vehicle allocation server 20 receives a vehicle allocation request from the vehicle allocation terminal 31, the vehicle search unit 26 searches for an empty vehicle 10 assigned to the divided area AR2 where the vehicle allocation position exists from among the plurality of vehicles 10. . For example, the vehicle search unit 26 searches for the closest vehicle 10d from the vehicle allocation position. The vehicle allocation instruction unit 27 allocates the vehicle 10d to the vehicle allocation position based on the search result of the vehicle search unit 26. In this example, the vehicle allocation instruction unit 27 performs the first vehicle allocation mode in response to the vehicle allocation request from the vehicle allocation terminal 31, in which the vehicle 10d is allocated to the divided area AR2 where the vehicle allocation position exists.

In this way, when the vehicle allocation instruction unit 27 performs the first vehicle allocation mode, the vehicles 10 in each divided area do not lose the opportunity to be allocated due to the vehicles 10 in other divided areas, so the adjustment unit 28 Prevent the area boundary position from moving.

Further, as shown in FIG. 4, for example, when there is a vehicle allocation request from the mobile terminal 51 in the divided area AR1 to the vehicle allocation server 20 (the vehicle allocation position is the position of the mobile terminal 51), the vehicle search unit 26 Among the vehicles 10, an empty vehicle 10 existing at a position closest to the vehicle allocation position is searched. For example, the vehicle search unit 26 searches for a vehicle 10b existing in the same divided area AR1 as the vehicle allocation position. The vehicle allocation instruction unit 27 allocates the vehicle 10b to the vehicle allocation position based on the search result of the vehicle search unit 26. In this example, the vehicle allocation instruction unit 27 performs the second vehicle allocation mode in response to the vehicle allocation request from the mobile terminal 51, in which the vehicle 10b closest to the vehicle allocation position is allocated.

In this way, when the vehicle allocation instruction unit 27 performs the second vehicle allocation mode, if the vehicle allocation position and the divided area in which the vehicle allocation position exists are the same, the vehicles 10 in each divided area are different from the vehicles 10 in other divided areas. Therefore, the boundary position of the divided area should not be moved so as not to lose the opportunity to allocate a vehicle.

FIG. 5 is a diagram showing another example of vehicle dispatch by the vehicle dispatch system SYS. As shown in FIG. 5, for example, when a vehicle allocation request is made to the vehicle allocation server 20 from the mobile terminal 52 in the divided area AR1 (the vehicle allocation position is the position of the mobile terminal 52), the vehicle search unit 26 searches for a plurality of vehicles 10. An empty vehicle 10 existing at a position closest to the vehicle allocation position is searched from among the vehicles 10. For example, the vehicle search unit 26 searches for a vehicle 10d existing in a divided area AR2 different from the vehicle allocation position. The vehicle allocation instruction unit 27 allocates the vehicle 10d to the vehicle allocation position based on the search result of the vehicle search unit 26. In this example, the vehicle allocation instruction unit 27 performs the second vehicle allocation mode in response to the vehicle allocation request from the mobile terminal 52, in which the vehicle 10d closest to the vehicle allocation position is allocated.

In this way, when the vehicle 10 assigned to the divided area AR2 different from the divided area AR1 where the vehicle allocation position exists in the second vehicle allocation mode is allocated to the vehicle allocation position, that is, when the cross-area vehicle allocation mode is performed, Vehicles 10 (vehicles 10d) in the second divided area will gain profits due to the vehicle allocation request from the mobile terminal 50 (portable terminal 52), but vehicles 10 in the first divided area will lose the opportunity to allocate vehicles.

Therefore, the adjustment unit 28 changes the boundary positions of the divided areas AR1 and AR2 so that the divided area AR1 is relatively enlarged and the divided area AR2 is relatively reduced. . The adjustment unit 28 changes the boundary position based on the boundary position information and movement direction information from the divided area information management unit 23. As a result of this change, in the divided area AR1, the range in which a vehicle dispatch request from the telephone 40 can be accepted is expanded, and in the divided area AR2, the range in which a vehicle dispatch request by the telephone 40 can be accepted is narrowed.

