Description

This application relates to a transportation system.

Patent Document 1 describes technology for providing a shared vehicle management device that calculates the demand for shared vehicles in a parking lot based on the usage history of users, calculates the supply of shared vehicles based on the number of shared vehicles parked in the parking lot, and sets the combination of parking lots that make up each zone to minimize the total difference between the demand and supply, thereby increasing convenience for users and reducing uneven distribution of shared vehicles.

JP 2019-145014 A (pages 4 to 7, Figure 1)

In Patent Document 1, under the conditions that the area managed by the system is wide, customers do not use their vehicles extremely frequently, there are many parking facilities where vehicles can be parked, and there is a surplus of vehicles that can be parked in the parking facilities, the system presents combinations of parking lots that make up each zone to customers so as to minimize the total difference between demand and supply, and allows them to select a parking lot, thereby increasing convenience for customers and reducing vehicle uneven distribution.
However, for example, in conditions where the area managed by the system is a narrow area such as a closed-loop single track, and usage is extremely high, such as for public transportation during morning and evening rush hours, and the facilities where vehicles can be parked are limited to parking lots adjacent to the track and each boarding and disembarking area, and there is no room for parking at each facility, simply reducing the uneven distribution of vehicles will lead to problems such as longer waiting times for passengers and reduced operating efficiency, making it impossible to meet passenger transportation demands.

This application discloses technology to solve the above-mentioned problems, and aims to provide a transportation system that shortens waiting times for vehicle users at boarding and disembarking points within a managed area and improves vehicle operating efficiency.

The transportation system disclosed in the present application is a transportation system comprising: a facility monitoring device that monitors facilities including boarding and alighting stops where vehicles wait and outputs a facility status indicating the state of the facility; and a control device that manages vehicle allocation using the facility status output by the facility monitoring device. The control device comprises : an available vehicle selection unit that selects vehicles within the facility that are available for allocation and creates available vehicle data; a highest priority boarding and alighting stop selection unit that selects the boarding and alighting stop with the highest priority based on a replenishment priority that is preset according to the state of the boarding and alighting stops and creates highest priority boarding and alighting stop data; a vehicle allocation selection unit that selects a vehicle to be allocated to the boarding and alighting stop selected by the highest priority boarding and alighting stop selection unit from the vehicles in the available vehicle data based on the driving distance to the boarding and alighting stop, and creates allocated vehicle data; and a vehicle command unit that generates commands to the relevant vehicle based on the highest priority boarding and alighting stop data and the allocated vehicle data. The priority is set high when the vehicle is within a driving distance from the boarding and alighting stop that is closer than a predetermined threshold value for driving distance .

The transportation system disclosed in this application can shorten waiting times for vehicle passengers at boarding and disembarking points within a managed area and increase vehicle operating efficiency.

FIG. 15 is a diagram showing vehicle statuses in the transportation system according to the first embodiment.
15, vehicle status 312 is data for managing the status of a vehicle, and includes a vehicle ID, current time, location information, current location, destination, current vehicle locator status, current operation ID (command ID), current routing status, and a list of vehicles that can be replenished.

Next, the operation will be described.
The transportation system of the first embodiment manages in real time the number of waiting passengers, waiting time, and number of waiting vehicles at each stop, which change from moment to moment.
In addition, the system manages the allocation of vehicles for replenishing and retracting vehicles so that the necessary number of waiting vehicles is always maintained at each stop, without excess or deficiency, according to the demand of passengers at each stop.
This will minimize waiting times for passengers and maximize vehicle utilization efficiency throughout the area.

At each boarding and disembarking area in embodiment 1, the entire system is controlled to maintain a state in which the number of vehicles waiting is always greater than or equal to the minimum number available (the lower limit of the number of waiting vehicles) and less than or equal to the maximum number available (the upper limit of the number of waiting vehicles), allowing passengers to board a vehicle without waiting and travel to their destination.
That is, traffic control is performed through the exchange of information between the control device 10, the facility-attached devices 20, and the vehicles 30.
This is explained in detail below.

