The invention provides a dynamic train tracking interval calculation method, which comprises the following steps of: establishing a space-time speed network model for each train in a current transportation scene according to basic static data of the train and dynamic data in the transportation scene; marking space-time resources occupied by each network arc in the space-time speed network models of all trains according to a locking time theory; according to the train departure sequence, searching the shortest space-time speed path of each train in the marked space-time speed network model in sequence, and when space-time resources occupied by a network arc are used resources, forbidding selection when the shortest space-time speed path is searched; and after all the trains are painted, obtaining the minimum tracking interval between the trains and a corresponding speed curve according to the searched space-time speed path result. According to the method, the minimum tracking interval between the high-speed railway trains is calculated in any transportation scene, and meanwhile, the feasible recommended speed curve of the minimum tracking interval is obtained through the calculation result.
本发明提供了一种动态列车追踪间隔计算方法,包括:根据列车基础静态数据和运输场景下的动态数据,对当前运输场景下的每个列车建立时空速度网络模型;根据锁闭时间理论,对所有列车的时空速度网络模型中各网络弧所占用的时空资源进行标记;根据列车发车顺序,在标记后的时空速度网络模型中,依次搜索每个列车的最短时空速度路径,当网络弧占用的时空资源为已使用资源,则在搜索最短时空速度路径时禁止选用;铺画所有列车后,根据搜索的时空速度路径结果得到列车间的最小追踪间隔以及对应的速度曲线。本方法实现了在任意运输场景下计算高速铁路列车间的最小追踪间隔,同时通过计算结果得到了最小追踪间隔可行性的推荐速度曲线。
