Description

  Embodiments described herein relate generally to an operation curve creation device.

  The train schedule is created according to a preset reference operation time and a continuation time interval. The reference operation time and the continuation time interval are obtained based on the operation curve. Therefore, the creation of an operation curve is an important factor in creating a train schedule. Here, the driving curve is a curve representing the speed of a train at an arbitrary point between stations. Usually, the operation curve is the shortest required time between stations, with train characteristic information indicating the characteristics of trains traveling between stations, ground facility information indicating ground facilities related to train travel between stations as constraints ( (Hereinafter referred to as “minimum driving time”).

  Then, the time required for the travel time of the train between stations according to the operation curve (that is, the minimum operation time) and the allowance time are taken as the reference operation time. In addition, when the train is operated according to the operation curve and the traffic signal at each point between the stations is passed at the maximum display or maximum speed, the operation interval with the preceding train is set as the continuation interval. By setting the reference operation time and the continuation time interval in advance for each vehicle type and train type of the train traveling between the stations, the train diagram creation process can be made more efficient.

  By the way, considering the operation of trains with high-density schedules from the viewpoint of improving transportation capacity, it is possible to shorten the continuation interval by passing traffic lights between stations below the maximum display or below the maximum speed. Is possible. Therefore, running a train between stations with the minimum amount of time is not always the best train operation method. And in order to create an operation curve that does not run the train between stations with the minimum operation time, the creator of the operation curve creates an operation curve created so that the train can run between stations with the minimum operation time. Need to edit.

  However, when editing a driving curve, the creator must proceed with the editing work assuming that the editing of the driving curve will affect the standard driving time and the continuation interval. Have difficulty. Furthermore, when creating a train operation curve with a high-density diagram, the creator needs to create a large number of operation curves and repeatedly consider the continuation time interval, which is not realistic from the viewpoint of work efficiency.

  The operation curve creation device of the embodiment includes a creation unit, a calculation unit, and a display control unit. The creation unit creates an operation curve of a train traveling between predetermined stations. Based on the driving curve of the preceding train and the driving curve of the continuation train that runs after the preceding train, the calculation unit calculates the driving time interval between the preceding train and the continuation train at the point where the traffic signal between the predetermined stations is installed. Until the traffic signal becomes the second display other than the first display on the basis of the first display of the traffic signal when the continuing train passes the point after the calculated driving time interval after the preceding train The change time of is calculated. The display control unit displays a screen including the operation curve and the change time of the continuing train on the display unit.
