The processing unit 15 transmits the position information calculated by the GPS receiving unit 11 and the dynamic information acquired from the meter 12 to the vehicle dispatch server 20.

FIG. 3 is a functional block diagram showing an example of the vehicle allocation server 20. As shown in FIG. 3, the vehicle allocation server 20 has a database unit 21 and a vehicle allocation processing unit 22. The database unit 21 stores and manages various data related to the operation of the vehicle dispatch system SYS. The database unit 21 has a divided area information management unit 23, a vehicle information management unit 24, and a user information management unit 25.

The divided area information management unit (storage unit) 23 stores and manages information related to the divided areas AR1 to AR3. The information regarding the divided areas AR1 to AR3 includes, for example, identification information for identifying the divided areas AR1 to AR3, adjacent information about the adjacent divided areas, boundary position information indicating the boundary position between the divided areas, and enlargement or reduction of the divided area. Includes moving direction information and the like indicating the direction in which the boundary position is moved. The boundary position can be, for example, the position of the boundary line between the divided areas.

The user information management unit 25 is appropriately updated by communication with the vehicle allocation center 30 or the mobile terminal 50. The position information of the vehicle allocation position when the mobile terminal 50 requests the vehicle allocation may be, for example, the position information calculated by the mobile terminal 50.

The vehicle dispatch processing unit 22 performs various processes related to the operation of the vehicle dispatch system SYS. The vehicle allocation processing unit 22 is, for example, an arithmetic processing device composed of a CPU or the like. The vehicle dispatch processing unit 22 loads the stored program into the memory and executes the instruction included in the program. The vehicle allocation processing unit 22 includes an internal memory (not shown) and the like. In the internal memory, a program for realizing each part of the vehicle allocation processing unit 22 is stored. In this case, the vehicle allocation processing unit 22 realizes the functions of each unit by expanding and executing the program stored in the internal memory or the like. The internal memory is also used for temporary storage of data in the vehicle allocation processing unit 22.

The vehicle allocation processing unit 22 includes a vehicle search unit 26, a vehicle allocation instruction unit 27, and an adjustment unit 28. When a vehicle allocation request is received from the vehicle allocation terminal 31, the vehicle search unit 26 refers to the divided area information management unit 23, the vehicle information management unit 24, and the user information management unit 25, and searches for a vehicle 10 that can be allocated. In this case, the vehicle search unit 26 searches, for example, the empty vehicle 10 assigned to the divided area where the vehicle allocation position exists from among the plurality of vehicles 10. Further, when the mobile terminal 50 requests vehicle allocation, the vehicle search unit 26 refers to the vehicle information management unit 24 and the user information management unit 25 to search for the vehicle 10 that can be allocated. In this case, the vehicle search unit 26 searches, for example, the empty vehicle 10 existing at the position closest to the vehicle allocation position from among the plurality of vehicles 10.

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. Specifically, when the vehicle allocation instruction unit 27 receives the vehicle allocation request from the vehicle allocation terminal 31 of the vehicle allocation center 30, the vehicle allocation instruction unit 27 allocates the vehicle 10 assigned to the divided area where the vehicle allocation position exists to the vehicle allocation position. Perform the mode. Further, when the vehicle allocation instruction unit 27 receives the vehicle allocation request from the mobile terminal 50, the vehicle allocation instruction unit 27 performs a second vehicle allocation mode in which the empty vehicle 10 existing at the position closest to the vehicle allocation position is allocated to the vehicle allocation position. The vehicle allocation instruction unit 27 transmits a vehicle allocation instruction to the vehicle 10 to be allocated. Further, when the second vehicle allocation mode is performed, the vehicle allocation instruction unit 27 transmits the identification information of the vehicle 10 to be allocated to the mobile terminal 50.