When the system is started, the facility-attached device 20 retrieves facility definition information 211 that defines each facility, that is, each parking area and each landing area, and performs initial settings for each facility.
Then, the facility receiving unit 21 receives occupancy information 218 of vehicles waiting at the boarding/alighting area and waiting status 219 of passengers at the boarding/alighting area.
While the system is operating, the facility-related device 20 constantly updates the information in the facility status 212, which is data that manages dynamic information such as time information, number of waiting vehicles, number of arranged vehicles, number of secured vehicles, number of vehicles in short supply, number of waiting passengers, time of shortage, and number of occupied vehicles at each facility, i.e., parking lot and boarding/disembarking area, to the latest value.
The updated facility status is notified to the control device 10 from the facility transmitter 22 by a notification to the control device 221 .
Furthermore, the facility transmission unit 22 issues a display instruction 220 to the facility's HMI to cause the facility's HMI to display information required by the user.

On the other hand, when the system is started, the vehicle 30 retrieves vehicle definition information 311, which is data defining static information such as the vehicle type and initial location of each vehicle, and performs initial settings for each vehicle. Furthermore, the vehicle 30 receives vehicle commands 217 from the control device.
While the system is operating, vehicle 30 constantly updates the information in vehicle status 312, which is data that manages dynamic information for each vehicle, such as time information, location information, current location, destination, locator information, command ID, route information, and list of replenishable vehicles, to the latest value.
The updated vehicle status is notified to the control device 10 from the vehicle transmitter 32 by notification to control device 320 .

In the control device 10, the control receiving unit 11 receives requests from users from applications, facility-related devices 20, or vehicles 30. The control transmitting unit 12 transmits responses to the requests to the vehicles 30 or the users' mobile devices.

In addition, in the control device 10, the actual vehicle request unit 40 updates the actual vehicle request data 214 as shown in FIG.
The available vehicle determination unit 80 takes in the facility definition information 211, vehicle definition information 311, facility status information 212, and vehicle status information 312, selects vehicles within the facility that are available for dispatch, and updates the available vehicle data 280.
Here, the available vehicle determination unit 80 determines available vehicles based on the number of waiting passengers.
The available vehicle determination unit 80 also determines available vehicles based on the occupancy status of waiting vehicles.

The top-priority facility selection unit 81 receives the facility definition information 211, the vehicle definition information 311, the facility status information 212, and the vehicle status information 312, selects the top-priority facility with the highest priority for replenishment, and updates the top-priority facility data 281. Priority will be described later with reference to FIG. 9.
Here, the highest priority facility selection unit 81 selects the highest priority facility based on the number of waiting passengers.
The highest priority facility selection unit 81 also selects the highest priority facility based on the duration for which the number of waiting vehicles has been zero.
Furthermore, the highest priority facility selection unit 81 selects the highest priority facility based on the number of available spots at the boarding and disembarking area.

The optimum vehicle selection unit 82 takes in the facility definition information 211, vehicle definition information 311, facility status information 212, and vehicle status information 312, selects the optimum vehicle to be dispatched to the boarding/alighting point, and updates the optimum vehicle data 282.
Here, the optimum vehicle selection unit 82 selects the optimum vehicle based on the distance (travel distance), that is, the positional relationship between the boarding/alighting area and the vehicle.
Furthermore, the optimum vehicle selection unit 82 selects the optimum vehicle based on the user's preferences.

The evacuation vehicle selection unit 83 takes in the facility definition information 211 , vehicle definition information 311 , facility status information 212 , and vehicle status information 312 , selects a vehicle to be evacuated from the boarding and alighting area, and updates the evacuation vehicle data 215 .
Here, the evacuation vehicle selection unit 83 selects an evacuation vehicle based on the condition that the vehicle does not have passengers on board at the facility and no instructions have been given.
The evacuation vehicle selection unit 83 also selects vehicles to be evacuated based on the condition that vehicles will be brought into the warehouse in the near future (within n minutes) and the maximum number of vehicles to be secured will be exceeded.
The evacuation vehicle selection unit 83 also selects evacuation vehicles based on the condition that the vehicles are moved to a facility within a reachable distance that has a surplus of waiting vehicles by the number of waiting vehicles that exceeds the maximum number of vehicles that can be secured.

