北京市郊铁路发展初探

市郊铁路系统是世界级城市轨道交通系统的重要组成部分，也是发达国家和城市满足长距离交通需求的主要手段。面对北京市城市规模扩大以及京津冀区域协同发展的要求，探讨如何发展北京市郊铁路并使之与城市轨道交通形成有机的整体。首先分析伦敦、纽约、巴黎、东京4个世界级城市的中心集聚强度以及市郊铁路对城市运行的支撑作用。同时，回顾这4个城市的市郊铁路发展历史进程，总结其网络布局特点及经验教训。在此基础上，提出北京市郊铁路发展的原则和思路，强调与现有及规划铁路资源在运营上互联互通，同时建立铁路与城市轨道交通一体化管理、运营体系。

Discussion on Beijing Suburban Railway Development

Suburban railway is an important component of rail transit system in world-class cities. It is also commonly used to accommodate long-distance travel demands in developed countries and cities. Confront-ing with the Beijing expansion and the Beijing-Tianjin-Hebei joint-development needs, this paper investi-gates how to develop an integrated Beijing suburban railway network with the urban rail transit system. The paper first discusses the high gathering intensity in urban central and the role of suburban railway in supporting urban development in four world-class cities such as London, New York, Paris and Tokyo. By reviewing the development of suburban railway in the four cities, the paper summarizes the characteristics of network layout and learned experiences/lessons. Based on the proposed four principles and development concepts for suburban railway development in Beijing, the paper emphasizes the interconnection between suburban railway and existing/planned railway, and development of an integrated system for railway and urban rail transit management and operation.