In the adjusting unit 28, the vehicle 10 assigned to a division area (hereinafter referred to as the second division area) different from the division area (hereinafter referred to as the first division area) in which the vehicle allocation position exists is allocated to the vehicle allocation position. When the second vehicle allocation mode (hereinafter referred to as the area-crossing vehicle allocation mode) is performed, the vehicle 10 assigned to the first division area between the first division area and the second division area. Adjustments are made so that the number of vehicles per unit size decreases relatively and the number of vehicles 10 assigned to the second division area increases relatively. In the present embodiment, when the area-crossing vehicle allocation mode is performed, the adjustment unit 28 relatively expands the first division area between the first division area and the second division area, and the second division area becomes Change the boundary position of the divided area so that it is relatively reduced.

The adjusting unit 28 may change the boundary position each time the area-crossing vehicle allocation mode is performed. Further, the adjusting unit 28 may set the amount of change of the boundary position according to the number of times the area straddling mode is performed in the predetermined period. In this case, the adjusting unit 28 increases the amount of change in the boundary position, for example, as the number of times the area-crossing vehicle allocation mode is performed in a predetermined period. Further, the adjusting unit 28 reduces the amount of change in the boundary position as the number of times the area-crossing vehicle allocation mode is performed in a predetermined period is smaller.

Further, in the adjusting unit 28, the boundary position is set so that the first division area is relatively expanded and the second division area is relatively reduced with the second division area different from the first division area. After the change, when a vehicle allocation request is generated to a vehicle allocation position in the expanded area of the first division area and the first vehicle allocation mode (hereinafter referred to as the expanded area vehicle allocation mode) is performed in response to the vehicle allocation request, the first The boundary position of the divided area is changed so that the first divided area is relatively reduced and the second divided area is relatively expanded between the first divided area and the second divided area.

The adjusting unit 28 may change the boundary position each time the expansion area vehicle allocation mode is performed. Further, the adjusting unit 28 may set the amount of change in the boundary position according to the number of times the expansion area vehicle allocation mode is performed in a predetermined period. In this case, the adjusting unit 28 increases the amount of change in the boundary position, for example, as the number of times the expansion area vehicle allocation mode is performed in a predetermined period increases. Further, the adjusting unit 28 reduces the amount of change in the boundary position as the number of times the expanded area vehicle allocation mode is performed in a predetermined period is smaller.

[Vehicle dispatch method]
Next, the vehicle allocation method according to the present embodiment will be described. In the vehicle allocation method according to the present embodiment, the vehicle 10 is allocated to the user by using the above-mentioned vehicle allocation system SYS.

FIG. 4 is a diagram showing an example of vehicle allocation by the vehicle allocation system SYS. As shown in FIG. 4, for example, when there is a vehicle allocation request from the telephone 41 in the divided area AR1 to the vehicle allocation center 30 (the vehicle allocation position is the position of the telephone 41), the operator of the vehicle allocation center 30 dispatches the vehicle by the vehicle allocation terminal 31. A vehicle dispatch request is transmitted to the server 20. When the vehicle allocation server 20 receives the vehicle allocation request from the vehicle allocation terminal 31, the vehicle search unit 26 searches the plurality of vehicles 10 for the empty vehicle 10 assigned to the divided area AR1 in which the vehicle allocation position exists. .. For example, the vehicle search unit 26 searches for the vehicle 10a closest to 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 which the vehicle 10a assigned to the divided area AR1 where the vehicle allocation position exists is allocated in response to the vehicle allocation request from the vehicle allocation terminal 31.

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 allocation center 30 (the vehicle allocation position is the position of the telephone 42), the operator of the vehicle allocation center 30 uses the vehicle allocation terminal 31. Sends a vehicle allocation request to the vehicle allocation server 20. When the vehicle allocation server 20 receives the vehicle allocation request from the vehicle allocation terminal 31, the vehicle search unit 26 searches the plurality of vehicles 10 for the empty vehicle 10 assigned to the divided area AR2 in which the vehicle allocation position exists. .. For example, the vehicle search unit 26 searches for the vehicle 10d closest to 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 which the vehicle 10d assigned to the divided area AR2 where the vehicle allocation position exists is allocated in response to the vehicle allocation request from the vehicle allocation terminal 31.

