CBTC系统列车运行间隔控制仿真研究

Research on Simulation of Train Headway in CBTC System

在城市轨道交通中,列车运行间隔过大会降低线路行车效率,过小又将影响列车运行安全;因此,合理调整列车运行追踪间隔,在保证列车安全运行的同时提高线路行车效率,是目前CBTC系统列车运行间隔控制的关键。本文介绍了影响列车运行间隔的因素以及列车运行间隔的计算方法,并对列车运行追踪距离建立仿真;通过静态仿真对发车间隔、停站时间等影响列车运行间隔的参数取值,并验证取值是否合理;通过研究列车运行情况,根据实时位置关系调整列车运行间隔并进行动态仿真。

In urban tion in a line while rail transit, too large train headway will reduce the efficiency of train opera- too small train headway will affect the safety of train operation. Therefore, reasonably adjusting the same time, and train headway can ensure safe train operation and high traffic efficiency at is the key of train headway control for a communication-based train operation control system （CBTC）. The factors affecting the train headway and the calculation method of train headway are introduced. In addition, a simulation of train headway is established. Through static simulation, the parameters such as departure interval and stop time affecting train headway are verified to check whether their values are reasonable. By studying the situation of train opera- tion, train headway can be adjusted according to real-time train position and dynamic simulation is conducted.
