This minimizes customer waiting time and maximizes vehicle operating efficiency in the entire area.

In each boarding and alighting area of Embodiment 1, the number of vehicles always waiting is greater than or equal to the minimum number of vehicles (lower limit on the number of waiting vehicles) and less than the maximum number of vehicles on standby (the upper limit on the number of vehicles on standby). The entire system is controlled so that passengers can board the vehicle and travel to their destination without waiting.
That is, air traffic control is performed through the exchange of information between the control device 10, the facility auxiliary device 20, and the vehicle 30.
This will be explained in detail below.

The facility auxiliary device 20 takes in facility definition information 211 defined for each facility, that is, an apron and a landing area, and performs initial settings for each facility when the system is started.
Then, the facility receiving unit 21 receives the occupancy information 218 of waiting vehicles at the boarding and alighting area and the waiting status 219 of passengers at the boarding and alighting area.
While the system is in operation, the facility auxiliary device 20 dynamically collects information such as time information, the number of waiting vehicles, the number of arranged vehicles, the number of secured vehicles, the number of insufficient vehicles, the number of waiting passengers, the exhaustion time, the number of occupied vehicles, etc. at each facility, that is, the apron and the boarding area. The information of the facility status 212, which is data for managing information, is always updated to the latest value.
The updated facility status is notified from the facility transmitter 22 to the control device 10 through a notification 221 to the control device.
In addition, the facility transmitting unit 22 causes the HMI of the facility to display information required by the customer in response to a display instruction 220 to the HMI of the facility.

On the other hand, when the system is started, the vehicle 30 takes in vehicle definition information 311, which is data that defines static information such as vehicle type and initial arrangement, for each vehicle, and performs initial settings for each vehicle. Furthermore, a vehicle command 217 from the control device is received.
The vehicle 30 uses data that manages dynamic information such as time information, location information, current location, destination, locator information, command ID, route information, replenishable vehicle list, etc. of each vehicle while the system is in operation. A certain vehicle status 312 information is always updated to the latest value.
The updated vehicle status is notified from the vehicle transmitter 32 to the control device 10 through a notification 320 to the control device.

In the control device 10, the control receiving unit 11 receives a request from a customer from an application, a facility auxiliary device 20, or a vehicle 30. Further, the control transmission section 12 transmits a response to the request to the vehicle 30 or the passenger's mobile terminal.

Further, in the control device 10, as shown in FIG. 5, the actual vehicle requesting unit 40 updates the actual vehicle request data 214.
The available vehicle determination unit 80 takes in facility definition information 211, vehicle definition information 311, facility status 212 information, and vehicle status 312 information, selects a vehicle that can be used for dispatch from among the vehicles in the facility, and uses the vehicle. Possible vehicle data 280 is updated.
Here, the available vehicle determination unit 80 determines available vehicles based on the number of waiting customers.
Furthermore, the available vehicle determining unit 80 determines available vehicles based on the occupancy status of the waiting vehicles.

The highest priority facility selection unit 81 takes in facility definition information 211, vehicle definition information 311, facility status 212 information, and vehicle status 312 information, selects the highest priority facility with the highest replenishment priority, and selects the highest priority facility. Data 281 is updated. Note that the priority will be described later with reference to FIG.
Here, the highest priority facility selection unit 81 selects the highest priority facility based on the number of waiting customers.
Further, the highest priority facility selection unit 81 selects the highest priority facility based on the duration of time during which the number of waiting vehicles becomes zero.
Furthermore, the highest priority facility selection unit 81 selects the highest priority facility based on the number of vacant spots at the boarding and alighting areas.

The optimal vehicle selection unit 82 takes in the facility definition information 211, the vehicle definition information 311, the information on the facility status 212, and the information on the vehicle status 312, selects the optimal vehicle for allocating the vehicle to the boarding area, and generates the optimal vehicle data 282. Update.
Here, the optimal vehicle selection unit 82 selects the optimal vehicle based on the distance (mileage), that is, the positional relationship between the boarding area and the vehicle.
Furthermore, the optimal vehicle selection unit 82 selects the optimal vehicle based on the user's preferences.

