Description

  The present invention relates to a vehicle allocation method for a vehicle allocation system for distributing mobile stations to passengers.

  In general, for example, an automatic vehicle monitoring (hereinafter referred to as AVM) system is a system that manages the dispatch of mobile stations such as taxis. This AVM system is used in a management center that manages the dispatch of mobile stations.

  The mobile station grasps the current position information by a Global Positioning System (hereinafter referred to as GPS). Each mobile station uses a polling signal to base the position information obtained by GPS, dynamic information indicating the state of the mobile station such as an actual vehicle, an empty vehicle, and standby, and other information (for example, moving direction, moving speed, and accident information). The data is periodically transmitted to the management center via the station.

  The management center collects the current position information, dynamic information, and other information of the mobile station by the AVM system, and manages these for dispatch. Specifically, the management center polls all mobile stations in turn, and collects current location information, dynamic information, and other information of all mobile stations. The collected location information, dynamic information, and other information are, for example, passenger information having the passenger name, address, telephone number, and requested dispatch location (hereinafter referred to as a dispatch location) used at the management center by the AVM system. It is managed with.

As described above, the management center manages the current position information, the dynamic information, the other information, and the passenger information, thereby constructing a vehicle allocation system that manages the allocation of mobile stations.
When a passenger requests a dispatch to the management center, the management center can reach the dispatch location requested by the passenger the fastest based on the current location information and dynamic information of the mobile station being managed. And search for an empty mobile station in which no passenger is on board. Then, the management center instructs the corresponding mobile station to dispatch a vehicle using a polling signal. Upon receiving the instruction, the mobile station transmits an ACK (return signal) to the management center via the base station. The management center instructs the passenger information to the mobile station that has received the ACK, and directs it to the dispatching point (where the mobile station is to be brought) requested by the passenger.

  In addition, for example, in Patent Document 1, even when a mobile station in an empty state cannot be found, the destination position (passenger's destination, place where the passenger gets off) of a mobile station already carrying a passenger (in the actual vehicle state) is newly added. If the new passenger who requested the vehicle allocation is at or near the vehicle allocation location requested by the new passenger and can reach the vehicle allocation location requested by the new passenger the fastest, the mobile station in the actual vehicle state is assigned to the new passenger. A vehicle allocation system as a vehicle allocation candidate for is disclosed.

JP 2008-78784 A

A vehicle allocation method in the general vehicle allocation system described above is shown in FIGS. 6A to 6C. 6A to 6C, the management center and the base station are not shown for simplification of illustration.
As shown in FIG. 6A, the passenger a who requested the dispatch, the mobile station 20a in an empty state, and a mobile station in an actual vehicle state placed on a position closer to the passenger a than the mobile station 20a but carrying other passengers 20b exists. At this time, the mobile station 20a is instructed to dispatch a vehicle as shown in FIG. 6A by a management center (not shown) so that the passenger a heads for the dispatching point 61 that requested the dispatch. That is, the mobile station 20 is dispatched to the dispatch point 61 for the passenger a by a management center (not shown).

However, once the mobile station to be dispatched to the passenger a who requested the dispatch is determined as the mobile station 20a, the mobile station 20b disposed closer to the passenger a than the mobile station 20a is empty as shown in FIG. 6B. Even if the vehicle can be dispatched, the mobile station to be dispatched is not changed from the mobile station 20a to the mobile station 20b.
Therefore, as shown in FIG. 6B, when a passenger b requests a dispatch to a dispatch point 62 in the same region 63 as the dispatch point 61 where the passenger a requested a dispatch after the passenger a, the mobile station 20b which is empty Is instructed to dispatch by a management center (not shown) so that the passenger b goes to the dispatching point 62 that requested the dispatch. That is, the mobile station 20b is dispatched to the dispatch point 62 for the passenger b by a management center (not shown).

  Therefore, as shown in FIG. 6C, the mobile station 20b is dispatched first to the passenger b who requested the dispatch after the passenger a. That is, as shown in FIG. 6B, since the mobile station 20b is located closer to the same area 63 than the mobile station 20a, before the mobile station 20a reaches the passenger a, the mobile station 20b As shown in FIG. 4, there is a case in which the passenger b who has requested the dispatch is reached after the passenger a. In this way, there is a discrepancy in dispatch.

  When a large number of dispatches are requested from the same area as shown in FIG. 6B at a venue where an event is held, in the morning or evening or in the rain, a difference in dispatch occurs as described above, and later dispatch as shown in FIG. 6C. The waiting time for the dispatch of the passenger a who requested the vehicle dispatch before the passenger b who requested the vehicle becomes longer, and there is a risk that the identification of the passenger for the vehicle dispatch (in this case, the passenger a) will be lowered.

