Description

[Technical Field]

[0001] The present invention relates to a diagram creation system and a diagram creation method for transportation such as railways. [Background technology]

[0002] In railway train operations, train operation control systems control train operations across the entire line based on a preset train schedule. Even if the running time for the entire line (between all stations) is the same, the amount of power consumed tends to vary depending on the train schedule that has been established. Therefore, technologies are being adopted to achieve energy-saving operation by devising train operating methods (powering, coasting, braking including regeneration, etc.).

[0003] In addition, technology is being adopted to create energy-saving timetables by devising target times, such as by changing the running time between each station to reduce the overall amount of power consumed between stations.

[0004] As a prior art document, Patent Document 1 discloses a technology for predicting the future congestion level of each vehicle based on the passenger occupancy rate of each vehicle that makes up a train, and for adjusting operations by determining whether or not to change the operation plans of one or more trains in a train timetable that shows the operation plans of multiple trains.

[0005] Furthermore, Patent Document 2 discloses a technology that reduces the train's running speed based on the train's running position and taking into consideration the stopping time at the next stop, so that the train to be controlled arrives at the next stop within the time from the scheduled arrival time at the next stop corresponding to a preset train schedule to the scheduled departure time. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 2023-116914 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-230775 Summary of the Invention [Problem to be solved by the invention]

[0007] In both the technology for energy-saving operation and the technology for energy-saving timetables, the stations at which trains stop are fixed and not intended to be changed. This point is not mentioned in Patent Document 1 or Patent Document 2.

[0008] The amount of power consumption and running time of the entire line will vary depending on which stations are determined as stopping or passing stations for the trains in operation. Therefore, in the current operation schedule, if stations with high power consumption are set as stopping stations, there is a high possibility that energy efficiency will decrease. Also, if the number of trains operating during rush hour or other times is increased, it is expected that the running time of the entire line will increase depending on the relationship between stopping stations and passing stations (including waiting for trains to pass through) and the number of passengers getting on and off at stations.

[0009] Therefore, an object of the present invention is to provide a technology for changing the stations at which trains stop in a train schedule, thereby improving energy efficiency and speed. [Means for solving the problem]

[0010] In order to solve the above problems, one representative timetable creation system of the present invention is a timetable creation system that creates timetables for trains running on a route, and is equipped with an information acquisition unit that acquires various information regarding trains and stations on the route, a stop station determination unit that determines the stop stations on the route for each train based on the acquired various information, and a timetable creation unit that creates a timetable using the determined stop stations for each train as one of the input information. [Effects of the Invention]

[0011] According to the present invention, it is possible to reduce the amount of power consumed on the entire route while keeping the travel time of the entire route the same. Problems, configurations, and effects other than those described above will become apparent from the following description of the preferred embodiments. [Brief explanation of the drawings]

[0012] [Figure 1] FIG. 1 is a functional block diagram showing an example of the configuration of a diagram creation system according to the present invention. [Figure 2] FIG. 2 is a diagram showing an example of the state of the stop stations before and after a change in the stop stations. [Figure 3] FIG. 3 is a diagram showing an example of the transition of evaluation performance before and after a change in a stop station. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, examples of the present invention will be described with reference to the drawings as modes for carrying out the present invention, but the present invention is not limited to these examples. [Example]

[0014] FIG. 1 is a functional block diagram showing an example of the configuration of a diagram creating system 1 according to the present invention. The diagram creation system 1 according to the present invention is composed of an information acquisition unit 11, a stop station determination unit 12, and a diagram creation unit 13. The train schedule created by the diagram creation unit 13 is transmitted as an output of the diagram creation system 1 to trains 20 on the target line.

[0015] A. Information Acquisition Unit 11 The information acquisition unit 11 acquires various types of information related to the operation of each train running on a target line. The various types of information related to the operation of each train include, for each train, the amount of power consumed, running time, stopping time, occupancy rate, maintenance information, overtaking information, and ride comfort, as well as, for each station on the line, information such as the number of passengers getting on and off, congestion level, and whether the station is a passing station, a stopping station, or a transfer station.