In this way, when the vehicle allocation instruction unit 27 performs the first vehicle allocation mode, the vehicle 10 in each division area does not lose the opportunity to allocate a vehicle by the vehicle 10 in the other division area, so that the adjustment unit 28 is divided. Do not move the boundary position of the area.

Further, as shown in FIG. 4, for example, when a vehicle allocation request is made 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 may perform a plurality of vehicle allocation requests. From the vehicle 10, the empty vehicle 10 existing at the position closest to the dispatch position is searched. For example, the vehicle search unit 26 searches for a vehicle 10b existing in the same division 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 which the vehicle 10b closest to the vehicle allocation position is allocated in response to the vehicle allocation request from the mobile terminal 51.

In this way, when the vehicle allocation instruction unit 27 performs the second vehicle allocation mode, if the vehicle allocation position and the division area where the vehicle allocation position exists are the same, the vehicle 10 in each division area is the vehicle 10 in the other division area. Therefore, the opportunity to dispatch the vehicle will not be lost, so the boundary position of the divided area should not be moved.

FIG. 5 is a diagram showing another example of vehicle allocation by the vehicle allocation system SYS. As shown in FIG. 5, for example, when a vehicle allocation request is made from the mobile terminal 52 in the divided area AR1 to the vehicle allocation server 20 (the vehicle allocation position is the position of the mobile terminal 52), the vehicle search unit 26 may perform a plurality of vehicles 10. From the list, the empty vehicle 10 existing at the position closest to the vehicle allocation position is searched. 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 which the vehicle 10d closest to the vehicle allocation position is allocated in response to the vehicle allocation request from the mobile terminal 52.

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 area crossing vehicle allocation mode is performed. The vehicle 10 (vehicle 10d) in the second division area will benefit from the vehicle allocation request of the mobile terminal 50 (mobile terminal 52), but the vehicle 10 in the first division area will lose the opportunity to allocate a vehicle.

Therefore, the adjusting unit 28 changes the boundary position of the divided area between the divided area AR1 and the divided area AR2 so that the divided area AR1 is relatively expanded and the divided area AR2 is relatively reduced. .. The adjusting unit 28 changes the boundary position based on the boundary position information and the moving direction information of the divided area information management unit 23. Due to this change, the range in which the vehicle allocation request by telephone 40 can be accepted in the divided area AR1 is expanded, and the range in which the vehicle allocation request by telephone 40 can be accepted in the divided area AR2 is narrowed.

FIG. 6 is a diagram showing an example when the boundary position of the divided area is changed. As shown in FIG. 6, in the present embodiment, the divided area AR1 and the divided area AR2 are adjacent to each other. In such a case, the adjusting unit 28 changes the position of the boundary line shared by, for example, the divided area AR1 and the divided area AR2. As a result, it is possible to efficiently realize a situation in which the divided area AR1 is relatively expanded and the divided area AR2 is relatively reduced. Note that FIG. 6 shows the initially set boundary positions between the divided area AR1 and the divided area AR2 with broken lines. In the example shown in FIG. 6, the adjusting unit 28 moves the position of the boundary line L1 to the division 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. The boundary position is being adjusted. The adjusting unit 28 is not limited to this mode, and the boundary position may be adjusted in another mode. For example, a plurality of boundary position candidates that are moved stepwise to the divided area AR1 and the divided area AR2 with respect to the initially set boundary position may be set in advance and stored in the divided area information management unit 23. Good. In this case, when changing the boundary position, the adjusting unit 28 can set the boundary position by selecting one boundary position candidate from the boundary position candidates stored in the divided area information management unit 23. it can.

