关于新一轮都市圈轨道交通线路规划与设计的几点思考

Reflections on New Round Planning and Design of Metropolitan Circle Rail Transit Lines

《上海市城市总体规划(2017—2035年)》提出构建“3个1000公里”的轨道交通网络,适应多层次空间差异化发展需求。按照“一张网、多模式、广覆盖、高集约”的规划理念,构建由城际线、市区线、局域线三个层次的轨道交通网络。在这里,市域(郊)铁路和轨道快线依据其功能,统一暂称为“市域线”。从国际大都市圈城市轨道交通发展历程来看,随着城镇化从单中心城市向多中心都市圈、城市群演化,城市轨道交通发展重点将从市区线逐渐向市域线和局域线两端延伸。

Shanghai Master Plan(2017-2035)has proposed construction of'three-1000 km'rail transit network to adapt to its demand of multi-level spatially differentiated development.According to the planning concept of'one network,multiple modes,wide coverage,high intensificationz,rail transit network consisting of three levels of intercity line,urban line,local line is established.In this context,the suburban railway and rapid rail are unified under category of'suburban line',because of their functionalities.The history of international metropolitan urban rail transit development reveals that with evolution of urbanization from single-center city to multi-center metropolitan circle and urban cluster,urban rail transit development emphasis will extend from urban line to both ends of suburban line and local line.