  If the mobile station dispatched to the passenger a changes from the mobile station 20a to the mobile station 20b from the viewpoint of reducing the waiting time for the dispatch of the passenger a in the absence of the passenger b, the movement in which the dispatch is cancelled. The business efficiency of the station 20a is lowered, and there is a possibility that the vehicle cannot be efficiently allocated.

  Therefore, in view of the above circumstances, an object of the present invention is to provide a vehicle allocation method for a vehicle allocation system that reduces the waiting time of passengers and efficiently allocates mobile stations.

  In order to achieve the object, the present invention is a vehicle allocation method for a vehicle allocation system comprising at least a first mobile station that moves to a first point and a second mobile station that moves to a second point, A first distance calculating step for calculating a distance from the current position of the first mobile station to the first point; and a distance from the current position of the second mobile station to the first point. A determination step for comparing the distance calculated by the second distance calculation step, the distance calculated by the first distance calculation step, and the distance calculated by the second distance calculation step, and determining whether or not the vehicle allocation destination needs to be changed. And when it is determined in the determination step that a change of the vehicle destination is necessary, the second mobile station is allocated to the first point, and the first mobile station is allocated to the second mobile station. The allocation of a vehicle allocation system characterized by To provide a method.

  In order to achieve the object of the present invention, the first mobile station has already been dispatched to the first dispatch point for the first passenger who previously requested the dispatch, and the same area as the first dispatch point. , There is an empty second mobile station closer to the area than the first mobile station, and from the second passenger to the second dispatch point in the area after the first passenger. When the vehicle is requested to be dispatched, the first mobile station that has already been dispatched is dispatched to the first dispatch point for the first passenger who has requested the dispatch of the first mobile station. Changing the destination of the first mobile station so that the mobile station of the first mobile station is dispatched to the second dispatch point for the second passenger who requested the dispatch from the rear of the first passenger. A vehicle allocation method for a vehicle allocation system is provided.

  In order to achieve the object of the present invention, the second dispatch point is included in the same area as the first dispatch point, and the first mobile station has reached the first dispatch point.

For example, a dispatch request is received from the management center 300 by a polling signal Po1.

  Each mobile station 200 in the present embodiment is equipped with an operation unit 203 connected to the GPS unit 201 and the wireless communication unit 202. The operation unit 203 is an information terminal for a crew member to perform a response operation to a vehicle allocation request, for example. The operation unit 203 also sends, for example, information on the destination position (destination) of the passenger, a vehicle allocation point where a vehicle is requested (requested) and a vehicle allocation request from the management center 300, and a base station 100 and an antenna 202a from the management center 300. And the wireless communication unit 202. For this reason, the operation unit 203 transmits, for example, a not-shown display unit that displays destination information, a dispatch point, a dispatch request, and current position information in, for example, voice and characters, and an acknowledgment signal described later in response to the dispatch request, for example. And an operation main body (not shown) having an operation button for performing the response operation. The display unit may include, for example, a car navigation system (hereinafter, car navigation system) that displays the current position information generated by the GPS unit 201.

  The management center 300 polls a part or all of the mobile stations 200 via the base station 100 (transmits / receives a polling signal Po1 and a polling response signal Po2). As a result, the management center 300 collects the current position information and dynamic information of the mobile station 200 arranged in the area of the base station 100 and other information such as the moving direction in a predetermined order via the base station 100. ,to manage. This order is, for example, the order of the vehicle numbers of the mobile stations 200 stored in the mobile station list 321a shown in FIG. 3 or the order of responses preset by polling (details will be described later). The mobile station list 321a is stored in a database 302a in the location server 302 shown in FIG.

  Each time the management center 300 performs polling via the base station 100, the management center 300 collects and manages, for example, the updated dynamic information and current position information of the mobile station 200, for example. The updated dynamic information and current position information are sequentially rewritten and managed by a control unit 310 (described later) provided in the management center 300.

  In FIG. 1, the base station 100 is independent from the management center 300, but the base station 100 and the management center 300 can be configured integrally according to the scale of the vehicle allocation system 10. Also, there is at least one base station 100, and each base station 100 is connected to the management center 300 by wire.

  As described above, in the dispatch system 10, the management center 300 transmits a dispatch request (polling signal Po1) to the mobile station 200 via the base station 100, and the management center 300 transmits an ACK signal from the mobile station 200 via the base station 100. Polling is performed to sequentially receive current position information, dynamic information, and (polling response signal Po2).