An example of the vehicle allocation method according to the present embodiment will be described with reference to FIG. 7. FIG. 7 is a flowchart showing an example of the vehicle allocation method according to the present embodiment. As shown in FIG. 7, the vehicle allocation server 20 receives a vehicle allocation request from the vehicle allocation center 30 or the mobile terminal 50 (step S101). When the vehicle allocation request is received at 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, the first vehicle allocation mode in which the vehicle 10 assigned to the divided area where the vehicle allocation position exists is allocated to the vehicle allocation position is performed (step S103). After that, the process ends.

On the other hand, when the receiving destination of the vehicle allocation request is the mobile terminal 50 in step S102 (Yes in step S102), the vehicle search unit 26 searches for the empty vehicle 10 existing at the position 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. That is, a second vehicle allocation mode is performed in which the empty vehicle 10 existing at the position closest to the vehicle allocation position is allocated to the vehicle allocation position (step S104).

When the second vehicle allocation mode is performed, the adjusting unit 28 determines whether or not the division area where the vehicle allocation position exists and the division area to which the dispatched vehicle 10 belongs are different (step S105). When the adjusting 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 becomes. The boundary area of both divided areas is moved so as to be reduced (step S106). After that, the process ends. If it is determined in step S105 that the two division areas are not different (No in step S105), the process ends.

FIG. 8 is a diagram showing another example of vehicle allocation by the vehicle allocation system SYS. In the example shown in FIG. 8, the boundary position between the divided area AR1 and the divided area AR2 is 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 is changed in this way, the vehicle 10 assigned to the divided area AR2 different from the divided area AR1 in which the vehicle allocation position exists in the second vehicle allocation mode as described above. Is not limited to the case where the vehicle is dispatched to the vehicle allocation position, and the boundary position of the divided area may be changed in a manner different from the above, for example, when the boundary position is automatically changed according to the time, season, etc. included.

In such a state, for example, when there is a vehicle allocation request from the telephone 43 in the divided area AR1 to the vehicle allocation center 30 (the vehicle allocation position is the position of the telephone 43), the operator of the vehicle allocation center 30 uses the vehicle allocation terminal 31 to perform the vehicle allocation server 20. Send a vehicle dispatch request to. When the vehicle allocation server 20 receives the vehicle allocation request from the vehicle allocation terminal 31, the vehicle search unit 26 searches the plurality of vehicles 10 for the empty vehicle 10 assigned to the divided area AR1 in which the vehicle allocation position exists. .. 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 which the vehicle 10b assigned to the divided area AR1 where the vehicle allocation position exists is allocated in response to the vehicle allocation request from the vehicle allocation terminal 31.

The telephone 43 exists in an area of the divided area AR1 that has been expanded by changing the boundary position. The adjusting unit 28 recognizes the area obtained by subtracting the divided area AR1 at the time when the vehicle dispatch request is made by the telephone 43 from the divided area AR1 which was set most recently before the change as the area expanded by the change of 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 dispatched to the vehicle allocation position in the expanded area of the divided area AR1. When the request is generated and the first vehicle allocation mode for the vehicle allocation request, that is, the expanded area vehicle allocation mode is performed, the vehicle 10 on the divided area AR1 side has an opportunity to allocate the vehicle due to the change of the boundary position. On the other hand, in the divided area AR2, the opportunity to dispatch a vehicle is lost due to the change in the boundary position.

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

FIG. 9 is a diagram showing an example when the boundary position of the divided area is changed. As shown in FIG. 9, in the present embodiment, the divided area AR1 and the divided area AR2 are adjacent to each other. In such a case, the adjusting unit 28 changes the position of the boundary line shared by, for example, the divided area AR1 and the divided area AR2, as in the case shown in FIG. As a result, it is possible to efficiently realize a situation in which the divided area AR1 is relatively reduced and the divided area AR2 is relatively expanded. In FIG. 9, the boundary position between the divided area AR1 and the divided area AR2 set immediately before is shown by a broken line. In the example shown in FIG. 9, the adjusting unit 28 moves the position of the boundary line L1 to the division area AR1 side, and lengthens the lengths of the boundary line L2 and the boundary line L3 according to the movement of the boundary line L1. The boundary position is being adjusted. The adjusting unit 28 is not limited to this mode, and the boundary position may be adjusted in another mode.

