  Next, with reference to FIG. 3, processing in the patrol vehicle dispatch support system 1 in the embodiment will be described. FIG. 3 is a flowchart showing processing in the patrol car dispatch support system 1 in the embodiment.

  First, the information acquisition unit 111 acquires various information from the vehicle sensor 2, the monitoring camera 3, the general vehicle 4, and the patrol car PC, and stores the acquired information in the acquired information storage unit 122 (step S1).

  Next, based on the information stored in the acquired information storage unit 122, the traffic situation calculation unit 112 calculates a traffic situation including the degree of traffic congestion of the vehicle on the expressway, and stores it in the traffic situation storage unit 123 ( Step S2).

  Next, on the basis of the information stored in the acquired information storage unit 122, the traveling vehicle situation calculation unit 113 calculates the traveling vehicle situation including the current location for the plurality of traveling vehicle PCs on the expressway, and the traveling vehicle situation storage It stores in the unit 124 (step S3).

  Next, the processing unit 11 determines whether or not an event has occurred (Step S4). If the determination is Yes, the process proceeds to Step S5, and if the determination is No, the process returns to Step S1.

  In step S5, the event registration unit 114 receives an event registration operation based on the input of information using the input unit 13 by the operator, and stores the contents in the event storage unit 125.

  Next, the vehicle allocation candidate information creation unit 115 performs the processes of steps S7 to S9 for all the traveling vehicle PCs (steps S6 to S10).

  In step S7, the dispatch candidate information creation unit 115 determines whether or not work is underway based on the traveling vehicle status stored in the traveling vehicle status storage unit 124 for the traveling vehicle PC to be processed, and in the case of Yes Steps S8 and S9 are skipped (excluded from the vehicle allocation candidate), and in the case of No, the process proceeds to step S8.

  In step S8, the dispatch candidate information creation unit 115 determines the traveling vehicle PC to be processed based on the road information stored in the road information storage unit 121 and the traveling vehicle condition calculated by the traveling vehicle condition calculation unit 113. , The travel route to the event occurrence location is calculated.

  In the example of FIG. 1, the traveling route of the traveling vehicle PC1 is from the current location to the interchange IC1, the turnaround at the interchange IC1, the turnaround from the interchange IC1 to the interchange IC2, the turnaround at the interchange IC2, and the turn from the interchange IC2 to the event occurrence location And.

  In addition, the traveling route of the patrol car PC2 is from the present location to the interchange IC2, the turn back at the interchange IC2, and the interchange IC2 to the event occurrence location.

  In addition, the traveling route of the patrol car PC3 is from the present location to the interchange IC3, the turn back at the interchange IC3, and the interchange IC3 to the event occurrence location.

  In addition, the traveling route of the patrol car PC4 is from the current location to the event occurrence location.

  Next, in step S9, the dispatch candidate information creation unit 115 calculates the travel route calculated for the traveling vehicle PC to be processed, and the traffic condition (average speed of each point in the travel route) calculated by the traffic condition calculation unit 112. Based on the above, etc., the required time to the event occurrence location is calculated, and dispatch candidate information including the required time is created.

  When the processes of steps S6 to S10 are completed, the display control unit 116 displays the vehicle allocation candidate information created by the vehicle allocation candidate information creation unit 115 on the display unit 14 in step S11.

  Here, FIG. 4 is a diagram showing a display example of the vehicle allocation candidate information in the embodiment. As shown in FIG. 4, in the display unit 14, as vehicle allocation candidate information, from the left, vehicle allocation candidate order, traveling vehicle ID (Identifier), current location, travel route to event occurrence location, required time to event occurrence location Each item of information is displayed. The travel route to the event occurrence location is abbreviated, but the contents are as described above. Moreover, when displaying allocation candidate information, you may also display the information of a route map as shown in FIG. 1 collectively.

  Referring also to FIG. 1, the patrol car PC1 is located on the same road RT2i as the event occurrence location, and is the closest to the event occurrence location in straight distance among all the patrol vehicles PC. However, the traveling direction and the direction to the event occurrence location are opposite, and the traveling vehicle PC1 must go through the above-mentioned travel route to reach the event occurrence location, and the required time is about 30 minutes. .