Next, the management center 300 in the present embodiment will be described in detail with reference to FIGS.
As shown in FIG. 2, the management center 300 includes a computer telephony integration (hereinafter CTI) server 301, a location server 302, an automatic vehicle monitoring server (hereinafter AVM server) 303, a call recording unit 304, and an operation terminal. 305 and a control unit 310 are provided.

  The CTI server 301 is connected to the telephone line 400. The CTI server 301 is provided with the passenger information terminal 500 connected via the telephone line 400, for example, the passenger name, telephone number, address, dispatch point, and the main section (for example, Passenger information 307b such as between the home and the hospital) and the destination location are registered. The passenger information 307b is displayed as shown in FIG. 3 on a display unit 307 provided in an operation terminal 305 described later.

The location server 302 serving as a storage unit stores a database 302a for the mobile station 200 and an incoming vehicle database 302b for the mobile station 200 in the incoming state.
The database 302a stores a mobile station list 321a in which mobile station information is stored by the control unit 310. The database 302a displays the mobile station list 321a on the display unit 307 as shown in FIG. 3 when a request for dispatch is made from the passenger to the management center 300 via the passenger information terminal 500 and the telephone line 400. The mobile station information includes, for example, a vehicle number assigned to each mobile station 200, current movement information of each mobile station 200, and current position information of each mobile station 200. In the mobile station information, for example, the traveling direction information of each mobile station 200, the speed information of each mobile station 200, the destination current position information in which the passenger's destination position is coded, and the passenger's destination position are written in characters. The described destination location area information, a dispatch point, a passenger name, and a time at which a pickup is instructed may be included.
The mobile station list 321a is created by the control unit 310 based on, for example, current position information and dynamic information of the mobile station 200 managed by the control unit 310 described later by polling.

  In the incoming vehicle database 302b, the mobile station information of the mobile station 200 whose movement information is the incoming vehicle is extracted from the database 302a (mobile station list 321a) by the control unit 310, and the mobile station information is stored by the control unit 310. An incoming vehicle list 321b is stored. Since the mobile station information stored in the incoming vehicle list 321b is limited to the mobile station 200 that is the incoming vehicle, the mobile station information is referred to as incoming mobile station information. That is, the incoming vehicle database 302b includes incoming mobile station information of the mobile station 200 whose dynamic information is the incoming vehicle. The incoming mobile station information includes a vehicle number assigned to each mobile station 200, current position information of each mobile station 200, and a dispatch point (a dispatch point of the mobile station 200 requested by the passenger). . Note that the incoming mobile station information may include, for example, the name of the passenger who requested each mobile station 200 to dispatch and the time when each mobile station 200 was instructed to pick up the car. The receiving mobile station information is displayed on the display unit 307 as shown in FIG.

  The location server 302 may not be provided in the small and medium-sized vehicle allocation system 10 having about 200 mobile stations 200, for example. At this time, the AVM server 303 only needs to have the function of the location server 302.

  The AVM server 303 serving as a management unit manages, for example, current position information and dynamic information of the mobile station 200 obtained through the base station 100. In the present embodiment, these pieces of information are collected by the AVM server 303 via the base station 100 by a polling method.

  The call recording unit 304 records the call contents (communication record) in the telephone call between the passenger requesting the dispatch and the operator.

The operation terminal 305 is provided with an input unit 306 and a display unit 307.
For example, as shown in FIG. 3, the display unit 307 displays map information 307 a indicating a dispatch point and the current position of the mobile station 200, and passenger information terminals 500 and telephone lines 400 from passengers registered in the CTI server 301 in advance. When there is a vehicle dispatch request to the management center 300, the passenger information 307b regarding the passenger registered in the CTI server 301 is displayed. As shown in FIG. 3, the display unit 307 displays the mobile station list 321a stored in the database 302a and the incoming vehicle list 321b stored in the incoming vehicle database 302b.

  The input unit 306 inputs passenger information related to a new passenger if, for example, the passenger who requested the dispatch is a new passenger that is not registered in the CTI server 301 in advance. The input unit 306 is also an instruction unit for instructing a change of a vehicle destination to be described later. The input unit 306 inputs a dispatch point of the mobile station 200 requested by the passenger. The input dispatch point is stored in, for example, the mobile station list 321a or displayed on the display unit 203a of the mobile station 200 that has accepted the dispatch request. In addition, since the call content regarding the dispatch request between the operator and the passenger is recorded in the call recording unit 304, the input unit 306 can input passenger information and the like when the operator listens back to the call content at a later date.

