不同闭塞方式下城轨列车追踪运行过程及其仿真系统的研究

介绍了城市轨道交通不同信号闭塞方式及其追踪列车间隔时间的计算方法,建立了多列车追踪运行的仿真系统,并进行了算例的设计。在算例中,通过对两列车在固定闭塞、准移动闭塞、移动闭塞方式下的追踪运行模拟,分析了不同闭塞方式下列车追踪运行的效果,同时利用仿真系统对最小追踪列车间隔时间进行了验算,并得出相同发车间隔情况下不同信号闭塞方式的列车追踪运行结果以及三种闭塞方式条件下最小追踪列车间隔时间的计算结果。该系统可以为科研、设计人员进行城市轨道交通列车安全间隔及通过能力等方面的研究提供便利条件。

Study on Tracking Operations Between Trains of Different Block Modes and Simulation System

This paper introduces different signal block modes and the method which was used to calculate tracking intervals between trains, and establishes simulation system for multi-train tracking. A case was designed for analysis. In the case, based on the simulation of tracking operations of two trains under the modes of fixed-block, moving-like block, and moving block, the paper analyses effects of tracking operations of different block modes, and checks the minimal tracking intervals between trains with simulation system. Results of different signal block modes with the same time interval, and calculated results of minimal tracking intervals between trains of the three modes are given. This system is able to a reference for the researchers and designers who work in the field of urban railway safe intervals and carrying capacity study.