  The patrol car PC2 is located on the road RT2o, and among all the patrol cars PC, the length of the traveling route is the shortest. However, since there is a traffic jam A from the present location to the interchange IC2, the traveling vehicle PC2 has a traveling time of about 15 minutes, which is longer than the traveling vehicle PC1.

  The patrol car PC3 is located on the road RT3o, and there is no congestion in the travel route to the event occurrence location. However, since traveling vehicle PC3 has a traveling route longer than traveling vehicle PC4, the traveling time is approximately 10 minutes longer than traveling vehicle PC4.

  The patrol car PC4 is located on the road RT4i, and among all the patrol cars PC, the straight distance is the farthest to the event occurrence location. However, since there is no congestion in the traveling route to the event occurrence location, and there is no return traveling at the interchange IC, the traveling vehicle PC 4 has a shortest travel time of approximately 6 minutes.

  In the vehicle allocation candidate information shown in FIG. 4, only a few upper traveling vehicle PCs may be displayed, and all the traveling vehicle PCs other than those in work may be displayed. Also, all patrol car PCs may be displayed, including those under work. If the patrol car PC in operation is also displayed, for example, if the degree of urgency of the event is high, even if it is the patrol car in operation, take action to interrupt the operation and issue a dispatch instruction. You can also.

  Returning to FIG. 3, after step S11, in step S12, the dispatch instruction unit 117 instructs the designated traveling vehicle PC to dispatch (output) based on the input of the information using the input unit 13 by the operator. . For example, when the operator selects one traveling vehicle PC using the input unit 13 on the screen of the vehicle allocation candidate information displayed on the display unit 14 shown in FIG. 4, the vehicle allocation instruction unit 117 selects the selected traveling vehicle PC. Direct the dispatch (outgoing) to After step S12, the process returns to step S1.

  In this manner, according to the patrol vehicle distribution support system 1 of the embodiment, it is possible to support the distribution of a patrol vehicle estimated to be able to reach the event occurrence location quickly on the expressway (port with entrance restriction). it can. That is, instead of selecting the vehicle closest to the destination as in the conventional technology related to ordinary roads, it is possible to reach the event occurrence location taking into consideration the characteristics of the expressway where the exit, entrance and returnable locations are limited. The support can be realized by calculating the required time.

  Further, by excluding the traveling vehicle PC in operation from the dispatching candidate, it is possible to avoid the situation in which the traveling vehicle PC in operation with high possibility of being unable to cope with it immediately becomes the dispatching candidate.

  In addition, for each of a plurality of traveling vehicle PCs, first, the travel route to the event occurrence location is calculated, and thereafter, the required time to the event occurrence location is calculated based on the travel route and the traffic condition. Operations can be easily realized.

  In addition, the required time to the event occurrence location can be calculated using the information on the route and time required for the return trip, which varies depending on the possible return locations, so that the required time can be calculated with higher accuracy.

  As mentioned above, although embodiment of this invention was described, the said embodiment is an example to the last, and limiting the scope of invention is not intended. The above embodiments can be implemented in various forms, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. The embodiments described above are included in the scope and the gist of the invention, and are included in the invention described in the claims and the equivalents thereof.

  For example, the target road is not limited to the expressway, and it may be paid or free if it is an entrance-restricted road in which the exit and entrance of the vehicle are limited.

  In addition, the patrol car PC in operation is excluded from the dispatch candidates, but is not limited thereto. For example, a traveling vehicle PC that is near the end of work even if it is a traveling vehicle PC in operation may not be excluded from the dispatch candidates.

  Further, the place where the vehicle can travel back is not limited to the interchange IC, and may be another place. In addition, there may be an interchange IC that can not be turned around. In that case, it is good also as what carries out return driving | running | working by leaving and entering an interchange IC once again. In those cases, those information may be stored in the road information storage unit 121.
