摘　　要：[目的]市域(郊)铁路是我国轨道交通体系四网融合发展的短板,其在功能定位、客流需求等方面尚未达成共识,这也导致了市域(郊)铁路信号系统制式的选择存在一定的困难和问题,需要对此进行深入研究。[方法]阐述了市域(郊)铁路在多层次轨道交通的融合需求、运营需求,分析了其在运营管理、设备选型上存在的问题。并以无锡至宜兴城际轨道交通工程为案例,对比了国铁CTCS-2(中国列车控制系统2级)+ATO(列车自动运行)系统、城轨CBTC(基于通信的列车控制)系统的特点,对二者在市域(郊)铁路的适应性进行了分析。基于该线跨线运行至苏锡常城际铁路的需求,对该线的信号系统设计方案进行了研究。[结果及结论]案例线路宜采用以CBTC系统为基础、兼容CTCS-2+ATO系统的信号系统方案。该方案既可保证市域(郊)铁路具有公交化运营的能力和高的自动化等级,同时也可满足列车跨线运行至国家铁路时信号系统的兼容需求。[Objective]City(suburban)railways are a weak link in the four-network integrated development of rail transit system in China.There is currently no unified understanding regarding their functional positioning and passenger flow demands.This lack of consensus leads to difficulties and issues in selecting formats for city(suburban)railway signaling system,calling for in-depth research.[Method]By elucidating the integration and operation requirements of city(suburban)railways in a multi-level rail transit system,the problems existing in operation management and equipment type selection are analyzed.Using the Wuxi-Yixing Intercity Rail Transit project as a study case,the characteristics of China Railway CTCS-2(China Train Control System level 2)+ATO(automatic train operation)system and the urban rail CBTC(communication-based train control)system are compared.The adaptability of these systems in city(suburban)railways is analyzed.Based on the demand for cross-line operation with Suzhou-Wuxi-Changzhou intercity railways,the signaling system design scheme for Wuxi-Yixing Intercity Rail Transit is investigated.[Result&Conclusion]The signaling system scheme based on CBTC system,with compatibility for CTCS-2+ATO system is suitable for the case line.This scheme ensures the city(suburban)railways capabilities for mass-transit type operation and a high level of automation,but also meeting the compatibility requirements for the signaling system when trains operating across lines to national railways.
