Next, the operation will be described with reference to FIGS. 4 to 11. FIG. 4 is a flow chart for explaining the operation on the side of the center 1, and FIG. 5 is a flow chart for explaining the local polling process. 6 is a diagram showing an example of a display screen before local polling, FIG. 7 is a diagram showing an example of a format of a message transmitted to a taxi at the time of local polling, and FIG. 8 is a timing chart at the time of local polling. FIG. 9 is a diagram showing an example of a display screen after local polling. 10 is a flowchart for explaining the operation on the taxi side, and FIG. 11 is a diagram showing an example of a display screen around the customer position displayed on the taxi side.

First, when a customer makes a vehicle allocation request, this customer position is input by the operating device 16, and the customer position is transmitted from the main controller 10 to the sub controller 20. The sub-controller 20 determines the map database 2 based on the customer position.
The map data around the customer position is read out from No. 2 and the map already displayed on the display 21 is switched to display the around the customer position (steps S1 to S3). A map is always displayed on the display 21 for operation management.

After that, the main controller 10 executes a local polling process centered on the customer position (step S).
4). The operation status of each taxi when the local polling process is started is shown in FIG. In FIG. 6, M-
1 to M-7 indicate taxi positions representing respective taxis 2 ... by car numbers, and within the radius R centering on the customer position (indicated by CP), currently taxi positions M-2, M- 3, M-
The operation of taxis of vehicle numbers “5”, “32”, and “12” corresponding to No. 4 is displayed.

When the local polling process shown in FIG. 5 is entered, as shown in FIG. 6, a standby vehicle or an empty taxi (vehicle) that can instruct vehicle allocation to a local area with a radius R centered on the customer position CP. Number) is executed. Therefore, the main controller 10 first sets the initial value of the radius R to 500 m and detects taxis existing within the radius of 500 m from the taxi position (step S2).
1). In the example of FIG. 6, vehicle numbers “5”, “32”, “12”
The taxi is located within a radius of 500m and can be dispatched. If no taxi that can direct vehicle allocation is detected within this radius of 500 m, the area is further expanded and the radius is n (n is a parameter).
It is detected whether there is a waiting vehicle or an empty taxi within Km (step S22). If it cannot be detected within this radius nKm, the actual vehicle, that is, the taxi currently renting is also detected as the target of the dispatch instruction, and if it cannot be detected, the whole area (also represented by the radius R) is not detected. ) Is targeted (step S
23).

In this way, when the area for outputting the local polling (or overall polling) signal is determined, the telegram 70 shown in FIG. 7 is set according to the radius R indicating the area. This telegram 70 includes a local polling ID indicating a radius R for determining the area for transmitting the polling signal.
71, position information 72 indicating the longitude and latitude of the center 1, and a vehicle number 73 of a taxi to be polled are set. In the car number 73, the car numbers “32”, “12” ... Are set in order from the car number “5” of the taxi (taxi position M-2) near the customer position CP in the positional relationship of FIG. 6 ( Step S24).

As described above, when the polling condition is set and the local polling (or the global polling) is started (step S25), as shown in FIG. 8, the polling response indicates the vehicle corresponding to the taxi position M-2. Number "5"
From the taxi in the order, the car number “32” corresponding to the taxi position M-3 and the car number “1” corresponding to the taxi position M-4
2 ″ ... in order of operation management information m-2, m-3, m-4
... is reported. By the way, the first incoming call after polling is the operation management information m-1 by self-calling, which is the vehicle number "2" corresponding to the taxi position M-1.
It is from a 5 ”taxi, but this is also included in the dispatch instruction target and its operation management information is in RAM (main controller 10).
(Step S5).

As a result, there is a change in the taxi position around the customer position CP after polling as shown in FIG. 9, which is displayed on the display 21. Next, this customer position CP
With a short route between and each taxi location, or
Several taxis (eg 5
The process of selecting is executed.

At this time, first, a route between the customer position CP and the taxi position reported by polling (including self-calling) is set for each taxi, and the route from the taxi position to the customer position CP is set according to each route. The required time is calculated (step S6). As a result, the taxi with the vehicle number at the taxi position that can reach the earliest takes the shortest route, and is therefore the first vehicle allocation target. According to this procedure, up to the fifth priority is set. Note that road conditions (whether there are rivers or railroad tracks, etc.) are also factors when setting the order, and even if the taxi has the same or slightly longer route length than other taxis, When the vehicle fare will be cheaper at the time of the vehicle, the priority of the taxi with the lower vehicle fare will be given first. The setting of this order also includes elements such as the direction of movement of each taxi, and the taxi that is currently approaching the customer position CP and the taxi that is away from the customer position CP are Prioritize first.

As a result, in the example of FIG. 9, the taxi position M-2 of the car number "5" is close to the customer position, and the taxi position M-1 of the car number "25" having the same shortest route is. Because they are far apart, the first place will be the taxi with the car number "5" and the second place will be the taxi with the car number "25". Subsequently, the third and subsequent vehicles are taxis with the vehicle number “12” ... And the vehicle dispatching order of these is stored in the RAM (main controller 10) (step S7).

Next, according to the vehicle allocation order stored in the RAM, the vehicle allocation information 60 for the first taxi (see FIG. 2).
Reference) is created (step S8). This dispatch information 6
0 indicates the vehicle dispatch instruction I as in the format shown in FIG.
The call information 61 including D and the vehicle number “5”, the identification information 62 including the customer ID (for example, ID1), and the position information 63 including the latitude and longitude of the customer position CP shown in FIG. 9 are set.

This vehicle allocation information 60 is output from the main controller 10 to the wireless device 12 in the center 1 and is modulated therein to be the first taxi from the antenna 11 (taxi position M
-2) (step S9). As a result, if the approval signal can be received from the taxi (step S1
0), the dispatch instruction of the center 1 to the customer position CP ends. On the other hand, when the approval signal cannot be received from the taxi (step S10), the right to select a taxi is transferred to the next candidate taxi (step S11), and in this case, the second taxi (taxi position M The vehicle allocation information is transmitted to -1). In this way, the process is terminated or the dispatching instruction to the next candidate taxi is repeatedly executed depending on whether or not the dispatching instruction is accepted.

On the other hand, on the side of the taxi 2 instructed to dispatch,
The processing shown in FIG. 10 is executed. That is, when the vehicle allocation information is transmitted in step S9 in the flow of FIG. 4,
In step S31, the dispatch instruction ID 61 (see FIG. 2)
Is confirmed, the process proceeds to step S33. In addition,
