Description

  The present invention relates to a vehicle operation system that creates an operation plan based on a demand from a user and operates the vehicle along the created operation plan.

In recent years, a vehicle operation system such as a demand bus system that prepares an operation plan in response to a demand including a boarding position, a boarding time, and a getting-off position desired by a user, and operates a vehicle such as a bus according to the created operation plan. Has attracted attention (see Patent Document 1). In such a vehicle operation system, based on the received demand, an operation plan is created in consideration of the user's conditions throughout the service area, such as boarding waiting time, detour time, or total vehicle travel time, or the travel conditions of the operating vehicle. Can be done.

  According to such a vehicle operation system, the user can receive a service that can be freely accessed from anywhere without any connection within the service area. For this reason, it is possible to provide services with significantly higher cost performance than the route bus system.

JP 2003-173497 A

  However, since the above conventional vehicle operation system can provide a service with a high degree of freedom, the route bus such as a long distance or an enclave tends to be used more frequently in areas where the operation service provision conditions are poor. For this reason, when the vehicle is occupied for use in an area where the conditions are bad, the overall efficiency tends to decrease.

  With such route buses, use of areas where the conditions for providing service services are poor may reduce the operating efficiency of bus vehicles, so it is possible to increase the fare and bias long-distance use etc. However, it is difficult to set a clear distance fare because it is not a route system. In the bus service, it was difficult to raise the price because the fare was expensive.

  By the way, the tendency for the overall efficiency in the conventional vehicle operation system to decrease is due to the fact that an operation plan is created based on exactly the same criteria for a bad condition and a good condition. Therefore, it is conceivable to differentiate the service level of each zone according to the required time, waiting time or detour time, which is a service index of a conventional vehicle operation system.

  However, with this method, when there is a demand in the immediate vicinity of a demand that has already been reserved or when there is a demand request on almost the same route, it is not necessary to reduce the service level and make a reservation with a longer waiting time. Operational efficiency will be lost. Conversely, when multiple demands with poor service levels are concentrated in the same zone, the conventional service index method aims to improve the overall service. It will be concentrated and allocated to those demands, and it will not be possible to prevent unbalanced vehicles.

  The present invention has been made in view of the above circumstances, and easily creates an operation plan that can appropriately ensure a service that takes into account the characteristics of the area within the service area without reducing the operational efficiency of the vehicle. An object of the present invention is to provide a new vehicle operation system capable of providing a vehicle operation service.

The vehicle operation system according to the present invention includes a zone allocation level storage means for storing a zone allocation level that is a allocation level for each of a plurality of zones set in the operation service area of at least one vehicle; In response to new use request information of the vehicle including the desired boarding time, the current operation plan is updated in consideration of the zone allocation level stored in the zone allocation level storage means, and the optimized new operation An operation plan creation means for creating a plan; and an operation control means for extracting a boarding / alighting point in order of operation time for each vehicle based on the new operation plan and transmitting it to the in-vehicle device of the corresponding vehicle , zone dispatch level include metrics in the zone stay rate of the vehicle to stay on trip plan to the appropriate zone, the vehicle operation system, characterized in that It is.

In this vehicle operation system, the operation plan creation means is stored in the zone dispatch level storage means in response to new information on demand (demand) of vehicles such as buses including the boarding / exit points, the number of passengers and the desired ride time. The current operation plan is updated in consideration of the zone allocation level. As a result, the operation plan creation means creates a new operation plan that is optimized in consideration of the characteristics of each zone in the service area while preventing the unbalanced vehicles.
The zone allocation level includes an indicator of the stay rate in the zone of a vehicle staying in the corresponding zone in the operation plan.

  In this way, when a new operation plan is created, the operation control means extracts the boarding / exiting points in order of operation time for each vehicle based on the new operation plan, and transmits it to the in-vehicle device of the corresponding vehicle. Each vehicle is operated based on the information of the boarding / exiting points in the order of the operation time transmitted in this way.

  Therefore, according to the vehicle operation system of the present invention, it is possible to easily create an operation plan that can appropriately guarantee a service that takes into account the characteristics of the area within the service area without reducing the operation efficiency of the vehicle. Service can be provided.

In the vehicle operation system of the present invention, when the number of the vehicles is plural, the zone allocation level includes the sum of the stay rates in the zones of the plurality of vehicles staying in the corresponding zone in the operation plan. An indicator can be included.

  In the vehicle operation system according to the present invention, the zone allocation level may include an index value of a visit time interval of a vehicle that visits the corresponding zone in the operation plan.

