面向长三角一体化的典型节点城市轨道交通协同规划实践——以嘉兴市为例

Collaborative Planning Practice of Typical Node Cities' Rail Transit Facing the Integration of Yangtze River Delta:a Case Study of Jiaxing

针对长三角城市群的中小城市轨道交通模式不确定、层次不清晰、功能易混乱问题,通过浙江省嘉兴市实例提出协同规划措施。从“区域―市域―城市”3个层面对轨道交通发展进行必要性分析,提出借势都市圈城际铁路发展规划市域铁路建设,推动都市圈城际铁路和市域(郊)铁路“两网合一”是重中之重,同时在中心城区构建高品质网络的低运量轨道交通网络。嘉兴市轨道交通规划布局注重“区域协同、互联互通、中心直连、控制规模”,规划形成“三主、两辅、五联”的市域铁路网络及网格放射状的现代有轨电车网络,支撑嘉兴市“外融、内聚、强心、生态”的发展要求。文章通过实例分析,以期为其他同类型城市提供参考。

Aiming at the problems of uncertain rail transit mode,unclear level and easy confusion of functions in small and medium-sized cities in the Yangtze River Delta urban agglomeration,this paper puts forward collaborative planning measures through the example of Jiaxing in Zhejiang.It analyzes the necessity of rail transit development from the three levels of regioncity area-city,and puts forward that taking advantage of the development of intercity railway in metropolitan area to plan the construction of urban railway,promoting the integration of two networks of intercity railway in metropolitan area and urban(suburban) railway is the top priority,while building a low volume rail transit network with high-quality network in central urban area.Jiaxing's rail transit planning and layout focuses on regional coordination;interconnection,direct central connection,and scale control.It is planned to form a three main,two auxiliary,and five connected urban railway network and a grid radial modern tram network to support the development requirements of Jiaxing's external integration,cohesion,strength,and ecology.Through the analysis of examples,it hopes to provide references for other cities of the same type.
