摘要:
                    [目的] 随着市域铁路的网络化发展,对其信号系统互联互通能力和最小间隔时间提出更高要求。目前我国现有市域铁路信号系统主要采用CTCS⁃2+ATO(中国列车控制系统2级+列车自动运行)和CBTC(基于通信的列车控制)两种方案,结合上海市域铁路的网络化发展现状,需对上述两种方案进行对比分析,提出适用于上海市域铁路网的信号系统选型建议。 [方法] 分析上海市域铁路网规划背景和网络化运营需求,总结国内典型城市的市域铁路建设经验,多角度对比CTCS⁃2+ATO与CBTC的技术特性及适用性差异;通过量化分析两个系统运行效率的关键影响因素,并借助仿真手段验证其实际性能表现;围绕上海市域铁路的互联互通需求,从“与国铁系统兼容性”“跨省市域铁路协同性”“内部线路网络化能力”3个方面展开分析,并评估不同系统在互联互通场景下的适应性。 [结果及结论] 上海市域铁路网对线网效率和互联互通均有需求,而CBTC虽能体现较高的运行效率,但互联互通能力较弱;CTCS⁃2+ATO虽能体现较好的互联互通性能,但对时间间隔的进一步提升能力存在不足,对满足远期运能有较大承压。故建议上海市域铁路线网与外部互通的线路采用CTCS⁃2+ATO系统,对运能要求高的内部线路可采用CBTC系统,以满足线网效率和互联互通需求。

                    [Objective] With the rapid networked development of city railways, higher demands are being placed on the railway signaling systems in terms of interoperability and minimum headway. Currently, the main signaling system solutions for city railways in China are the CTCS-2 (China train control system level 2) + ATO (automatic train operation) system and CBTC (communication-based train control) system. Targeting the current state of networked development in Shanghai city railway network, it is necessary to conduct a comparative analysis of these two solutions and propose suggestions on signaling system selection for Shanghai city railway network. [Method] The planning background and networked operational requirements of Shanghai city railway network are analyzed, and the construction experiences of city railways in major Chinese cities are summarized. The technical characteristics and applicability differences between CTCS-2 + ATO and CBTC systems are compared from multiple aspects. Through quantitative analysis of the key factors affecting system operational efficiency, simulation methods are employed to verify their actual performance. Considering interoperability needs of Shanghai city railway, the adaptability of each system in interoperability scenarios is evaluated from three perspectives: compatibility with the national railway system, city railway synergy cross provinces and network integration capability within internal lines. [Result  Conclusion] Shanghai city railway network requires both high network efficiency and interoperability. However, with demonstrated superior operational efficiency, the CBTC system has weaker interoperability capabilities. Conversely, the CTCS-2 + ATO system exhibits better interoperability performance but has limitations in further reducing headways, which imposes pressure on meeting long-term capacity demands. It is therefore recommended that Shanghai city railway lines connecting with external networks adopt the CTCS-2 + ATO system, while internal lines with high capacity requirements use the CBTC system to meet both current efficiency and interoperability demands of the network.