The vehicle command unit 70 then takes in the actual vehicle request data 214, available vehicle data 280, highest priority facility data 281, optimal vehicle data 282, and evacuation vehicle data 215, and generates a vehicle command (dispatch command) for the vehicle 30.

Next, a specific example of the control according to the first embodiment will be described with reference to FIGS.
6, there are four parked vehicles 530 at parking lot 520. At this moment, there are two waiting vehicles 531 at stop A 521, three waiting vehicles 532 at stop B 522, and two waiting vehicles 533 at stop C 523.
At this moment, there are four waiting passengers 541 at stop A521, four waiting passengers 542 at stop B522, and four waiting passengers 543 at stop C523.

Then, the conditions indicating the state of the facility defined in FIG. 7 and the actions to be taken when these conditions occur are performed.
7, the "waiting" state indicates that the number of waiting passengers is greater than zero, meaning that there are insufficient waiting vehicles. When this state occurs, the system determines that it is necessary to add vehicles from the parking lot or another boarding/deboarding area.
A "starved" situation means that the number of waiting vehicles is zero. When this situation occurs, the system determines that vehicles need to be refilled from the parking lot or other boarding/deboarding areas.
A "shortage" condition means that the number of waiting vehicles is less than the minimum number available. When this condition occurs, the system determines that additional vehicles are needed from the parking lot or another boarding/deboarding area.

In Figure 7, the "surplus" state indicates that the number of waiting vehicles is greater than the minimum number of vehicles available. When this state occurs, the system determines that the vehicles can be moved to an airport parking area or another boarding/deboarding area.
A "surplus" state means that the number of waiting vehicles is less than the maximum number of vehicles available. When this occurs, the system determines that a vehicle can be accepted from the parking lot or another boarding/deboarding area.
An "excess" situation means that the number of waiting vehicles is greater than the maximum number of vehicles available. When this situation occurs, the system determines that vehicles need to be evacuated to a parking area or other boarding/deboarding area.

The example of FIG. 8 will be described in the state of FIG.
In the initial state of FIG. 8, there are four parked vehicles 530 at parking lot 520, two waiting vehicles 531 at platform A 521, three waiting vehicles 532 at platform B 522, and two waiting vehicles 533 at platform C 523.

Each boarding and disembarking area is constantly managed to keep the minimum number of vehicles available within the range of two and the maximum number of vehicles available within the range of four, and vehicles are replenished and evacuated accordingly.

Next, it is assumed that a passenger takes a vehicle from platform A 521 to platform B 522 (flow a).
At this time, the number of waiting vehicles at stop A521 decreases from two to one, which is below the minimum number of waiting vehicles and causes a shortage. Therefore, a dispatch command is issued from parking lot 520, which has a surplus of waiting vehicles, to stop A521, which has a shortage of waiting vehicles (Flow b).
At the same time, if things continue as they are, it is predicted that the number of waiting vehicles at platform B522 will increase from three to four in the near future, reaching the maximum number of vehicles that can be secured.
Therefore, a dispatch command for evacuation is issued from platform B 522 to platform C 523, which has a sufficient number of waiting vehicles (Flow c).

Next, a case where the destination of a vehicle is changed during vehicle allocation will be described.
If the source of the vehicle replenishment or the destination where the vehicle is to be evacuated is far from the current location, it will take time to complete the vehicle dispatch, which may result in changes in the status of waiting passengers and waiting vehicles at each boarding and disembarking facility.
Furthermore, since an increase in vehicle travel distance results in energy loss, it is necessary to dynamically optimize vehicle dispatch allocation so that the latest situation is always reflected and vehicles can be replenished from closer locations or evacuated to closer locations.

Therefore, in embodiment 1, the number of waiting vehicles at each boarding/alighting station is always appropriately managed in accordance with passenger demand at the time, and vehicles are efficiently dispatched to replenish and evacuate waiting vehicles. At the same time, the waiting passenger situation at each boarding/alighting station, the number of waiting vehicles, the current position, destination, and command status of each vehicle are grasped in real time, and the allocation and destination of vehicles for replenishment and evacuation can be dynamically changed even while vehicles are being dispatched.
This will enable a transportation system that reduces completion time, reduces total energy consumption, eliminates congestion, minimizes waiting times for passengers, and maximizes vehicle utilization efficiency across the entire area.