  Further, in the vehicle operation system of the present invention, the operation plan creation means performs a comprehensive evaluation that further considers the normal service level index including the waiting time and the detour time in addition to the zone allocation level index value. Thus, the new operation plan can be created.

  As described above, according to the vehicle operation system of the present invention, an efficient and rational operation plan can be created even when a region having good conditions and a region having bad conditions for vehicle operation are mixed. The vehicle operation service can be provided.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the drawings, the same or equivalent elements are denoted by the same reference numerals, and redundant description is omitted.

Here, as the vehicle allocation level information 210, the upper limit U _k (k = ZA, ZB, ZC) of the zone vehicle allocation level index, which is the vehicle allocation level index for each of the zones ZA, ZB, ZC, is stored. Such a zone allocation level index is determined in advance based on results, simulation, experience, and the like.

  In the present embodiment, as the zone allocation level indicator, the vehicle stay rate in each zone, that is, the upper limit of the average number of vehicles allocated for each predetermined time interval (for example, every 5 minutes) in each zone (hereinafter, “ The upper limit dispatch index is called. An example of the contents of the vehicle allocation level information 210 set in this way is shown in FIG.

In the reservation list 220, demands that are reserved in the current operation plan are registered. In the operation plan information 230 , the current operation plan is registered.

  Returning to FIG. 3, when receiving the contents of the new demand, the operation plan creation unit 115 creates the new operation plan candidate. When a new operation plan is determined, the operation plan creation unit 115 adds the content of the new demand to the reservation list 220 and changes the content of the operation plan information 230 to the determined new operation plan. Update. Details of the processing in the operation plan creation unit 115 will be described later.

In the present embodiment, for the bus vehicle 150 _j (j = 1 to 4), the route, the schedule, and the assigned area are not set in advance, and about 200 bus stops are set as a whole. And the operation plan preparation part 115 performs the combination of free boarding / alighting and a vehicle allocation calculation according to a demand, selects an optimal solution, and produces an operation plan.

  The display device 153 includes a liquid crystal display panel and the like. The display device 153 performs image display according to the display image data from the control device 152.

[Operation]
Next, the operation of the demand bus system 100 configured as described above will be described mainly focusing on demand processing.

  As a premise, an operation plan corresponding to at least one demand received so far (hereinafter referred to as “current operation plan”) is created and registered as operation plan information 230 in the storage unit 114 of the management center 110 And In addition, it is assumed that the contents of the demand that has been reserved in the current operation plan are registered in the reservation list 220 in the storage unit 114.

  In this demand process, as shown in FIG. 5, it is first determined in step S11 whether a new demand has been received from the user. If the result of this determination is negative (step S11: N), the process of step S11 is repeated.

  On the other hand, when the operator receives a new demand from the telephone device 111, the result of determination in step S11 becomes affirmative (step S11: Y), and the process proceeds to step S12. In step S12, a new demand input process is performed. In such a new demand input process, the operator operates the input device 112 while confirming the display on the display device 113, and inputs the contents of the new demand to the operation plan creation unit 115. The contents of such a new demand include the name of the bus stop to get on and off, the number of passengers and the desired time of boarding.

  Next, in step S13, the operation plan creation unit 115 performs a process for creating a new operation plan corresponding to the contents of the new demand. In this process, as shown in FIG. 6, first, a new operation plan candidate is created in step S21.

  In creating this new operation plan candidate, as shown in FIG. 7, first, in step S31, the operation plan creation unit 115 newly sets the demand content registered in the reservation list 220 and the new demand content. Create a new combination of reservations that is a unique combination. Subsequently, in step S32, the zone allocation level index is calculated for the new reservation combination.

In the calculation process of the zone allocation level index, first, the operation plan creation unit 115 traces the movement of each bus vehicle 150 _j (j = 1 to 4) with respect to a new reservation combination in time, A zone stay list is created from the transition. In addition, the zone transition time (tt) is the road before the stride when adding zone information belonging to the node of the road based on the temporary operation plan created from the new reservation combination and straddling two zones. Using the departure time (t1) of the current node and the arrival time (t2) of the road node after straddling, it is calculated by the following equation (1).
tt = t1 + (t2−t1) × (L1 / L2) (1)
Here, the value L1 is the distance from the node before straddling to the zone boundary, and the value L2 is the distance between nodes before and after straddling.

  In other words, in the present embodiment, the zone transition time (tt) is calculated by using the departure time (t1) of the node of the road before straddling and the arrival time (t2) of the node of the road after straddling. It is required to be prorated by distance. In the present embodiment, the distance from the road node to the zone boundary is obtained by calculating the intersection between the nodes by setting the zone boundary as a latitude / longitude value or a linear expression thereof.