The evacuation vehicle selection unit 83 takes in the facility definition information 211, vehicle definition information 311, information on the facility status 212, and information on the vehicle status 312, selects a vehicle to be evacuated from the boarding area, and updates the evacuation vehicle data 215.
Here, the evacuation vehicle selection unit 83 selects an evacuation vehicle based on the condition that no passenger is on board at the facility and no command has been given.
Further, the evacuation vehicle selection unit 83 selects an evacuation vehicle based on the condition that a vehicle will enter the warehouse in the near future (within n minutes) and the maximum number of vehicles to be secured will be exceeded.
In addition, the evacuation vehicle selection unit 83 selects evacuation vehicles based on the condition that the number of waiting vehicles exceeds the maximum number of vehicles to be secured, and the vehicles are moved to a facility that is within reachable distance and has a sufficient number of waiting vehicles. select.

Then, the vehicle command unit 70 takes in the actual vehicle request data 214, the available vehicle data 280, the highest priority facility data 281, the optimal vehicle data 282, and the evacuation vehicle data 215, and issues a vehicle command (vehicle allocation) to the vehicle 30. command).

Next, a specific example of the air traffic control according to the first embodiment will be explained using FIGS. 6 to 8.
In FIG. 6, there are four parked vehicles 530 on the parking lot 520. At this moment, there are two waiting vehicles 531 at the boarding and alighting area A521, three waiting vehicles 532 at the boarding and alighting area B522, and two waiting vehicles 533 at the boarding and alighting area C523.
Furthermore, at this moment, there are four waiting passengers 541 in the boarding/disembarking area A521, four waiting passengers 542 in the boarding/disembarking area B522, and four waiting passengers 543 in the boarding/disembarking area C523.

Then, the conditions indicating the state of the facility defined in FIG. 7 and the actions to be taken when this occurs are performed.
That is, in FIG. 7, the "waiting" state indicates a state in which the number of waiting passengers is greater than zero, and means that the number of waiting vehicles is insufficient. When such a condition occurs, the system determines that replenishment of vehicles from the tarmac or other landing area is necessary.
The "depleted" state means a state where the number of waiting vehicles is zero. When such a condition occurs, the system determines that replenishment of vehicles from the tarmac or other landing area is necessary.
The "shortage" state indicates a state in which the number of waiting vehicles is less than the minimum number of vehicles to be secured. When such a condition occurs, the system determines that replenishment of vehicles from the tarmac or other landing area is necessary.

In FIG. 7, the "surplus" state indicates a state where the number of waiting vehicles is greater than the minimum number of vehicles to be secured. When such a condition occurs, the system determines that movement of the vehicle to the parking lot or other boarding area is possible.
The "marginal" state indicates a state in which the number of waiting vehicles is less than the maximum number of vehicles that can be secured. When such a condition occurs, the system determines that a vehicle can be accepted from the tarmac or other pick-up area.
The "excessive" state indicates a state where the number of waiting vehicles is greater than the maximum number of vehicles that can be secured. When such a condition occurs, the system determines that it is necessary to evacuate the vehicle to an apron or other landing area.

The example of FIG. 8 will be explained in the state of FIG. 6.
In the initial state of FIG. 8, there are four parked vehicles 530 in the parking lot 520, two waiting vehicles 531 in the boarding area A521, three waiting vehicles 532 in the boarding area B522, and two waiting vehicles 533 in the boarding area C523. exist.

Each boarding and alighting area is always managed so that the minimum number of vehicles secured is two and the maximum number of vehicles secured is four, and replenishment and evacuation of vehicles are executed.

Next, it is assumed that a passenger drives an actual vehicle from the boarding/alighting area A521 to the boarding/alighting area B522 (flow a).
At this time, the number of waiting vehicles at the boarding area A521 decreases from two to one, which is less than the minimum number of waiting vehicles, resulting in a shortage. Therefore, a parking command for replenishment is issued from the parking lot 520, which has a sufficient number of waiting vehicles, to the boarding and alighting area A521, where there is a shortage of waiting vehicles. (Flow b)
At the same time, if things continue as they are, it can be predicted that the number of waiting vehicles at boarding area B522 will increase from three to four in the near future, reaching the maximum number of vehicles that can be secured.
Therefore, a vehicle allocation command for evacuation is issued from the boarding and alighting area B522 to the boarding and alighting area C523, which has sufficient number of waiting vehicles. (Flow c)

Next, a case where the vehicle allocation destination is changed during vehicle allocation will be described.
If the vehicle replenishment source or vehicle evacuation destination is far from the current location, it will take time to complete the dispatch, which may cause changes in the status of waiting passengers and waiting vehicles at each boarding and alighting facility.
In addition, an increase in the distance traveled by a vehicle results in energy loss, so vehicle allocation should always be made to reflect the latest situation and allow replenishment from a closer location or evacuation to a closer location. Dynamic optimization is required.