Next, the priority of each facility in the transportation system according to the first embodiment will be described with reference to FIG.
FIG. 9 explains the name, classification conditions, priority, and status update operation when an event occurs for the status of each facility.
As mentioned above, the entire system is controlled to maintain a state in which there are always vehicles waiting at each stop that are equal to or greater than the minimum number of vehicles available and within the maximum number of vehicles available, so that passengers can board a vehicle without waiting and travel to their destination. Figure 9 shows the priority for this purpose.

In Figure 9, the "(1a) Waiting/Nearby" state indicates a state in which the number of waiting passengers is greater than zero and the distance available for refilling is less than the proximity threshold, which indicates a distance that is near. When this state occurs, the system sets dispatch priorities in descending order of the number of waiting passengers. Once the dispatch destination is set, the number of waiting passengers is decremented by one.
The "(2a) Depleted/Nearby" state indicates a state in which the number of waiting vehicles is zero and the distance available for replenishment is less than the near threshold. When this state occurs, the system assigns priority to vehicles in order of the longest depletion time. Once the destination for the vehicle has been assigned, the depletion time is reset to zero. (One vehicle is replenished and the process is completed.)
The "(3a) Shortage/Proximity" state indicates a state in which the number of waiting vehicles is less than the minimum number of vehicles available and the distance available for replenishment is less than the proximity threshold. When this state occurs, the system assigns priority to waiting vehicles in descending order of the number of vehicles in short supply. Once the assignment destination is set, the number of vehicles in short supply is decremented by one.

The "(1b) Waiting/Far" state indicates a state in which the number of waiting passengers is greater than zero and the distance available for refilling is equal to or greater than the proximity threshold. When this state occurs, the system sets the dispatch priority in descending order of the number of waiting passengers. Once the dispatch destination is set, the number of waiting passengers is decremented by one.
The "(2b) Depleted/distant" state refers to a state in which the number of waiting vehicles is zero and the distance available for replenishment is equal to or greater than the proximity threshold. When this state occurs, the system assigns priority to vehicles in order of the longest depletion time. Once the destination for the vehicle has been assigned, the depletion time is reset to zero. (One vehicle is replenished and the process is completed.)
The "(3b) Shortage/Far Away" state indicates a state in which the number of waiting vehicles is less than the minimum number of vehicles available and the distance available for replenishment is equal to or greater than the proximity threshold. When this state occurs, the system assigns priority to vehicles in descending order of the number of waiting vehicles that are in short supply. Once the assignment destination is set, the number of vehicles that are in short supply is decremented by one.

In the transportation system according to embodiment 1, dispatch priorities are set in the order of (1a), (2a), (3a), (1b), (2b), and (3b) in Figure 9.

Next, the operation of the transportation system according to the first embodiment will be described in more detail with reference to FIG.
In FIG. 10( a ), in the initial state, there are four waiting vehicles at the parking lot, three waiting vehicles at stop A 521 , two waiting vehicles at stop B 522 , and two waiting vehicles at stop C 523 .
At each stop, the minimum number of vehicles available is always managed to stay within the range of two and the maximum number of vehicles available is four, and vehicle replenishment and evacuation are carried out.

Next, assume that a user takes a vehicle from platform C523 to platform D (flow d). Platform D is a platform other than platform A521, platform B522, and platform C523, which is not shown in FIG. 10 .
At this time, the number of waiting vehicles at stop C523 decreases from two to one, which is below the minimum number of waiting vehicles and causes a shortage. Therefore, an instruction is issued from parking lot 520, which has a surplus of waiting vehicles, to stop C523, which has a shortage of waiting vehicles, to dispatch vehicles to replenish the waiting vehicles (Flow e).

Furthermore, it is assumed here that a user has taken a vehicle from platform A521 to platform B522 (flow f).
At this time, stop A 521 has room to accept vehicles from other facilities. Also, at stop B 522, the number of waiting vehicles will increase from two to three in the near future, so there is room to evacuate vehicles to other facilities.

