基于车车通信系统的折返能力研究

Study on Turn-back Capacity Based on TACS

折返能力一直以来都是城市轨道交通运营能力的瓶颈点。通过分析典型折返站的折返过程,在新一代基于车车通信的信号控制系统(TACS)基础上,提出对道岔资源进行细分与优化道岔控制的方案来提升折返能力。最终可以将折返能力较基于通信的列车控制系统提升25%以上,使城市轨道交通运营间隔达到90 s以内。

The turn-back capacity has always been a bottleneck in the operational capacity of urban rail transit.This paper analyzes the turn-back process of a typical station and proposes a plan of subdividing and optimizing turnout control based on the new generation of train-to-train communication signaling control system to improve the turn-back capacity.Through this method,the turn-back capacity can be increased by more than 25%compared with CBTC system,making the operation interval of urban rail transit less than 90 seconds.