Therefore, in the first embodiment, the number of waiting vehicles at each boarding and alighting area is always appropriately managed according to the passenger demand at the time, and at the same time, the number of waiting vehicles is efficiently replenished and vehicles are dispatched for evacuation. The status of waiting passengers at each boarding and alighting area, the number of waiting vehicles, the current position, destination, and command status of each vehicle are grasped in real time, and the allocation of vehicles for replenishment and evacuation, as well as the destination of vehicles, are determined. It is now possible to dynamically change it even in the middle of the process.
This results in a transportation system that reduces completion time, reduces total energy consumption, eliminates congestion, minimizes passenger waiting time, and maximizes vehicle operating efficiency throughout the area. becomes possible.

Next, the priority of each facility in the transportation system according to the first embodiment will be explained using FIG. 9.
FIG. 9 explains the name, classification conditions, priority, and status update operation at the time of occurrence regarding the state (status) of each facility.
As mentioned above, at each boarding and alighting area, only the minimum number of vehicles to be secured and the maximum number of vehicles to be secured are maintained at all times, and passengers can board the vehicle without waiting and travel to their destination. The entire system is controlled to enable this. FIG. 9 shows the priority for this purpose.

In FIG. 9, the state of "(1a) Waiting/nearby" is a state in which the number of waiting customers is greater than zero, and the distance at which replenishment can be made is less than the proximity threshold indicating that the distance is nearby. Indicates a small condition. When such a situation occurs, the system prioritizes vehicle allocation in descending order of the number of waiting passengers. When the setting of the destination is completed, the number of waiting passengers is subtracted by 1.
The "(2a) depleted/nearby" state is a state in which the number of waiting vehicles is zero and the replenishable distance is smaller than the proximity threshold. When such a situation occurs, the system prioritizes vehicle allocation in descending order of depletion time. Once the destination setting is complete, the depletion time is reset to zero. (Replenish one unit and end)
The state of "(3a) shortage/nearby" indicates a state in which the number of waiting vehicles is less than the minimum number of vehicles to be secured, and the replenishable distance is smaller than the proximity threshold. When such a situation occurs, the system sets priority for dispatching vehicles in order of decreasing number of waiting vehicles. When the setting of the vehicle allocation destination is completed, the number of insufficient vehicles is subtracted by 1.

The state of "(1b) Waiting/Far" indicates a state where the number of waiting customers is greater than zero and the distance at which replenishment can be made is equal to or greater than the neighborhood threshold. When such a situation occurs, the system prioritizes vehicle allocation in descending order of the number of waiting passengers. When the setting of the destination is completed, the number of waiting passengers is subtracted by 1.
The "(2b) depleted/distant" state is a state where the number of waiting vehicles is zero and the replenishable distance is equal to or greater than the neighborhood threshold. When such a situation occurs, the system prioritizes vehicle allocation in descending order of depletion time. Once the destination setting is complete, the depletion time is reset to zero. (Replenish one unit and end)
The state of "(3b) Insufficient/Far" indicates a state in which the number of waiting vehicles is less than the minimum number of vehicles to be secured, and the replenishable distance is equal to or greater than the neighborhood threshold. When such a situation occurs, the system sets priority for dispatching vehicles in descending order of the number of vehicles in short supply. When the setting of the vehicle allocation destination is completed, the number of insufficient vehicles is subtracted by 1.

In the transportation system according to the first embodiment, vehicle allocation priorities are set in the order of (1a), (2a), (3a), (1b), (2b), and (3b) in FIG.

Next, a more detailed operation of the transportation system according to the first embodiment will be described using FIG. 10.
In FIG. 10(a), in the initial state, there are 4 waiting vehicles on the apron, 3 waiting vehicles at boarding and alighting area A521, 2 waiting vehicles at boarding and alighting area B522, and 2 waiting vehicles at boarding and alighting area C523. do.
Each boarding and alighting area is always managed so that the minimum number of vehicles secured is two and the maximum number of vehicles secured is four, and replenishment and evacuation of vehicles are executed.

