SYSTEM TO DETERMINE POSITIONS TO BUILD SIGNALS AND METHOD FOR THE SAME

PROBLEM TO BE SOLVED: To provide a system to determine positions where signals are built which is able to determine an arrangement of signals efficiently by which a targetted time interval is realized.SOLUTION: In an embodiment of a system to determine positions where signals are built, means to determine positions where signals are built arranges a distance-time curve of an end edge of a preceding train and another distance-time curve of a front edge of a train following the preceding train while keeping a targetted time interval between both curves, acquires a first time at which the end edge of the preceding train exists at the first signal position on the basis of the distance-time curve of the end edge of the preceding train, acquire not only a first position at which the front edge of the following train exists at the first time on the basis of the distance-time curve of the front edge of following train, but also a first velocity of the following train on the basis of the operation curve of the following train (the operation curve is a velocity-distance curve), acquire a braking curve of the following train that runs at the first velocity at the first position on the basis of the track information and the train performance information (the braking curve is a velocity-distance curve), and determine a second position where the velocity of the following train reaches a prescribed value as the position that a second signal is built on this side of the first signal.SELECTED DRAWING: Figure 1 【課題】目標とする時隔値を実現するための信号機の配置を効率的に決定することができる信号機建植位置決定システムを提供する。【解決手段】実施形態によれば、信号機建植位置決定システムは、建植位置決定手段が、先行列車の終端位置の時間曲線と、続行列車の先頭位置の時間曲線とを、目標時隔値分の間隔となるように配置し、先行列車の終端位置の時間曲線に基づき、先行列車の終端が第１の信号機の地点に位置する第１の時刻を取得し、続行列車の先頭位置の時間曲線に基づき、第１の時刻において続行列車の先頭が位置する第１の位置を取得すると共に、続行列車の運転曲線に基づき、続行列車の第１の速度を取得し、線路情報と列車性能情報とに基づき、第１の位置を第１の速度で走行する続行列車の制動曲線を取得し、続行列車の速度が所定の値なる第２の位置を第１の信号機の手前に建植する第２の信号機の位置に決定する。【選択図】図１
