Network-based train-following model and study of train's delay propagation

描述了一种移动闭塞下考虑不同类型列车混跑时基于元胞自动机的列车追踪模型.将该模型应用到铁路网,模拟了网络条件下列车运行情况.应用该模型模拟了移动闭塞下列车延迟传播的现象.分析了发车间隔松弛时间、初始延迟时间等因素对列车延迟的影响.将该模型的模拟结果和理论公式的计算结果进行了比较,验证了模型的可靠性和有效性.

Based on the cellular automaton concept, this paper presents a train-following model for the moving block system with different types of trains running. We apply the model to the rail network and simulate the running of trains. We also simulate the traffic phenomenon of delay propagation in moving block system. We investigate how the main factors including train deliver time interval and initial delay affect the delay propagation of trains. The simulation results are compared with the theoretical results to verity the reliabity and feasibility of the model.