FIG. 6 is a diagram illustrating an example of changing the boundary position of divided areas. As shown in FIG. 6, in this embodiment, divided area AR1 and divided area AR2 are adjacent to each other. In such a case, the adjustment unit 28 changes, for example, the position of the boundary line shared between the divided area AR1 and the divided area AR2. This makes it possible to efficiently realize a situation in which the divided area AR1 is relatively enlarged and the divided area AR2 is relatively reduced. In addition, in FIG. 6, the boundary position between the initially set divided area AR1 and divided area AR2 is shown by a broken line. In the example shown in FIG. 6, the adjustment unit 28 moves the position of the boundary line L1 toward the divided area AR2 side, and shortens the lengths of the boundary line L2 and the boundary line L3 according to the movement of the boundary line L1. Adjusting the border position. Note that the adjustment unit 28 is not limited to this mode, and may adjust the boundary position in other modes. For example, a plurality of boundary position candidates may be set in advance and stored in the divided area information management unit 23 by moving each of the initially set boundary positions to the divided area AR1 and divided area AR2 side in stages. good. In this case, when changing the boundary position, the adjustment unit 28 can set the boundary position by selecting one boundary position candidate from among the boundary position candidates stored in the divided area information management unit 23. can.

An example of the vehicle allocation method according to this embodiment will be described with reference to FIG. 7. FIG. 7 is a flowchart illustrating an example of the vehicle allocation method according to the present embodiment. As shown in FIG. 7, the vehicle dispatch server 20 receives a vehicle dispatch request from the vehicle dispatch center 30 or the mobile terminal 50 (step S101). If the destination of the vehicle allocation request is the vehicle allocation center 30 (No in step S102), the vehicle search unit 26 searches for an empty vehicle 10 assigned to the divided area where the vehicle allocation position exists. Further, the vehicle allocation instruction unit 27 allocates the vehicle 10 to the vehicle allocation position based on the search result of the vehicle search unit 26. That is, a first vehicle allocation mode is performed in which vehicles 10 assigned to the divided area where the vehicle allocation position exists are allocated to the vehicle allocation position (step S103). After that, the process ends.

On the other hand, if the recipient of the vehicle allocation request is the mobile terminal 50 in step S102 (Yes in step S102), the vehicle search unit 26 searches for an empty vehicle 10 that is located closest to the vehicle allocation position. Further, the vehicle allocation instruction unit 27 allocates the vehicle 10 to the vehicle allocation position based on the search result of the vehicle search unit 26. In other words, a second vehicle allocation mode is performed in which an empty vehicle 10 located closest to the vehicle allocation position is allocated to the vehicle allocation position (step S104).

When the second vehicle allocation mode is performed, the adjustment unit 28 determines whether the divided area where the vehicle allocation position exists is different from the divided area to which the allocated vehicle 10 belongs (step S105). If the adjustment unit 28 determines that the two divided areas are different (Yes in step S105), the divided area where the vehicle allocation position exists is expanded between the two divided areas, and the divided area to which the allocated vehicle 10 belongs is expanded. The boundary area between both divided areas is moved so that the area is reduced (step S106). After that, the process ends. Further, if it is determined in step S105 that the two divided areas are not different (No in step S105), the process ends.

FIG. 8 is a diagram showing another example of vehicle dispatch by the vehicle dispatch system SYS. In the example shown in FIG. 8, the boundary position between divided area AR1 and divided area AR2 has changed from the initially set position. Specifically, the divided area AR1 is relatively enlarged and the divided area AR2 is relatively reduced with respect to the initial setting. When the boundary position between the divided area AR1 and the divided area AR2 changes in this way, the vehicle 10 assigned to the divided area AR2, which is different from the divided area AR1 where the vehicle allocation position exists in the second vehicle allocation mode as described above, The boundary position of the divided area may be changed in a manner different from the above, such as when the boundary position is automatically changed depending on the time of day, season, etc. included.

