DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, a train operation management system according to Embodiment 1 of the present invention will be described with reference to the accompanying drawings. In the drawing, the same reference numerals as those in FIG. 3 indicate the same or corresponding parts. In FIG. 1, reference numeral 7A denotes a central management unit according to the first embodiment. The central management unit 7A grasps the current position of each train based on the train operation information acquired from the central computer system 1 in addition to the configuration of the conventional central management unit 7, and the train operation is disturbed. At the time, the train operation simulation unit 9 that predicts the on-rail position of each subsequent train after the turbulence and creates a prediction diagram,
The train getting on and off status of each time zone is recorded as data, and the train getting on and off database 10 and the train operation simulation unit 9 for updating and recording this data every time a passenger survey at a station is conducted once a year, for example. From the train location and the train getting on / off database 10 predicted in the future, according to a certain algorithm, the train arrival time interval to each station at the time of train operation disturbance is made as close as possible to the normal time as much as possible, and the arrival delay time at each station is reduced. In addition to deciding the train rescheduling plan (change of train operation sequence, change of operation section, etc.) so as to be even, a part of the diagram reflecting the decided traffic rescheduling plan and the relevant traffic rescheduling plan The traffic control plan decision unit 11 that changes the train schedule, the predicted train schedule created again by the train operation simulation unit 9 based on the changed train schedule Based train of the station (local station)
And a guide device 12 for guiding an estimated time of arrival at a main station (a station in the metropolitan area) to a station waiter through the transmission device 4a.

Next, the operation of the first embodiment will be described with reference to the flowchart shown in FIG. This flowchart shows processing for making the arrival time intervals of the train to each station as close as possible to normal times as much as possible when train operation is disrupted, and for making the arrival delay time at each station small and uniform. The operation when the train operates normally and the operation when the central computer system 1 goes down are the same as the operations described in the related art.

Due to bad weather or personal injury,
When the operation of a predetermined train is disrupted, the train operation simulation unit 9 predicts the future on-rail position of the subsequent train and creates an estimated timetable. Based on the predicted timetable and the status of train getting on and off at each station and each time zone stored in the train getting on and off database 10 at normal times, the traffic control plan determining unit 11
Then, the train arrival time interval to each station, which is a passenger getting on and off condition, is set to be as close as possible to normal time at each station and each time zone as much as possible so that the arrival delay time of the train to each station is reduced and the arrival delay time is made uniform. Determine a train rescheduling plan.

Examples of the traffic control plan include a change in train operation order and a change in operation section. By such a change, each subsequent train can be connected to a train in front of the other, for example, in a daisy chain, and it is possible to minimize the possibility of repetition of low-speed operation or suspension of operation.

When the traffic rescheduling plan is determined, the train operation simulation unit 9 creates a predicted timetable reflecting the traffic rescheduling plan (step S1), and simulates the operation of the train using the predicted timetable.

From the result of the train operation simulation,
In order to alleviate the congestion of passengers at the platform, the number of trains that arrive at each station every n minutes at each time slot is obtained (step S2). Next, the train getting on and off database 10
The number of trains arriving every n minutes at each station determined from the getting on and off state of each train in each time zone at each station and main station stored in each station and each station obtained from the result of simulation of train operation by expected timetable The number of trains arriving per n minutes is compared (step S3).

If it is determined that the results of the comparison are equal, even if the train is operated on a predicted timetable, the arrival time interval of each train to the station is determined by the train arrival estimated from information stored in the train getting on / off database. If it is determined that the time interval is the same, the process ends (steps S4 and S4).
10).

However, the arrival time interval of each train at the station and the main station estimated from the predicted timetable is not the time interval estimated from the train getting on / off database 10 due to a delay of a subsequent train or the like, but the arrival time of the train at each station. If it is determined that the time interval varies and that the time interval between the arriving trains is longer than n minutes depending on the main station, at least one train arrives at the n-minute interval for each main station. The traffic control plan is changed (Step S5). As a result, the train arrival time intervals at each main station can be equalized.

Based on the change in the traffic control plan, each major station
The train operation simulation unit 11 creates a forecast schedule so that at least one train arrives at minute intervals, and at least one train arrives at each corresponding station other than the main station at m-minute intervals longer than n minutes. Fix (step S6). In this way, the operation of the train is simulated based on the predicted timetable recreated, and it is determined whether at least one train has arrived at each corresponding station other than the main station at an interval of m minutes (step S7).

As a result of the simulation, if it is determined that the train arrives at an interval of m minutes, the changed predicted timetable is transmitted to the central processing system 1 (step S9), and the train is operated with the changed predicted timetable. Is started, and the estimated time of arrival at the station and the main station is guided to the passengers of each station through the guidance device 12 based on the changed predicted timetable (step S11).

However, if it is determined in step S7 that the train does not arrive at the station at an interval of m minutes, the traffic rescheduling plan determination unit 11 changes a part of the driving sequence which is the traffic rescheduling plan. At least 1 minute at m-minute intervals
Change part of the schedule so that the book arrives. The train operation simulation unit 9 creates a predicted timetable again based on the changed timetable and simulates the operation of the train (steps S6 to S8).

Steps S6 to S8 are repeated until it is confirmed that at least one train arrives at each station at m-minute intervals. When it is confirmed that the vehicle arrives at step S7, the changed predicted timetable is transmitted to the central computer system 1 (step S9), and the estimated time of arrival at the station and the main station is determined based on the changed predicted timetable. The passengers at each station are guided through the guidance device 12 (step S11). As a result, it is possible to accurately inform the waiting passengers at the station of the estimated arrival time of each train, so that it is possible to prevent concentrated riding on a specific train.