Next, it is assumed that a user drives an actual vehicle from the boarding and alighting area C523 to the boarding and alighting area D (flow d). Note that the boarding/disembarking area D is a boarding/disembarking station other than the boarding area A521, the boarding/disembarking area B522, and the boarding/disembarking area C523, which are not shown in FIG.
At this time, the number of waiting vehicles at the boarding and alighting area C523 decreases from two to one, which is less than the minimum number of waiting vehicles, resulting in a shortage. Therefore, an instruction is issued from the parking lot 520, where there is a sufficient number of waiting vehicles, to the landing area C523, where there is a shortage of waiting vehicles, to allocate vehicles for replenishment. (Flow e)

Furthermore, it is assumed here that a user actually drives a vehicle from the boarding/alighting area A521 to the boarding/alighting area B522 (flow f).
At this time, boarding area A521 has room to accept vehicles from other facilities. In addition, since the number of waiting vehicles at boarding area B522 will increase from two to three in the near future, there is room to evacuate the vehicles to other facilities.

Therefore, as shown in FIG. 10(b), the dispatch of vehicles from the parking lot 520 to the boarding and alighting area C523 is interrupted, and the vehicle is newly instructed to dispatch the vehicle from the apron 520 to the boarding and alighting area A521 (flow g). At the same time, a vehicle allocation command (flow h) from the boarding/disembarking area B522 to the boarding/disembarking area C523 is issued. In this way, the vehicle allocation to the boarding and alighting area C523 is completed earlier than originally scheduled.
Further, the total distance traveled by the two vehicles after the change is smaller than the original distance traveled by one vehicle, and the total energy consumption is reduced.
If such optimization processing is carried out at each boarding and alighting area, the total waiting time for passengers can be shortened and vehicle running can be made more efficient.

Next, as another example, another operation of the transportation system according to the first embodiment will be described using FIG. 11.
In FIG. 11(a), in the initial state, there are 4 waiting vehicles in the parking lot 520, 4 waiting vehicles in the boarding and alighting area A521, 3 waiting vehicles in the boarding and alighting area B522, and 3 waiting vehicles in the boarding and alighting area C523. exist.
Each boarding and alighting area is always managed so that the minimum number of vehicles secured is two and the maximum number of vehicles secured is four, and replenishment and evacuation of vehicles are executed.

Next, assume that evacuation from landing area D to apron 520 occurs (flow j). Note that the boarding/disembarking area D is a boarding/disembarking station other than the boarding area A521, the platform B522, and the platform C523, which are not shown in the figure.
At this time, the number of vehicles waiting in the parking lot 520 is four, which has already reached the maximum number of vehicles that can be secured, so if this continues, the number of vehicles waiting will become excessive.
Therefore, an instruction (flow k) to allocate a vehicle for evacuation is issued from the parking lot 520 to the boarding and alighting area C523 where there is sufficient number of waiting vehicles.

Furthermore, it is assumed here that a user actually drives a vehicle from the boarding/alighting area A521 to the boarding/alighting area B522 (flow m).
At this time, the number of waiting vehicles at the boarding and alighting area A521 is reduced from four to three, creating room to accept vehicles from other facilities.

Therefore, as shown in FIG. 11(b), the vehicle allocation from the parking lot 520 to the boarding/alighting area C523 is interrupted, and the vehicle is newly instructed to allocate the vehicle from the parking lot 520 to the boarding/alighting area A521 (flow n). , the evacuation from the apron 520 will be completed sooner than originally planned.
Furthermore, the total distance traveled by the two vehicles after the change is smaller than the original distance traveled by one vehicle, and the total energy consumption is reduced.
If such optimization processing is carried out at each boarding and alighting area, the total waiting time for passengers can be shortened and vehicle running can be made more efficient.

According to the first embodiment, in situations where there is not enough room for the number of vehicles that can be parked in the parking lot, the number of waiting vehicles at each boarding and alighting area can be constantly and appropriately managed in real time according to the current passenger demand. , it is possible to realize a transportation system that does not cause congestion, minimizes passenger waiting time, and maximizes vehicle operating efficiency in the entire area.
In addition, while efficiently replenishing waiting vehicles at each boarding and alighting area and allocating vehicles for evacuation, we also provide information on the status of waiting passengers at each boarding and alighting area, the number of waiting cars, the current position of each vehicle, and the destination. Understand the command status in real time.
This makes it possible to dynamically change vehicle assignments and destinations for replenishment and evacuation even during the dispatch process, reducing time to completion and reducing total energy consumption. can.
In addition, it is possible to realize a transportation system that does not cause congestion, minimizes passenger waiting time, and maximizes vehicle operating efficiency in the entire area.