Another example of the vehicle allocation method according to the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart showing another example of the vehicle allocation method according to the present embodiment. As shown in FIG. 10, the vehicle allocation server 20 determines whether or not 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 has not moved (No in step S201), the process ends. When it is determined that the vehicle is moving (Yes in step S201), the vehicle allocation server 20 receives a vehicle allocation request from the vehicle allocation center 30 or the mobile terminal 50 (step S202). When the receiving destination of the vehicle allocation request is the mobile terminal 50 (No in step S203), the vehicle search unit 26 searches for the empty vehicle 10 existing at the position 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. That is, the second vehicle allocation mode in which the empty vehicle 10 existing at the position closest to the vehicle allocation position is allocated to the vehicle allocation position is performed (step S204). After that, the process ends.

On the other hand, in step S203, when the vehicle allocation request is received at 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, the first vehicle allocation mode in which the vehicle 10 assigned to the divided area where the vehicle allocation position exists is allocated to the vehicle allocation position is performed (step S205).

When the first vehicle allocation mode is performed, the adjustment unit 28 determines whether or not the vehicle allocation position is within the area of the divided area expanded by changing the boundary position (step S206). When the adjusting unit 28 determines that the vehicle is within the expanded area (Yes in step S206), 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 between the two division areas. The boundary region of both divided areas is moved so as to be performed (step S207). After that, the process ends. If it is determined in step S206 that the area is not within the expanded area (No in step S206), the process ends.

As described above, in the vehicle allocation system SYS, the vehicle allocation method, and the vehicle allocation program according to the present embodiment, the vehicle allocation system is divided into a plurality of division areas AR1 to AR3, and a predetermined number of vehicles 10 are assigned to each division area in the business area AR. , When a vehicle allocation request is made to a vehicle allocation position in the first division area among a plurality of division areas, the first vehicle allocation mode in which the empty vehicle 10 assigned to the first division area is allocated to the vehicle allocation position, or The vehicle allocation instruction unit 27 performs the second vehicle allocation mode in which the empty vehicle 10 existing at the position closest to the vehicle allocation position is allocated to the vehicle allocation position, and is assigned to the second division area different from the first division area in the second vehicle allocation mode. When the vehicle 10 to be assigned is allocated to the vehicle allocation position, the number of vehicles 10 assigned to the first division area between the first division area and the second division area per unit size is determined by the adjustment unit 28. Is relatively reduced, and the number of vehicles 10 assigned to the second division area per unit area is relatively increased.

Specifically, the boundary position of the plurality of divided areas can be changed, the first divided area is relatively expanded between the first divided area and the second divided area, and the second divided area is relative to each other. The boundary position is changed by the adjusting unit 28 so as to be reduced.

According to the above configuration, the range in which the vehicle allocation request by telephone 40 can be accepted for the first division area can be expanded, and the range in which the vehicle allocation request by telephone 40 can be accepted for the second division area can be narrowed. Therefore, the chances of vehicle allocation in the first division area can be relatively increased, and the opportunities for vehicle allocation in the second division area can be relatively reduced. Therefore, it is possible to adjust the profit between the second divided area side, which has gained profit from the area-crossing vehicle allocation mode, and the first divided area side, which has lost the opportunity to allocate vehicles. As a result, it is possible to prevent the fairness of the number of vehicles allocated between the divided areas from being impaired.