[0016] Among the train-related information described above, the power consumption can be obtained by, for example, calculating the power consumption using the running characteristics of each train retrieved from a memory unit that stores the running characteristics of each train, and the occupancy rate can be obtained by, for example, calculating the load on the vehicle and the vehicle weight obtained by measurement. However, since the sources and methods of obtaining the above-mentioned various types of information are outside the scope and not the purpose of the present invention, no further mention will be made of them.

[0017] B. Stop Station Determination Unit 12 The stop station determination unit 12 receives as input the various types of information acquired by the information acquisition unit 11, and when focusing on energy efficiency, uses the amount of power consumed by each train operating on the route as the evaluation performance, or when focusing on speed, uses the running time of each train operating on the route as the evaluation performance.The stop station determination unit 12 then determines the stops for each operating train based on at least one of the evaluation performances described above, and changes the stop stations.

[0018] Here, the trains for which stopping stations are determined may be all trains in operation, or specific trains identified by, for example, narrowing down the operating time period (morning, afternoon, rush hour, etc.) or narrowing down the train type (limited express, express, rapid, etc.).

[0019] Furthermore, the amount of power consumption or running time for each train operating on a route, which is the evaluation performance, is expected to increase or decrease due to changes in the state of the various information acquired by the information acquisition unit 11. Therefore, the stop station determination unit 12 uses the various information whose state changes as parameters and considers the impact of the state changes on the increase or decrease in the evaluation performance, thereby determining the evaluation performance and deciding the stop stations in a manner that is suited to the operating environment, etc.

[0020] Parameters to be considered include, for trains, passenger occupancy rate, maintenance information, overtaking information, and ride comfort, and for stations, the number of passengers boarding and alighting, congestion level, and whether or not there are transfers. To give a specific example, if it is possible to reduce the passenger occupancy rate of trains by changing the stations they stop at, it will be possible to reduce the amount of energy consumed by each train operating on the line or the running time. Also, if it is possible to alleviate the congestion level at stations by changing the stations they stop at, it will be possible to reduce the amount of energy consumed by each train operating on the line or the running time.

[0021] The parameters to be considered may be determined according to the intentions of the railway operating company. Furthermore, the number of parameters to be considered may not be one, but multiple parameters. When multiple parameters are used, weighting may be assigned to each parameter.

[0022] Furthermore, when determining whether to change the stop stations based on the evaluation performance, the stop station determination unit 12 may determine whether to change the stop stations on the condition that the convenience of passengers on the specified or all trains is maintained or improved with respect to at least one of the time period for which the stop stations are changed, the total travel time required for passengers on the specified or all trains in question, and the ability to meet passenger demand (e.g., reservation information for reserved seats) for the specified or all trains in question.

[0023] in particular, - For the time periods when the stops are changed, the appropriateness and effectiveness of changing the stops is determined taking into account the train's operating hours (for example, taking into account passenger needs and convenience during the train's operating hours).

[0024] Determine whether changing stops can reduce the total passenger journey time for a given or all trains in question within the allowable time range.

[0025] - For a given or all trains in question, determine whether the supply capacity to meet passenger demand is within a range that can be satisfied (for example, whether the concentration (bias) of reserved seat reservations has been eliminated).

[0026] C. Diagram Creation Department 13 The diagram creation unit 13 uses the information on the stops for the operating trains determined by the stop station determination unit 12 as one piece of input information for creating a train diagram, and creates a train diagram for the corresponding line based on this input information, including other input information related to train operation. The diagram creation unit 13 transmits the created train diagram as an output of the diagram creation system 1 to the trains 20 on the corresponding line.

[0027] Next, an example of how the stop stations for an operating train are changed by the stop station determination unit 12 will be described. Figure 2 is a diagram showing an example of the state of the stop stations before and after a change in the stop stations. In the diagram, the change in the stop stations of trains 1 to 4 from station A to station G is shown as (a) before the change and (b) after the change. Stop stations are marked with ●, and of the changed stop stations, stations that have been changed to through stations are marked with dotted circles, and stations that have been changed to stop stations are marked with ■.