The control unit 310 stores (manages), for example, current position information and dynamic information of the mobile station 200 collected via the base station 100 at a desired timing such as polling.
The control unit 310 controls the CTI server 301, the location server 302, the AVM server 303, the call recording unit 304, and the operation terminal 305, and performs the following operations.

  As shown in FIG. 4A, the control unit 310, for example, when the management center 300 is requested to dispatch a vehicle from the passenger A, for example, the mobile station information in the mobile station information stored in the mobile station list 321a stored in the database 302a. Based on the current position information and dynamic information, for example, in an empty state, search for the mobile station 200 located at the shortest distance or distance from the current position of the mobile station 200 to the dispatch point 610 where the passenger A requested the dispatch. To do. This mobile station 200 is referred to as a mobile station 200a having a vehicle number 1. Here, for example, the dynamic information of the mobile station 200b closer to the dispatch point 610 than the mobile station 200a is, for example, an actual vehicle. Therefore, the control unit 310 deletes the mobile station 200b from candidates to be dispatched for the passenger A. The mobile station 200b has a vehicle number 2.

  The control unit 310 issues a vehicle allocation request (vehicle allocation instruction) to the mobile station 200a using the polling signal Po1 via the base station 100. That is, the control unit 310 dispatches the mobile station 200 a to the dispatch point 610 for the passenger A.

  The control unit 310 receives the polling response signal Po2 from the mobile station 200a via the base station 100. Note that the polling response signal Po2 in this case is an acknowledgment signal including an ACK signal (return signal) indicating that the vehicle allocation request is accepted. When the control unit 310 receives the acknowledgment signal from the mobile station 200a within a preset reception time (for example, approximately 5 seconds to approximately 7 seconds), the vehicle allocation is completed.

At this time, the dynamic information of the mobile station 200a is picked up for the passenger A from the empty vehicle as shown in FIG. 3 and FIG. 4B.
Further, when there is a mobile station 200 whose movement information is an incoming vehicle, the control unit 310 stores an incoming vehicle list 321b in which the incoming mobile station information is stored in the incoming vehicle database 302b.

  As shown in FIG. 4B, for example, when the management center 300 is requested to dispatch a vehicle after the passenger A, the control unit 310 stores the mobile station information stored in the mobile station list 321a stored in the database 302a. For example, based on the current position information and dynamic information of the mobile station 200, the distance from the current position of the mobile station 200 to the dispatch point 620 at which the passenger B requested the dispatch or the distance from the current position of the mobile station 200 is the shortest. The mobile station 200 to be searched is searched. This mobile station 200 is referred to as a mobile station 200b. As shown in FIG. 4A, the mobile station 200b has dynamic information when the passenger A requests dispatch, and the passenger information when the passenger B requests dispatch as shown in FIGS. 3 and 4B. Mobile station.

At this time, the control unit 310 determines whether or not the allocation point 620 is included in the same area (the same area 630) as the allocation point 610, for example, in the reception vehicle list 321b stored in the reception vehicle database 302b corresponding to the allocation point 610. The determination is made based on the vehicle allocation point in the stored incoming mobile station information, the vehicle allocation point in the passenger information 307b corresponding to the vehicle allocation point 620, and the map information 307a.
This same area 630 indicates that the vehicle allocation point 620 is located in a desired range, for example, within a radius of 100 m from the vehicle allocation point 610 of the passenger A who requested the vehicle allocation earlier. In other words, the same area 630 includes the dispatch point 610 of the passenger A and the dispatch point 620 of the passenger B.

  If the controller 310 determines that the dispatch point 620 is the same area 630 as the dispatch point 610, the controller 310 determines the mobile station 200a in the mobile station information stored in the mobile station list 321a stored in the database 302a. Based on the current location information or the current location information of the mobile station 200a in the incoming mobile station information stored in the incoming vehicle list 321b stored in the incoming vehicle database 302b and the map information 307a, the mobile station 200a moves to the dispatch point 610. It is determined whether or not it has been reached.

When the control unit 310 determines that the mobile station 200a has not reached the dispatch point 610, the control unit 310, for example, as shown in FIG. 4C, the current position information of the mobile station 200a and the current position information of the mobile station 200b Based on the map information 307a, for example, a distance A from the dispatch point 610 to the current position of the mobile station 200a and a distance B from the dispatch point 610 to the current position of the mobile station 200b are calculated.
At this time, the control unit 310 uses the mobile station information stored in the mobile station list 321a stored in the database 302a or the incoming mobile station information stored in the incoming vehicle list 321b stored in the incoming database 302b. The current position information of 200a is calculated, and the current position information of the mobile station 200b is calculated based on the mobile station information stored in the mobile station list 321a stored in the database 302a.