Thus the bus fleet 0.99 _j another zone transition list obtained, trip plan creating unit 115 creates a stay list for recording the respective input and time of bus fleet 0.99 _j of each zone.

Subsequently, from the entry / exit times of the bus vehicles 150 _j for each zone obtained as described above, the operation plan creation unit 115 makes the vehicle stay rate for each zone, for example, for each fixed time interval (T0) such as a 5-minute interval. P _k (k = ZA, ZB, ZC) is calculated by the following equation (2) as the stay time (TV _kj ) of the bus vehicle 150 _{j in} the zone in the target time zone.
P _k = (TV _k1 + TV _k2 + TV _k3 + TV _k4 ) / T0 (2)

  For example, when one bus vehicle stays in the zone ZA during the corresponding period and the other one stays for half of the corresponding period, the vehicle stay rate in the zone ZA in that time zone is 1 .5.

When the vehicle stay rate P _k in each target time zone is thus calculated, in step S33, the operation plan creation unit 115 determines whether or not the vehicle stay rate P _k may exceed the upper limit index value U _k. Thus, it is determined whether or not the first evaluation regarding the zone allocation level index is passed. If the result of this determination is negative (step S33: N), the process proceeds to step 37.

  If the result of the determination in step S33 is affirmative (step S33: Y), the process proceeds to step S34. In step S34, the operation plan creation unit 115 calculates the service index and the operation index of the temporary operation plan created above. Here, the service index includes waiting time, detour time, and the like, and the operation index includes total travel time and the like. That is, in step S34, an index used in creating an operation plan in a conventional demand bus system is calculated.

  When the service index and the operation index of the temporary operation plan are calculated in this way, in step S35, the operation plan creation unit 115 has an extremely bad value in the calculated index as compared with the case of the current operation plan. By determining whether or not it is included, it is determined whether or not the first evaluation regarding the service index and the operation index is passed. If the result of this determination is negative (step S35: N), the process proceeds to step 37.

  If the result of the determination in step S35 is affirmative (step S35: Y), the process proceeds to step S36. In step S36, the temporary operation plan is added as a new operation plan candidate.

  Next, in step S37, the operation plan creation unit 115 performs the primary regarding the zone allocation level index, the service index, and the operation index for all combinations of the demand contents registered in the reservation list 220 and the new demand contents. Determine whether the evaluation is complete. If the result of this determination is negative (step S37: N), the process returns to step S31. Thereafter, the processes in steps S31 to S37 are repeated until the result of the determination in step S37 becomes affirmative.

  When the first evaluation of all the combinations is completed, the result of determination in step S37 is affirmative (step S37: Y), and the process proceeds to step S38. In step S38, the operation plan creation unit 115 ranks new operation plan candidates that have passed the first evaluation regarding the zone allocation level index, the service index, and the operation index. This ranking is performed by comprehensively considering the zone allocation level index, the service index, and the operation index. That is, the overall rank is increased as the zone allocation level index is lower, the service index value is smaller, and the operation index value is smaller.

  Thus, when the ranking of the new operation plan candidate is finished, the process of step S21 is finished. Then, the process proceeds to step S22 in FIG.

  In step S <b> 22, the user is notified of reservation details such as the available boarding time corresponding to the new demand based on the first candidate with the highest rank among the ranked new operation plan candidates. In the notification process, first, the operation plan creation unit 115 causes the display device 113 to display reservation contents such as a boarding time corresponding to a new demand based on the first candidate. The operator who sees the displayed content notifies the user who is talking using the telephone device 111 of the content.

  Next, in step S23, first, the operation plan creation unit 115 determines whether or not the user's consent has been obtained. Here, the operation plan creation unit 115 makes an affirmative determination when the input device 112 reports that the operator has performed an operation input indicating that the operator has obtained an understanding. On the other hand, the operation plan creation unit 115 makes a negative determination when the input device 112 reports that the operator has made an operation input to the input device 112 indicating that the operator did not understand.

  If the result of the determination in step S23 is affirmative (step S23: Y), a new operation plan candidate that is a candidate at that time is determined as a new operation tuberculosis, and the process in step S13 ends. To do. Then, the process proceeds to step S14 in FIG.

  Returning to FIG. 6, when the result of the determination in step S23 is negative (step S23: N), the process proceeds to step S24. In step S24, the operation plan creation unit 115 determines whether there is a next candidate as a new operation plan candidate.