In such a state, for example, if a vehicle allocation request is made to the vehicle dispatch center 30 from the telephone 43 in the divided area AR1 (the vehicle dispatch position is assumed to be the position of the telephone 43), the operator of the vehicle dispatch center 30 requests the vehicle dispatch server 20 from the vehicle dispatch terminal 31. Send a ride request to. When the vehicle allocation server 20 receives a vehicle allocation request from the vehicle allocation terminal 31, the vehicle search unit 26 searches for an empty vehicle 10 assigned to the divided area AR1 where the vehicle allocation position exists from among the plurality of vehicles 10. . For example, the vehicle search unit 26 searches for the vehicle 10b closest to the vehicle allocation position. The vehicle allocation instruction unit 27 allocates the vehicle 10b to the vehicle allocation position based on the search result of the vehicle search unit 26. In this example, the vehicle allocation instruction unit 27 performs the first vehicle allocation mode in response to the vehicle allocation request from the vehicle allocation terminal 31, in which the vehicle 10b allocated to the divided area AR1 where the vehicle allocation position exists.

Note that the telephone 43 exists in an area expanded by changing the boundary position of the divided area AR1. The adjustment unit 28 certifies the area obtained by subtracting the divided area AR1 at the time when the dispatch request was made by the telephone 43 from the divided area AR1 that was set most recently before the change, as the area that has been expanded due to the change in the boundary position. Can be done.

In this way, after the boundary position is changed so that the divided area AR1 is relatively expanded and the divided area AR2 is relatively reduced, the vehicle is allocated to the vehicle allocation position within the expanded area of the divided area AR1. When a request is generated and the first vehicle allocation mode in response to the vehicle allocation request, that is, the expanded area vehicle allocation mode, is performed, the change in the boundary position results in the vehicle 10 on the divided area AR1 side having an opportunity to allocate a vehicle. On the other hand, in the divided area AR2, the change in the boundary position results in a loss of vehicle allocation opportunities.

Therefore, the adjustment unit 28 changes the boundary position of the divided areas between divided area AR1 and divided area AR2 so that divided area AR1 is relatively reduced and divided area AR2 is relatively expanded. . The adjustment unit 28 changes the boundary position based on the boundary position information and movement direction information from the divided area information management unit 23.

FIG. 9 is a diagram illustrating an example of changing the boundary position of divided areas. As shown in FIG. 9, in this embodiment, divided area AR1 and divided area AR2 are adjacent to each other. In such a case, the adjustment unit 28 changes, for example, the position of the boundary line shared by the divided area AR1 and the divided area AR2, as in the case shown in FIG. This makes it possible to efficiently realize a situation in which the divided area AR1 is relatively reduced and the divided area AR2 is relatively expanded. In addition, in FIG. 9, the boundary position between the divided area AR1 and the divided area AR2 that was set immediately before is shown by a broken line. In the example shown in FIG. 9, the adjustment unit 28 moves the position of the boundary line L1 toward the divided area AR1 side, and increases the lengths of the boundary line L2 and the boundary line L3 according to the movement of the boundary line L1. Adjusting the border position. Note that the adjustment unit 28 is not limited to this mode, and may adjust the boundary position in other modes.

Another example of the vehicle allocation method according to this embodiment will be described with reference to FIG. 10. FIG. 10 is a flowchart showing another example of the vehicle allocation method according to this embodiment. As shown in FIG. 10, the vehicle allocation server 20 determines whether the boundary position of the divided area has moved with respect to the initially set position (step S201). If it is determined that the object is not moving (No in step S201), the process ends. If it is determined that the vehicle is moving (Yes in step S201), the vehicle dispatch server 20 receives a vehicle dispatch request from the vehicle dispatch center 30 or the mobile terminal 50 (step S202). If the recipient of the vehicle allocation request is the mobile terminal 50 (No in step S203), the vehicle search unit 26 searches for an empty vehicle 10 that is located closest to the vehicle allocation position. Further, the vehicle allocation instruction unit 27 allocates the vehicle 10 to the vehicle allocation position based on the search result of the vehicle search unit 26. In other words, a second vehicle allocation mode is performed in which the empty vehicle 10 that is closest to the vehicle allocation position is allocated to the vehicle allocation position (step S204). After that, the process ends.