  Then, as shown in FIG. 4C, the control unit 310 compares the distance A and the distance B, and determines whether or not the distance B is shorter than the distance A, that is, the current position of the mobile station 200b is larger than the current position of the mobile station 200a. It is determined whether or not it is close to the dispatch point 610.

  If the control unit 310 determines that the distance B is shorter than the distance A by a certain distance (for example, 1 km) or more, the control unit 310 sends the polling signal Po1 to the mobile station 200a via the base station 100 as shown in FIG. 4D. Is used to instruct a vehicle allocation change request (vehicle allocation change instruction), that is, a passenger change and a destination change instruction. More specifically, the control unit 310 uses the polling signal Po1 via the base station 100 to change the passenger for the incoming vehicle from the passenger A to the passenger B to the mobile station 200a. To change to the dispatch point 620. That is, the control unit 310 instructs the mobile station 200a to change the vehicle allocation so that the mobile station 200a is allocated to the vehicle allocation point 620 for the passenger B.

  Further, the control unit 310 issues a vehicle allocation request (vehicle allocation instruction) to the mobile station 200b using the polling signal Po1 via the base station 100. That is, the control unit 310 dispatches the mobile station 200b to the dispatch point 610 for the passenger A.

  Then, the control unit 310 receives the polling response signal Po2 from the mobile stations 200a and 200b via the base station 100, respectively. Note that the polling response signal Po2 in this case is an acknowledgment signal including an ACK signal (return signal) indicating that the vehicle allocation request is accepted. When the control unit 310 receives this approval signal from the mobile stations 200a and 200b within a reception time (for example, approximately 5 seconds to approximately 7 seconds) that is set in advance to receive the approval signal, the vehicle allocation is completed. Become.

  In addition, the dynamic information of the mobile station 200a serves as a passenger for the passenger B, and the dynamic information of the mobile station 200b serves as a passenger for the passenger A from an empty car.

  As described above, the control unit 310 has already allocated the mobile station 200a to the allocation point 610 for the passenger A who has requested the allocation in advance, and the mobile station 200a is around the same area 630 that is the same area as the allocation point 610. When the mobile station 200b in an empty state exists near the same area 630, and when this passenger A requests a vehicle from the same area 630, another passenger B requests a vehicle distribution point 620 in the same area 630. For the passenger B who has dispatched the mobile station 200a in the empty state to the dispatch point 610 for the passenger A who has requested the dispatch first, and the mobile station 200a which has already been dispatched is requested to be dispatched after the passenger A. The destination of the mobile station 200a is changed so that the vehicle is allocated to the vehicle allocation point 620.

  When the dispatch point 620 is included in the same region 630 that is the same region as the dispatch point 610, and the mobile station 200a has not reached the dispatch point 610, the control unit 310 determines the current position of the mobile station 200a from the dispatch point 610. When the distance B is shorter than the distance A by a predetermined distance or more, the control unit 310 moves as described above, and the distance A from the dispatch point 610 to the current position of the mobile station 200b is compared. The allocation destination of the mobile station 200a is changed so that the station 200b is allocated to the allocation point 610 and the mobile station 200a is allocated to the allocation point 620.

In other words, the control unit 310 includes at least the mobile station 200a that moves to the dispatch point 610 that is the first point and the mobile station 200b that moves to the dispatch point 620 that is the second point. The distance A from the current position to the dispatch point 610 is calculated, the distance B from the current position of the mobile station 200b to the dispatch point 610 is calculated, the distance A and the distance B are compared, and the destinations of the mobile stations 200a and 200b If it is determined whether or not a change is required and it is determined that a change of the destination is necessary, the mobile station 200b is allocated to the allocation point 610, and the mobile station 200a is allocated to the allocation point 620.
As described above, the necessity of changing the dispatch destination is, for example, whether the distance B is shorter than the distance A, that is, whether the current position of the mobile station 200b is closer to the dispatch point 610 than the current position of the mobile station 200a. Indicates whether or not.

Next, a vehicle allocation method by the vehicle allocation system 10 in the present embodiment will be described with reference to FIGS.
As shown in FIG. 4A, the management center 300 is requested to dispatch a vehicle from the passenger A to the vehicle allocation point 610 that is the vehicle allocation destination via the passenger information terminal 500 and the telephone line 400 (Step 1).

