市域轨道交通网络化运营信号系统技术应用及方案选择

Technological Application and Scheme Selection of City Rail Transit Networking Operation Signaling System

目的:目前,市域轨道交通信号系统制式的选择面临较大的困难,信号系统制式对线路运营组织管理模式具有决定性的作用,因此有必要对影响市域轨道交通信号系统的相关因素进行深入研究,选择适宜的信号系统制式。方法:介绍了现有信号系统制式选择存在的问题;介绍了我国主要的信号系统制式;对信号系统制式方案的选择因素进行了分析,并总结了选择信号系统制式方案时需考虑的因素。结果及结论:现有的CBTC(基于通信的列车控制)信号系统及CTCS2(中国列车控制系统C2级)系统不能完全匹配市域轨道交通公交化运营及线网互联互通的运营要求;目前,可供市域轨道交通选择应用的主要信号系统制式包括CBTC信号系统制式、CTCS2信号系统制式及STCS(市域轨道交通列车控制系统)兼容型信号系统制式;市域轨道交通信号系统选择因素大体可分为系统技术限制因素、运营管理模式因素、网络化运营需求因素等决定性因素,线路客流特征、投资效益、设备故障影响等重要因素,以及技术发展、乘客体验、服务舒适性、安全性、外部环境影响等其他因素。

Objective:Currently,the signaling system format selection of city rail transit is facing significant challenges due to its crucial role in determining the line operation organization-management mode.Therefore,it is necessary to conduct in-depth research on relevant factors that influence the city rail transit signaling system and select an appropriate signaling system format.Method:The problems existing in the selection of signaling system formats are introduced,together with the main signaling system formats in China.The factors affecting this selection are analyzed,and the considerations for choosing a signaling system format are summarized.Result&Conclusion:The existing CBTC(communication-based train control)signaling system and CTCS2(Chinese train control system 2)cannot fully meet the operational requirements of city rail transit in terms of public-transit-oriented operations and network interoperability.Currently,the main signaling system formats available for city rail transit include CBTC,CTCS2,and STCS-compatible(signaling and train control system).The factors influencing the selection of city rail transit signaling system can be broadly categorized into determinative factors such as system technical limitations,operation-management mode,and networking operational requirements,as well as important factors such as passenger flow characteristics,investment efficiency,equipment failure impact,and other factors including technological development,passenger experience,service comfort,safety,and external environmental impacts.