  If the result of the determination in step S24 is affirmative (step S24: Y), the process proceeds to step S25. In this step S25, the user is notified of reservation contents such as boarding time corresponding to a new demand based on the next candidate. In the notification process, first, the operation plan creation unit 115 causes the display device 113 to display reservation contents such as a boarding time corresponding to a new demand based on the first candidate. The operator who sees the displayed content notifies the user who is talking using the telephone device 111 of the content.

  Thereafter, the process returns to step S23. And the process of said step S23-S25 is repeated until the result of determination in step S23 becomes affirmative or the result of determination in step S24 becomes negative.

  If the result of the determination in step S24 is negative (step S24: N), the process proceeds to step S26. In this step S26, the user is notified that reservation for bus use related to a new demand is not possible. When making such notification, first, the operation plan creation unit 115 displays on the display device 113 that the bus use reservation corresponding to the new demand is impossible. The operator who sees the display contents uses the telephone device 111 to notify the user who is in a call.

  When the process of step S26 ends, the process of step S13 ends. Then, the process proceeds to step S14 in FIG.

  In step S14, the operation plan creation unit 115 determines whether a new operation plan has been determined. If the result of this determination is negative (step S14: N), the process returns to step S11.

  On the other hand, when the result of the determination in step S14 is affirmative (step S14: Y), the process proceeds to step S15. In step S15, the operation plan creation unit 115 adds the content of the new demand to the reservation list 220, and updates the content of the operation plan information 230 to the determined new operation plan. At the time of this update, the operation plan creation unit 115 further sets an update flag in the operation plan information 230 to ON. Thereafter, the process returns to step S11.

  Thereafter, the process of steps S11 to S15 is repeated, so that a new operation plan creation process corresponding to the new demand is performed.

In parallel with the above-described process for creating a new operation plan by the operation plan creation unit 115, the operation control unit 116 creates the operation instruction RTD _j (j = 1 to 4) and notifies the bus vehicle 150 _j . Is done. In the process of creating and notifying the operation instruction RTD _j , as shown in FIG. 8, first, in step S41, the operation plan creating unit 115 determines whether or not a predetermined time has elapsed.

  If the result of the determination in step S41 is negative (step S41: N), the process returns to step S41. And the process of step S41 is repeated until the result of determination in step S41 becomes affirmative.

  When the predetermined time has elapsed and the result of the determination in step S41 is affirmative (step S41: Y), the process proceeds to step S42. In step S42, the operation control unit 116 determines whether or not the operation plan information 230 has been updated since the previous reference by determining whether or not the update flag in the operation plan information 230 is ON. . If the result of this determination is negative (step S42: N), the process returns to step S41. And the process of said step S41, S42 is repeated until the result of determination in step S42 becomes affirmative.

  If the operation plan information 230 is updated by the operation plan creation unit 115 and the result of determination in step S42 is affirmative (step S42: Y), the process proceeds to step S43. In step S43, the operation control unit 116 acquires the operation plan registered in the operation plan information 230. And the update flag in the operation plan information 230 is set to ON.

Next, in step S44, the operation control unit 116 creates an operation instruction RTD _j to be notified to each of the bus vehicles 150 _j (j = 1 to 4) based on the acquired operation plan. Subsequently, in step S45, the operation control unit 116 sends the generated operation instruction RTD _j to the bus vehicle 150 _j via the communication unit 117.

  Thereafter, the process returns to step S41. And the operation control part 116 repeats the process of said step S41-S45.

When the operation instruction RTD _j issued from the management center 110 is received as described above, the content is displayed on the display device 153 in the bus vehicle 150 _j . Then, the contents of the operation instruction RTD _j are presented to the driver on the bus vehicle 150 _j .

  As described above, in the present embodiment, a zone allocation level reference index is determined for each zone in the service area SVR, and an operation plan is created in consideration of the zone allocation level reference index. Therefore, according to the present embodiment, an efficient and rational operation plan is created and a bus operation service is provided even when a region having good conditions and a region having bad conditions for bus operation are mixed. be able to.

That is, according to the present embodiment, the vehicle operation is excessively used for special use such as long-distance use, and the service is unevenly distributed, thereby preventing a tendency that it is difficult to perform proper vehicle operation for the entire district. However, it is possible to optimize service distribution throughout the district. In addition to suppressing excessive services in surrounding areas, it is also possible to perform appropriate service allocation when operating a large number of vehicles in urban areas. It is also possible to increase the applicability of demand bus systems in urban areas.