  In the management center 300, as shown in FIG. 3, the display unit 307 is stored in the database 302a by the control unit 310 and the mobile station list 321a in which the mobile station information is stored, and passengers registered in the CTI server 301. And passenger information 307b. At this time, the display unit 307 may display the map information 307a. At this time, the dispatch point 610 is included in the passenger information 307b and the map information 307a.

  Next, as shown in FIG. 4A, the control unit 310, for example, from the current position of the mobile station 200 to the dispatch point 610 in an empty state based on the current position information and dynamic information of the mobile station 200 in the mobile station list 321a. The mobile station 200 located at the position where the distance or the distance is the shortest is searched (Step 2). The mobile station 200 corresponding to this search is referred to as a mobile station 200a having a vehicle number 1.

  At this time, in the present embodiment, as shown in FIG. 4A, for example, the dynamic information of the mobile station 200b closer to the dispatch point 610 than the mobile station 200a is, for example, an actual vehicle. Therefore, the control unit 310 deletes the mobile station 200b from candidates to be dispatched for the passenger A. The mobile station 200b has a vehicle number 2.

  Then, as shown in FIG. 4A, the control unit 310 instructs the mobile station 200a to dispatch the mobile station 200a to the dispatch point 610 for the passenger A. Therefore, it becomes an incoming car (Step 3). At this time, the mobile station list 321a stores that the allocation point of the mobile station 200a is the allocation point 610.

  At this time, the control unit 310 stores the incoming vehicle list 321b storing the incoming mobile station information in the incoming vehicle database 302b as shown in FIG. 3 (Step 4). The display unit 307 causes the control unit 310 to display the incoming vehicle list 321b stored in the incoming vehicle database 302b as shown in FIG. At this time, it is stored in the incoming vehicle list 321b that the allocation point of the mobile station 200a is the allocation point 610.

  Next, as illustrated in FIG. 4B, the management center 300 is requested to dispatch the vehicle from the passenger B to the vehicle allocation point 620 as the vehicle allocation destination via the passenger information terminal 500 and the telephone line 400 (Step 5). At this time, the dispatch point 620 is included in the passenger information 307b and the map information 307a.

  At this time, it is assumed that the dynamic information of the mobile station 200b, which was an actual vehicle, is already empty as shown in FIGS. 3 and 4B.

  As shown in FIG. 4B, the control unit 310, for example, from the current position of the mobile station 200 to the dispatch point 620 in an empty state based on, for example, the current position information and dynamic information of the mobile station 200 in the mobile station list 321a. The mobile station 200 located at the position where the distance or the distance is the shortest is searched (Step 6). The mobile station 200 corresponding to this search is referred to as the mobile station 200b described above. At this time, the mobile station 200b is a vehicle allocation candidate.

  Next, as illustrated in FIG. 4B, the control unit 310 determines whether or not the dispatch point 620 is included in the same region (the same region 630) as the dispatch point 610, for example, with the mobile station list 321a corresponding to the dispatch point 610. The determination is made based on the passenger information 307b corresponding to the vehicle allocation point 620 and the map information 307a. (Step 7). That is, the control unit 310 determines whether or not the dispatch point 620 is located in a desired range such as within a radius of 100 m from the dispatch point 610.

  When the control unit 310 determines that the allocation point 620 is the same area as the allocation point 610 (Step 7: YES), the control unit 310 indicates that the mobile station 200a has reached the allocation point 610 as shown in FIG. 4B. Whether or not (Step 8). The control unit 310 makes this determination based on the current position information of the mobile station 200a in the mobile station list 321a or the current position information of the mobile station 200a in the pick-up list 321b and the map information 307a.

When the control unit 310 determines that the mobile station 200a has not reached the dispatch point 610 (Step 8: NO), the control unit 310, for example, as shown in FIG. The distance A and the distance B are calculated based on the current position information of the station 200b and the map information 307a. (Step 9).
This Step 9 is a first distance calculation step for calculating the distance A from the current position of the mobile station 200a to the dispatch point 610, and a second distance for calculating the distance B from the current position of the mobile station 200b to the dispatch point 610. It is a calculation step.

Then, as shown in FIG. 4C, the control unit 310 compares the distance A and the distance B, and whether the distance B is shorter than the distance A by a predetermined distance, that is, the current position of the mobile station 200b is the current position of the mobile station 200a. It is determined whether or not the vehicle is closer to the dispatch point 610 (Step 10).
This Step 10 is a determination step that compares the distance A calculated in the first distance calculation step with the distance B calculated in the second distance calculation step and determines whether or not it is necessary to change the allocation destination. Show.