On the other hand, in step S203, if the receiving destination of the vehicle allocation request is the vehicle allocation center 30 (Yes in step S203), the vehicle search unit 26 searches for an empty vehicle 10 assigned to the divided area where the vehicle allocation position exists. . Further, the vehicle allocation instruction unit 27 allocates the vehicle 10 to the vehicle allocation position based on the search result of the vehicle search unit 26. That is, a first vehicle allocation mode is performed in which the vehicle 10 assigned to the divided area where the vehicle allocation position exists is allocated to the vehicle allocation position (step S205).

When the first vehicle allocation mode is performed, the adjustment unit 28 determines whether the vehicle allocation position is within an area of the divided area that has been expanded by changing the boundary position (step S206). If the adjustment unit 28 determines that the area is within the expanded area (Yes in step S206), between the two divided areas, the divided area where the vehicle allocation position exists is reduced, and the divided area where the vehicle allocation position does not exist is expanded. The boundary area between the two divided areas is moved so that the area is moved (step S207). After that, the process ends. If it is determined in step S206 that the area is not within the enlarged area (No in step S206), the process ends.

As described above, in the vehicle dispatch system SYS, the vehicle dispatch method, and the vehicle dispatch program according to the present embodiment, the business area AR is divided into a plurality of divided areas AR1 to AR3, and a predetermined number of vehicles 10 are assigned to each divided area. , a first vehicle allocation mode in which, when a request for vehicle allocation to a vehicle allocation position in a first divided area among a plurality of divided areas occurs, an empty vehicle 10 assigned to the first divided area is allocated to the vehicle allocation position; The vehicle allocation instruction unit 27 performs a second vehicle allocation mode in which an empty vehicle 10 existing at a position closest to the vehicle allocation position is allocated to the vehicle allocation position, and is allocated to a second divided area different from the first divided area in the second vehicle allocation mode. When the vehicles 10 assigned to the vehicle allocation position are allocated to the vehicle allocation position, the adjustment unit 28 determines the number of vehicles 10 per unit area allocated to the first divided area between the first divided area and the second divided area. is relatively decreased, and the number of vehicles 10 assigned to the second divided area per unit area is relatively increased.

Specifically, the boundary positions of the plurality of divided areas can be changed, and between the first divided area and the second divided area, the first divided area is relatively enlarged, and the second divided area is relatively expanded. The boundary position is changed by the adjustment unit 28 so that the image is reduced in size.

According to the above configuration, it is possible to widen the range in which a vehicle allocation request via the telephone 40 can be accepted for the first divided area, and narrow the range in which a vehicle allocation request via the telephone 40 can be accepted in the second divided area. Therefore, the opportunities for vehicle allocation in the first divided area can be relatively increased, and the opportunities for vehicle allocation in the second divided area can be relatively decreased. Therefore, it is possible to adjust the profits between the second divided area side, which gained a profit from the cross-area vehicle allocation mode, and the first divided area side, which lost the opportunity to dispatch vehicles. Thereby, it is possible to prevent the fairness of the number of vehicles allocated between divided areas from being impaired.

Furthermore, in the vehicle dispatch system SYS, vehicle dispatch method, and vehicle dispatch program according to the present embodiment, in the business area AR that is divided into a plurality of divided areas AR1 to AR3 and a predetermined number of vehicles 10 are assigned to each divided area, a plurality of When a request for dispatching a vehicle to a vehicle dispatching position in a first divided area among the divided areas occurs, a first dispatching mode in which an empty vehicle 10 assigned to the first divided area is dispatched to the dispatching position, or The vehicle dispatch instruction unit 27 performs a second dispatch mode in which the empty vehicle 10 existing at the closest position is dispatched to the dispatch position, and the first divided area among the plurality of divided areas and the second divided area different from the first divided area are After the boundary position is changed so that the first divided area is relatively expanded and the second divided area is relatively reduced between the divided areas, the area within the expanded area of the first divided area When a vehicle allocation request to a vehicle allocation position occurs and the first vehicle allocation mode is performed in response to the vehicle allocation request, the first divided area is relatively reduced between the first divided area and the second divided area. , the boundary position is changed by the adjustment unit 28 so that the second divided area is relatively enlarged.