Further, in the vehicle allocation system SYS, the vehicle allocation method, and the vehicle allocation program according to the present embodiment, a plurality of vehicle allocation areas AR are divided into a plurality of division areas AR1 to AR3, and a predetermined number of vehicles 10 are assigned to each division area. When a vehicle allocation request is made to a vehicle allocation position in the first division area of the division area, the vehicle 10 in the vacant state assigned to the first division area is allocated to the allocation position in the first vehicle allocation mode or the vehicle allocation position. The vehicle allocation instruction unit 27 performs the second vehicle allocation mode in which the empty vehicle 10 existing at the nearest position is allocated to the vehicle allocation position, and the first division area among the plurality of division areas is different from the first division area. Within the expanded area of the first division area after the boundary position is changed so that the first division area is relatively expanded and the second division area is relatively reduced with respect to the division area. When a vehicle allocation request is made to the vehicle allocation position and the first vehicle allocation mode is performed in response to the vehicle allocation request, the first division area is relatively reduced between the first division area and the second division area. , The boundary position is changed by the adjusting unit 28 so that the second division area is relatively enlarged.

According to the above configuration, the range in which the vehicle allocation request by telephone 40 can be accepted for the second division area can be expanded, and the range in which the vehicle allocation request by telephone 40 can be accepted for the first division area can be narrowed. Therefore, the chances of vehicle allocation in the second division area can be relatively increased, and the opportunities for vehicle allocation in the first division area can be relatively reduced. Therefore, it is possible to adjust the profit between the first division area side that gained the profit by changing the boundary position and the second division area side that lost the opportunity to dispatch the vehicle. As a result, it is possible to prevent the fairness of the number of vehicles allocated between the divided areas from being impaired.

In the vehicle allocation system SYS according to the present embodiment, the division area information management unit 23 for storing a plurality of candidates for the changed boundary position is provided, and the adjustment unit 28 selects one candidate from the plurality of candidates. Set the boundary position after the change. As a result, the boundary position can be set smoothly.

In the vehicle allocation 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 area-crossing vehicle allocation mode or the expanded area vehicle allocation 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 the vehicle has been assigned or lost, so that the profits between the divided areas can be adjusted more appropriately.

In the vehicle allocation system SYS according to the present embodiment, the vehicle allocation instruction unit 27 performs the first vehicle allocation mode when receiving the vehicle allocation request from the vehicle allocation terminal 31 of the vehicle allocation center 30, and is a terminal different from the vehicle allocation terminal 31 and is a vehicle. When the vehicle allocation request is received from the mobile terminal 50 capable of grasping the position of 10, the second vehicle allocation mode is performed. As a result, it is possible to adjust the profit between the second divided area side, which has gained a profit from the vehicle allocation request of the mobile terminal 50, and the first divided area side, which has lost the opportunity to allocate a vehicle.

In the above-described embodiment, when the area-crossing vehicle allocation mode is performed, the first division area is relatively expanded between the first division area and the second division area, and the second division area is relative to each other. The case where the boundary position of the divided area is changed so as to be reduced as an example has been described as an example, but the present invention is not limited to this. For example, when the area-crossing vehicle allocation mode is performed, the adjustment unit 28 relatively reduces the number of vehicles 10 assigned to the first division area between the first division area and the second division area. Adjustments may be made to increase the number of vehicles assigned to the second division area relatively.

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

Therefore, as shown in FIG. 11, the adjusting unit 28 makes a part (for example, one or several vehicles) of the vehicles 10 belonging to the divided area AR1 belong to the divided area AR2. In FIG. 11, the vehicle 10a is assigned to the divided area AR2 as an example, but the present invention is not limited to this, and the vehicles 10b and 10c may be assigned to the divided area AR1. By changing the affiliation of the vehicle 10 in this way, the number of vehicles 10 assigned to the divided area AR1 is relatively reduced, and the number of vehicles assigned to the divided area AR2 is relatively increased. After that, when there is a vehicle allocation request from the telephone 40 of the divided area AR2, the vehicle allocation instruction unit 27 gives priority to the vehicle 10 (vehicle 10a) whose affiliation has changed to the divided area AR2.