  When the control unit 310 determines that the distance B is shorter than the distance A (Step 10: YES), the control unit 310 sends a polling signal Po1 to the mobile station 200a via the base station 100 as shown in FIG. 4D. It is used to instruct a vehicle allocation change request (vehicle allocation change instruction), that is, a passenger change and a destination change instruction. More specifically, the control unit 310 uses the polling signal Po1 via the base station 100 to change the passenger for the incoming vehicle from the passenger A to the passenger B to the mobile station 200a. To change to the dispatch point 620. This fact is transmitted, for example, by voice and text on a display unit (not shown) of the mobile station 200. (Step 11).

  Further, as shown in FIG. 4D, the control unit 310 makes a vehicle allocation request (vehicle allocation instruction) to the mobile station 200b using the polling signal Po1 via the base station 100. That is, the control unit 310 dispatches the mobile station 200b to the dispatch point 610 for the passenger A (Step 12).

Then, the dynamic information of the mobile station 200a is picked up for the passenger B, and the dynamic information of the mobile station 200b is picked up for the passenger A from the empty car.
In Step 11 and Step 12, when it is determined that the destination change is necessary in the determination step in Step 10 (Step 10: Yes), the mobile station 200b is allocated to the allocation point 610, and the mobile station 200a is allocated to the allocation point 620. It shows that.

  It should be noted that in Step 7, the allocation point 620 is not the same area 630 as the allocation point 610 (Step 7: NO), the mobile station 200a has already reached the allocation point 610 in Step 8 (Step 8: YES), and the mobile station 200a in Step 10 When moving quickly and the distance B becomes longer than the distance A (Step 10: NO), the control unit 310 does not change the destination of the mobile station 200a as shown in Step 11 and Step 12, and the mobile station 200b is dispatched to the dispatch point 620 (Step 13).

As described above, in this embodiment, the mobile station 200a is already allocated to the allocation point 610 for the passenger A who has requested the allocation in advance, and the mobile station 200a is located in the vicinity of the same area 630 that is the same area as the allocation point 610. When the mobile station 200b in an empty state exists near the same area 630, and when this passenger A requests a vehicle from the same area 630, another passenger B requests a vehicle distribution point 620 in the same area 630. Then, the control unit 310 allocates the mobile station 200b in an empty state to the allocation point 610 for the passenger A who first requested the allocation, and requests the allocation of the mobile station 200a that has already been allocated after the passenger A. The dispatch destination of the mobile station 200a is changed so as to dispatch to the dispatch point 620 for the passenger B.
Further, in this embodiment, when the dispatch point 620 is included in the same region 630 that is the same region as the dispatch point 610 and the mobile station 200a has not reached the dispatch point 610, the control unit 310 causes the distance A and the distance B to be When the distance B is shorter than the distance A by a predetermined distance or more, the mobile station 200a is arranged so that the mobile station 200b is allocated to the allocation point 610 by the control unit 310 and the mobile station 200a is allocated to the allocation point 620. Is changed by the control unit 310.

  That is, in this embodiment, the distance A and the distance B are calculated, compared with the distance A and the distance B, the necessity of changing the vehicle destination is determined based on the comparison result, and it is determined that the vehicle destination needs to be changed. In this case, the mobile station 200b is dispatched to the dispatch point 610, and the mobile station 200a is dispatched to the dispatch point 620.

Thereby, in this embodiment, when a large number of dispatches are requested from the same area such as a venue where an event is held or a taxi stand in front of the station, it is possible to prevent a difference in dispatch, that is, the passenger A who requested the dispatch first. It is possible to prevent the mobile station 200 from being dispatched to the passenger B who later requested the dispatch.
Thereby, in this embodiment, since the mobile station 200b instead of the mobile station 200a is dispatched to the passenger A, the waiting time of the passenger A can be reduced as a result rather than the mobile station 200a being dispatched.

  And by this, in this embodiment, since it can prevent being dispatched to the passenger B previously, it can prevent that the mentality to the passenger (in this case passenger A) with respect to a dispatch falls.