According to the above configuration, it is possible to widen the range in which vehicle dispatch requests from the telephone 40 can be accepted for the second divided area, and it is possible to narrow the range in which vehicle dispatch requests by the telephone 40 can be accepted for the first divided area. Therefore, the opportunities for vehicle allocation in the second divided area can be relatively increased, and the opportunities for vehicle allocation in the first divided area can be relatively reduced. Therefore, it is possible to adjust the profits between the first divided area side, which has gained a profit by changing the boundary position, and the second divided area side, which has lost the opportunity to allocate vehicles. Thereby, it is possible to prevent the fairness of the number of vehicles allocated between divided areas from being impaired.

The vehicle dispatch system SYS according to the present embodiment includes a divided area information management unit 23 that stores a plurality of candidates for the changed boundary position, and the adjustment unit 28 selects one candidate from among the plurality of candidates. Set the changed boundary position. This allows the boundary position to be set smoothly.

In the vehicle dispatch system SYS according to the present embodiment, the adjustment unit 28 sets the amount of change in the boundary position according to the number of times the cross-area vehicle dispatch mode or the expanded area vehicle dispatch mode is performed in a predetermined period. As a result, the amount of change in the boundary position is set according to the number of times a vehicle allocation opportunity is obtained or a vehicle allocation opportunity is lost, so it is possible to more appropriately adjust profits between divided areas.

In the vehicle dispatch system SYS according to the present embodiment, the vehicle dispatch instruction unit 27 performs the first vehicle dispatch mode when receiving a vehicle dispatch request from the vehicle dispatch terminal 31 of the vehicle dispatch center 30, and uses a terminal different from the vehicle dispatch terminal 31 to When receiving a vehicle dispatch request from a mobile terminal 50 that can grasp the location of vehicle 10, the second vehicle dispatch mode is performed. Thereby, it is possible to adjust the profits between the second divided area side, which gained profit from the vehicle allocation request from the mobile terminal 50, and the first divided area side, which lost the opportunity to allocate a vehicle.

In the above-described embodiment, when the cross-area dispatch mode is performed, the first divided area is relatively expanded and the second divided area is relatively expanded between the first divided area and the second divided area. Although the description has been given using an example in which the boundary position of the divided area is changed so that the divided area is reduced in size, the present invention is not limited to this. For example, when the cross-area vehicle allocation mode is performed, the adjustment unit 28 relatively reduces the number of vehicles 10 assigned to the first divided area between the first divided area and the second divided area, Adjustments may be made to relatively increase the number of vehicles allocated to the second divided area.

FIG. 11 is a diagram showing another mode of adjustment by the adjustment unit 28. Note that FIG. 11 shows a cross-area vehicle allocation mode in which a vehicle 10 (for example, vehicle 10d) assigned to divided area AR2 is allocated to a vehicle allocation position (for example, the position of mobile terminal 52) existing in divided area AR1. This is an example of a case where In this case, the vehicle 10d in the divided area AR2 will gain a profit due to the vehicle allocation request from the mobile terminal 52, but the vehicle 10 (vehicles 10a to 10c) in the divided area AR1 will lose the opportunity to allocate a vehicle.

Therefore, as shown in FIG. 11, the adjustment unit 28 causes some (for example, one or several vehicles) of the vehicles 10 belonging to the divided area AR1 to belong to the divided area AR2. In FIG. 11, as an example, the vehicle 10a belongs to the divided area AR2, but the present invention is not limited to this, and the vehicles 10b and 10c may belong to the divided area AR1. By changing the affiliation of vehicles 10 in this manner, the number of vehicles 10 assigned to divided area AR1 is relatively reduced, and the number of vehicles assigned to divided area AR2 is relatively increased. Thereafter, when a vehicle allocation request is received from the telephone 40 in the divided area AR2, the vehicle allocation instruction unit 27 issues a vehicle allocation instruction preferentially to the vehicle 10 (vehicle 10a) whose affiliation has been changed to the divided area AR2.

This reduces the number of vehicles 10 per unit area in divided area AR1. For this reason, it is possible to increase the expected value for each vehicle 10 belonging to the divided area AR1 to receive a vehicle assignment in response to a vehicle assignment request made by the telephone 40. On the other hand, in divided area AR2, the number of vehicles 10 per unit area increases. Therefore, it is possible to lower the expected value for each vehicle 10 belonging to the divided area AR2 to receive a vehicle assignment in response to a vehicle assignment request made by the telephone 40. Therefore, it is possible to relatively increase the number of vehicle allocation opportunities for each vehicle 10 belonging to the divided area AR1, and to relatively decrease the number of vehicle allocation opportunities for each vehicle 10 belonging to the divided area AR2.

