摘要 [目的]推动轨道交通四网融合发展是我国推进以都市圈为主要空间载体的新型城镇化的迫切需求,因此有必要研究轨道交通四网融合规划关键问题。[方法]基于轨道交通技术经济属性和四网融合核心目标,提出四网融合规划的概念;在系统梳理都市圈范围界定的基础上,从轨道交通的维度明确了四网融合规划的范围;根据各层次轨道交通的功能目标和客流需求特征,明确了四网融合的主要形式;从网络、线路、节点三个层面结合实际案例提出四网融合的基本方法和技术要点。[结果及结论]轨道交通四网融合规划是契合城市及交通发展阶段所做的科学的建设实施安排。四网融合规划的范围是都市圈范围内建成区连片开发,且交往联系相互渗透的核心区域,一般是都市圈中心城市半径30~40 km的空间尺度。四网融合的形式主要有互补融合和代偿融合两种类型。对于融合技术方法,网络层面以功能为导向,线路层面以通道为重点,节点层面以枢纽为抓手。 [Objective]Advancing urban rail transit four networks(mainline railways,intercity railways,suburban railways,and urban rail transit)integration is an urgent need for China to promote new urbanization with metropolitan areas as the main spatial carrier.Therefore,it is necessary to study the key issues in planning for the integration of four networks.[Method]Based on the technological and economic attributes of urban rail transit and the core objectives of network integration,the concept of four-network integration planning is proposed.The scope of the integration planning is defined from the dimension of urban rail transit on the basis of a systematic metropolitan area scope sorting.The primary forms of four-network integration are clarified according to the functional means and passenger flow characteristics of various levels of urban rail transit.The basic methods and technical points for four-network integration are presented at three levels:network,line,and node,with practical case studies.[Result&Conclusion]The planning for the four-network integration is a scientifically sound implementation arrangement aligned with the stages of urban and transport development.The scope of four-network integration planning typically covers contiguous developed areas within metropolitan regions,with core areas of mutual connectivity and permeability generally within a 30 to 40 km radius spatial coverage from metropolitan area central city.The main forms of four-network integration are complementary integration and compensatory integration.Regarding the integration techniques,the network levels focus on functionalities,the line levels emphasize corridors,and the node levels target hubs.