As a result, in the divided area AR1, the number of vehicles 10 per unit area is reduced. Therefore, it is possible to increase the expected value for each vehicle 10 belonging to the divided area AR1 to receive the vehicle allocation in response to the vehicle allocation request by the telephone 40. On the other hand, in the 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 the vehicle allocation in response to the vehicle allocation request by the telephone 40. Therefore, the chances of dispatching the individual vehicles 10 belonging to the divided area AR1 can be relatively increased, and the opportunities of dispatching the individual vehicles 10 belonging to the divided area AR2 can be relatively reduced.

FIG. 12 is a diagram showing another mode of adjustment by the adjusting unit 28. Note that FIG. 12 shows a vehicle allocation position (for example, a mobile terminal 53) in which the vehicle 10 (for example, vehicle 10b) assigned to the divided area AR1 exists in the divided area AR2 after the affiliation of the vehicle 10 is changed according to FIG. This is an example of a case where the vehicle allocation mode across the area is performed. In this case, the vehicle 10 in the divided area AR1 will benefit from the vehicle allocation request of the mobile terminal 50, but the vehicle 10 in the divided area AR2 will lose the opportunity to allocate the vehicle.

Therefore, as shown in FIG. 12, the adjusting unit 28 makes a part (for example, one or several vehicles) of the vehicles 10 belonging to the divided area AR2 belong to the divided area AR1. In FIG. 12, the vehicle 10a is assigned to the divided area AR1 as an example, but the present invention is not limited to this, and the vehicles 10d, 10e, and 10f may be assigned to the divided area AR1. By changing the affiliation of the vehicle 10 in this way, 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. After that, when there is a vehicle allocation request from the telephone 40 of the divided area AR1, the vehicle allocation instruction unit 27 gives priority to the vehicle 10 (vehicle 10a) whose affiliation has changed to the divided area AR1.

As a result, in the divided area AR2, the number of vehicles 10 per unit area is reduced. Therefore, it is possible to increase the expected value for each vehicle 10 belonging to the divided area AR2 to receive the vehicle allocation in response to the vehicle allocation request by the telephone 40. On the other hand, in the 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 the vehicle allocation in response to the vehicle allocation request by the telephone 40. Therefore, the chances of dispatching the individual vehicles 10 belonging to the divided area AR2 can be relatively increased, and the opportunities of dispatching the individual vehicles 10 belonging to the divided area AR1 can be relatively reduced.

The vehicle allocation method shown in FIGS. 11 and 12 will be described with reference to FIG. FIG. 13 is a flowchart showing another example of the vehicle allocation method. As shown in FIG. 13, the vehicle allocation server 20 receives a vehicle allocation request from the vehicle allocation center 30 or the mobile terminal 50 (step S301). When the vehicle allocation request is received at 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, when the receiving destination 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 adjusting unit 28 determines whether or not the division area where the vehicle allocation position exists and the division area to which the dispatched vehicle 10 belongs are different (step S305). When the adjusting 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 reduced between the two divided areas, and the vehicle is allocated. 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 vehicle 10 belongs is relatively increased (step S306). After that, the process ends. If it is determined in step S305 that the two division areas are not different (No in step S305), the process ends.

In this way, when the area-crossing vehicle allocation mode is performed, the adjusting unit 28 relatively reduces the number of vehicles 10 assigned to the first division area between the first division area and the second division area. The number of vehicles assigned to the second division area is relatively increased. As a result, it is possible to adjust the profit between the second divided area side, which has gained profit from the area-crossing vehicle allocation mode, and the first divided area side, which has lost the opportunity to allocate vehicles. As a result, it is possible to prevent the fairness of the number of vehicles allocated between the divided areas from being impaired.