[0028] Here, the change in the stations shown in Figure 2 is based on the premise that the number of trains stopping at each of stations A to G will not change, in order to ensure convenience for station users (specifically, four trains at stations A, D, and G, and two trains at stations B, C, E, and F). In other words, it is based on the premise that the running times of the entire line will remain consistent, at the very least.

[0029] (1) Train 1 Before the change, the train stopped at every station from Station A to Station G, but after the change, Stations C and F were changed to passing stations. As a result, the amount of electricity consumed by Train 1 in the section from Station A to Station G will be reduced because it will no longer need to slow down, stop, and start at two stations (Station C and Station F). In addition, the running time will also be reduced by the amount of time it will have to stop at two stations (Station C and Station F).

[0030] (2) Train 2 Before the change, the train stopped at stations A, D, and G, but after the change, it will now stop at station C. As a result, for Train 2, the amount of power consumed in the section from station A to station G will increase by the amount of deceleration, stopping, and starting for one station (station C). In addition, the running time will also increase by the amount of time spent stopping at station C.

[0031] (3) Train 3 Before the change, the train stopped at every station from Station A to Station G, but after the change, Station B was changed to a passing station. As a result, for Train 3, the amount of power consumed in the section from Station A to Station G will be reduced because there will be no need to slow down, stop, and start for one station (Station B). In addition, the running time will also be reduced by the amount of time it stops at one station (Station B).

[0032] (4) Train 4 Before the change, trains stopped at stations A, D, and G, but after the change, they will now stop at stations B and F. As a result, for Train 4, the amount of power consumed in the section from station A to station G will increase due to the additional deceleration, stopping, and starting required for two stations (stations B and F). In addition, the running time will also increase due to the stops at two stations (stations B and F).

[0033] When changing the stop stations shown in Figure 2, the stop station determination unit 12 changes the stop stations in the current timetable by determining the stop stations based on the evaluation performance (power consumption or running time for each train operating on the route) shown above.

[0034] In this case, one or more supplementary parameters for the evaluation performance are taken into consideration as necessary, such as the congestion level (occupancy rate) of each train when trains 1 to 4 are in operation, the station congestion level at stations A to G during the operating hours of trains 1 to 4, the satisfaction level of passenger demand (for example, train seat reservations) totaled for trains 1 to 4, and the total travel time required by passengers.The evaluation performance is judged based on these considerations, and a decision is made to change the stations that the trains stop at.

[0035] Figure 3 is a graph showing an example of the change in evaluation performance before and after a change in the stations where the trains stop, where the evaluation performance is the amount of power consumed by trains operating on the route (hereinafter simply referred to as "power consumption"). With the vertical axis representing the amount of power consumed and the horizontal axis representing the amount of power consumed before and after the change in the stations where the trains stop, the graph shows the change in the amount of power consumed by each of trains 1 to 4 shown in Figure 2, and the change in the amount of power consumed by all four trains combined.

[0036] Looking at the trends in the amount of electricity consumed by trains operating on each line (Train 1 to Train 4) individually, as shown in (1) to (4) above, for Train 1, the amount of electricity consumed decreased because the number of stations it stopped at decreased by two, for Train 2, the amount of electricity consumed increased because the number of stations it stopped at increased by one, for Train 3, the amount of electricity consumed decreased because the number of stations it stopped at decreased by one, and for Train 4, the amount of electricity consumed increased because the number of stations it stopped at increased by two.

[0037] However, it can be seen that the increase or decrease in the amount of electricity consumed by each train differs depending on factors such as the occupancy rate and stop time of each train due to differences in the number of passengers boarding and alighting at each station (Station A to Station G) during the operating hours of each train (Train 1 to Train 4).As a result, it can be seen that the total power consumption of the four trains has decreased over time.

[0038] Figure 3 shows the case where the evaluation performance is the amount of power consumed by each train operating on the line. However, if the evaluation performance is the running time of each train operating on the line, the changes in the running time of each train before and after the stop change and the changes in the running time of all trains can also be shown as trends.