Moreover, if the mobile station 200 dispatched to the passenger A changes from the mobile station 200a to the mobile station 200b in the state where the passenger B does not exist, the business efficiency of the mobile station 200a whose dispatch has been canceled is reduced. However, in the present embodiment, the mobile station 200 to which the vehicle is allocated is changed only when the vehicle allocation point 610 and the vehicle allocation point 620 included in the same region (the same region 630) as the vehicle allocation point 610 are requested, and the passenger The number of cars and the number of dispatches are the same.
Further, in the present embodiment, when a passenger B is requested to dispatch and searches for a mobile station, the mobile station 200b located closest to the dispatch point 610 is dispatched to the dispatch point 610, and the next to the mobile station 200b. The mobile station 200 located at a position close to the vehicle allocation point 610, the vehicle allocation point 620 or the same area 630 is not allocated to the vehicle allocation point 620, and the allocation of the mobile station 200a is not canceled. In this embodiment, the mobile station 200a is searched without changing the allocation of the mobile station 200a and the allocation of the mobile station 200a is maintained, and the allocation of the mobile station 200a and the mobile station 200b is changed and instructed.
Therefore, in the present embodiment, it is possible to prevent the mobile station 200 from being canceled from being dispatched, to efficiently allocate the mobile station 200 without waste, and to improve the business efficiency of the mobile station 200.

  In the present embodiment, the number of passengers is two passengers A and B, and the number of mobile stations 200 is two, the mobile station 200a and the mobile station 200b. However, these numbers may be the same as each other. There is no limitation.

  Further, in this embodiment, after the destination of the mobile station 200a is changed to the passenger B and the destination 620 and the destination of the mobile station 200b is set to the passenger A and the destination 610, the destination is further illustrated from the passenger C in the same region 630. Suppose that there is a request for dispatch at a place where a vehicle is not dispatched. In this case, as in the case of the mobile station 200b, the control unit 310 newly searches the mobile station 200c in an empty state in which the distance from the current position to the dispatch point is the shortest. If the mobile stations 200a and 200b have not arrived at the dispatch points 620 and 610, respectively, the control unit 310 calculates the distance from the current position of each mobile station to the dispatch point requested by the passenger C, for example. Change the dispatch.

  In the present embodiment, the distance A and the distance B are compared by the control unit 310. However, the present invention is not limited to this. For example, the respective predicted arrivals at which the mobile station 200a and the mobile station 200b arrive at the dispatch point 610, respectively. Times may be compared. The object to be compared is not particularly limited.

  Further, in this embodiment, when it is determined that the distance B is shorter than the distance A, the vehicle allocation is replaced. However, the distances A and B are not more than desired distances, for example, the distance A is 150 m and the distance B is 100 m. In addition, when the mobile stations 200a and 200b are approaching the dispatch point 610, business efficiency can be improved by dispatching the mobile station 200b to the passenger B without replacing the dispatch. Of course, this point is the same even if the distance is replaced with the above-mentioned predicted time.

  Further, in the present embodiment, when the difference between the distance A and the distance B is less than a desired distance, for example, 50 m, the allocation of the mobile station 200b to the passenger B without replacing the allocation as described above, Efficiency can be improved. Of course, this point is the same even if the distance is replaced with the above-mentioned predicted time.

  Further, in the present embodiment, after the control unit 310 changes the allocation, even when the control unit 310 recognizes, for example, a traffic jam based on the current location information and speed information of the mobile station 200, for example, good.

  Further, in the present embodiment, when the passengers A and B request the vehicle allocation, the mobile station 200 in the empty vehicle state (dynamic information) is searched. However, the present invention is not limited to this. For example, an actual vehicle state such as a vehicle scheduled to be empty However, if the destination is the same region 630, it may be added to the search candidate.

  Further, in this embodiment, even if the mobile station 200a has not reached the dispatch point 610 in Step 8, if the mobile station 200a is approaching the desired distance to the dispatch point 610, the control unit 310 does not change the dispatch. Also good. In other words, when the mobile station 200a is away from the dispatch point 610 by a desired distance, Step 8: No, the process proceeds to Step 9, and the control unit 310 changes the dispatch.

In this embodiment, the mobile station 200b is instructed to change the allocation after instructing the mobile station 200a to change the allocation. However, the order is not limited.
In the present embodiment, prior to instructing the mobile station 200b located on the side closer to the dispatch point 610 to dispatch the vehicle, instructing to change the dispatch to the mobile station 200a located far from the dispatch point 610, The mobile station 200a can be notified of the change of the vehicle assignment at an early stage, and the mobile station 200a can be moved to the vehicle assignment point 620 with a margin.
Further, in the present embodiment, by instructing the mobile station 200b located on the side closer to the vehicle dispatch point 610 to dispatch the vehicle, the vehicle station 200b located on the side closer to the vehicle dispatch point 610 is instructed prior to the instruction to change the vehicle allocation to the mobile station 200a located far from the vehicle dispatch point 610 Since the mobile station 200b can be quickly dispatched to the dispatch point 610, the waiting time of the passenger A can be further shortened.

  Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment.