10(b), the dispatch of the vehicle from the parking lot 520 to the boarding/alighting area C 523 is suspended, and a new command (flow g) is issued to the vehicle to dispatch the vehicle from the parking lot 520 to the boarding/alighting area A 521, and at the same time, a command (flow h) is issued to dispatch the vehicle from the boarding/alighting area B 522 to the boarding/alighting area C 523. In this way, the dispatch of the vehicle to the boarding/alighting area C 523 is completed earlier than originally planned.
Furthermore, the total distance traveled by the two vehicles after the change is smaller than the distance traveled by the original single vehicle, resulting in a reduction in the total amount of energy consumption.
If this type of optimization processing is carried out at each stop, it will be possible to reduce passenger waiting times overall and improve the efficiency of vehicle operation.

Next, as another example, another operation of the transportation system according to the first embodiment will be described with reference to FIG.
In FIG. 11( a ), in the initial state, there are four waiting vehicles at parking lot 520 , four waiting vehicles at boarding/alighting point A 521 , three waiting vehicles at boarding/alighting point B 522 , and three waiting vehicles at boarding/alighting point C 523 .
At each stop, the minimum number of vehicles available is always managed to stay within the range of two and the maximum number of vehicles available is four, and vehicle replenishment and evacuation are carried out.

Next, it is assumed that evacuation from platform D to parking area 520 occurs (flow j). Platform D is a platform other than platform A 521, platform B 522, and platform C 523, which are not shown in the figure.
At this time, the number of waiting vehicles in the parking lot 520 is four, which is already the maximum number of vehicles that can be reserved, so if this continues, there will be an excess of waiting vehicles.
Therefore, an instruction (flow k) is issued from the parking lot 520 to dispatch vehicles to a boarding/disembarking area C523 where there are sufficient waiting vehicles.

Furthermore, it is assumed here that a user has taken a vehicle from platform A521 to platform B522 (flow m).
At this time, the number of waiting vehicles at platform A521 decreases from four to three, creating room to accept vehicles from other facilities.

Therefore, as shown in Figure 11 (b), if the dispatch of the vehicle from parking lot 520 to boarding/disembarking point C523 is interrupted and a new instruction (flow n) is issued to the vehicle to dispatch from parking lot 520 to boarding/disembarking point A521, the evacuation from parking lot 520 will be completed earlier than originally planned.
Furthermore, the total distance traveled by the two vehicles after the change is smaller than the distance traveled by the original single vehicle, resulting in a reduction in the total amount of energy consumption.
If this type of optimization processing is carried out at each stop, it will be possible to reduce passenger waiting times overall and improve the efficiency of vehicle operation.

According to embodiment 1, in situations where there is not enough space in the parking lot to accommodate all the vehicles, the number of waiting vehicles at each boarding and disembarking area can be constantly and appropriately managed in real time in accordance with current passenger demand, thereby realizing a transportation system that does not cause congestion, minimizes waiting times for passengers, and maximizes vehicle operating efficiency throughout the area.
In addition, the system efficiently dispatches vehicles to replenish and evacuate waiting vehicles at each stop, and at the same time, grasps the status of waiting passengers at each stop, the number of waiting vehicles, the current position of each vehicle, its destination, and the command status in real time.
This allows the allocation and destination of vehicles for replenishment and evacuation to be dynamically changed even while the vehicles are being dispatched, reducing the time required to complete the task and reducing total energy consumption.
It will also be possible to create a transportation system that does not cause congestion, minimizes waiting times for passengers, and maximizes vehicle operating efficiency throughout the area.

The traffic system control device 10, facility attached device 20, and vehicle 30 each comprise a processor 1000 and a storage device 1001, as shown in FIG. 16, which is an example of hardware. The storage device is not shown, but includes a volatile storage device such as random access memory and a non-volatile auxiliary storage device such as flash memory. A hard disk auxiliary storage device may also be used instead of flash memory. The processor 1000 executes a program input from the storage device 1001. In this case, the program is input to the processor 1000 from the auxiliary storage device via the volatile storage device. The processor 1000 may output data such as calculation results to the volatile storage device of the storage device 1001, or may store the data in the auxiliary storage device via the volatile storage device.
