城市轨道交通列车折返能力综合优化分析

Comprehensive Optimization Analysis of Turn-back Capacity In Urban Rail Transit

随着城市轨道交通运营间隔不断缩短,列车编组的加长,如何提升折返能力成为制约城市轨道交通运营能力的关键因素之一。提出一种针对城市轨道交通列车折返能力综合优化的方法,首先对列车折返过程进行分析,依照列车的不同运行状态对折返过程进行重新归纳,然后提出基于列车不同运行状态的折返能力综合优化分析图,最后根据该分析图对列车折返过程进行初步优化,并通过仿真验证结果表明该分析方法的有效性。

With the developing trend of shorter train headway and more cars coupling, how to improve the turn-back capacity is one of key factors restricting the operation capacity of urban rail transit. This paper presents a comprehensive optimization method to improve train turn-back capacity based on analyzing the turn-back process and summarizing different operation states of the train, and puts forward a turn-back capability comprehensive optimization analysis diagram according to different train operation states. The simulation results show that the analysis diagram has the validity for optimizing the train turn-back process.
