Algorithm Design and Simulation of the Urban Rail Turn-Back Capacity Based on CBTC

In order to analyze the turn-back capacity of urban rail transit based on CBTC more accurately, firstly, this paper analyzes the turn-back process and characteristics, and the factors that influence the turn-back interval time. Secondly, it respectively analyzes various influence factors and designs algorithm. Then, it designs algorithm and developed computer simulation system (TBSim) for calculating the turn-back capacity based on CBTC and the traction calculation. Finally, it proves the correctness and practicability of the algorithm and the simulation system by an example.

CTCS制式下短编组列车自动折返快速停车方案研究

目前我国的动车组有4节编组、8节编组、16节编组等多种编组形式。在短编组列车进入折返线进行站后自动折返作业时,为缩短列车折返时间,应使短编组列车尽快停车,且车尾应尽量靠近折返信号机。基于CTCS(中国列车运行控制系统)制式,从轨旁信号设备的布置、信号系统的配套修改等方面,对原设计方案提出了6个优化方案,并进行了仿真。通过对仿真结果的对比分析,推荐采用在折返线中间加分隔信号机的方案。
