通过优化信号系统ATO控车策略提升地铁6编组列车旅行速度的研究分析

Research and Analysis on Improving Train Travel Speed of Metro 6 Marshalling Trains by Optimizing ATO Control Strategy of Signal System

城市轨道交通作为公共交通最重要的交通工具,除了要解决列车运行过程中的安全问题,提高线路运行效率也是城市轨道交通的基本需求之一。运输效率是提高客运服务水平,降低运营成本的关键。旅行速度是运输效率中很重要一个因素,因此在线路条件允许的情况下,通过对信号系统的改进,缩短列车在区间的运行时间,减少旅客的站台等待时间是很有意义的。为检验系统设计和工程实施的运输能力,该文通过研究和分析信号系统的ATO控车策略来提升6B编组列车在呼和浩特1号线的旅行速度。通过对信号系统进行优化,改进控车设计方案,研究6B编组列车达到36 km/h旅行速度要求的可行性。

As the most important means of public transport,urban rail transit not only needs to solve the safety problems in train operation,but also needs to improve the efficiency of line operation.Transport efficiency is the key to improve passenger service level and reduce operating cost.Travel speed is an important factor in transportation efficiency.Therefore,it is meaningful to shorten the running time of trains and reduce passengers’waiting time on the platform by improving the signal system if the line conditions permit.In order to test the transportation capacity of the system design and engineering implementation,this paper studies and analyzes the ATO vehicle control strategy in the signal system to improve the travel speed of the 6B train in Hohhot Line 1.By optimizing the signal system and improving the design scheme,the feasibility of 6B marshalling trains to meet the travel speed requirement of 36 km/h was studied.