FIG. 12 is a diagram showing another mode of adjustment by the adjustment section 28. Note that FIG. 12 shows that after the affiliation of the vehicle 10 is changed in FIG. This is an example of a case where a cross-area vehicle dispatch mode is performed in which a vehicle is dispatched to a location of . In this case, the vehicle 10 in the divided area AR1 will gain a profit due to the vehicle allocation request from the mobile terminal 50, but the vehicle 10 in the divided area AR2 will lose the opportunity to allocate a vehicle.

Therefore, as shown in FIG. 12, the adjustment unit 28 causes some (for example, one or several vehicles) of the vehicles 10 belonging to the divided area AR2 to belong to the divided area AR1. In FIG. 12, as an example, the vehicle 10a belongs to the divided area AR1, but the present invention is not limited to this, and the vehicles 10d, 10e, and 10f may belong to the divided area AR1. By changing the affiliation of the vehicles 10 in this manner, the number of vehicles 10 assigned to the divided area AR2 is relatively reduced, and the number of vehicles assigned to the divided area AR1 is relatively increased. Thereafter, when a vehicle allocation request is received from the telephone 40 in the divided area AR1, the vehicle allocation instruction unit 27 issues a vehicle allocation instruction preferentially to the vehicle 10 (vehicle 10a) whose affiliation has been changed to the divided area AR1.

This reduces the number of vehicles 10 per unit area in divided area AR2. For this reason, it is possible to increase the expectation value for each vehicle 10 belonging to the divided area AR2 to receive a vehicle assignment in response to a vehicle assignment request made by the telephone 40. On the other hand, in divided area AR1, the number of vehicles 10 per unit area increases. Therefore, it is possible to lower the expected value for each vehicle 10 belonging to the divided area AR1 to receive a vehicle assignment in response to a vehicle assignment request made by the telephone 40. Therefore, each vehicle 10 belonging to the divided area AR2 can have a relatively large number of dispatch opportunities, and each vehicle 10 belonging to the divided area AR1 can have a relatively small number of dispatch opportunities.

The vehicle allocation method shown in FIGS. 11 and 12 will be described with reference to FIG. 13. FIG. 13 is a flowchart showing another example of the vehicle allocation method. As shown in FIG. 13, the vehicle dispatch server 20 receives a vehicle dispatch request from the vehicle dispatch center 30 or the mobile terminal 50 (step S301). If the recipient of the vehicle allocation request is the vehicle allocation center 30 (No in step S302), the first vehicle allocation mode is performed (step S303), and then the process ends.

On the other hand, if the recipient of the vehicle allocation request is the mobile terminal 50 in step S302 (Yes in step S302), the second vehicle allocation mode is performed (step S304). When the second vehicle allocation mode is performed, the adjustment unit 28 determines whether the divided area where the vehicle allocation position exists is different from the divided area to which the allocated vehicle 10 belongs (step S305). If the adjustment unit 28 determines that the two divided areas are different (Yes in step S305), the number of vehicles 10 belonging to the divided area where the vehicle allocation position exists is relatively decreased between the two divided areas, and the vehicle allocation position is changed. The number of vehicles 10 assigned to both divided areas is changed so that the number of vehicles 10 belonging to the divided area to which the assigned vehicle 10 belongs is relatively increased (step S306). After that, the process ends. Further, if it is determined in step S305 that the two divided areas are not different (No in step S305), the process ends.

In this way, when the cross-area vehicle allocation mode is performed, the adjustment unit 28 relatively reduces the number of vehicles 10 assigned to the first divided area between the first divided area and the second divided area. and relatively increase the number of vehicles assigned to the second divided area. Thereby, it is possible to adjust the profits between the second divided area side, which has gained a profit from the cross-area vehicle allocation mode, and the first divided area side, which has lost the opportunity to dispatch vehicles. Thereby, it is possible to prevent the fairness of the number of vehicles allocated between divided areas from being impaired.
