北京新机场轨道交通与市区线网衔接规划方案分析

对城市轨道交通机场线规划设计方案影响显著的因素包括机场线的线路功能、发展模式及与市区线网的衔接模式。城市轨道交通机场线按其线路功能可分为城市轨道交通机场专线、混合线路及一般城市轨道交通线路。城市轨道交通机场线的典型发展模式有完全利用既有轨道交通线路模式,新建轨道交通线路模式及部分利用既有轨道交通线路模式。新建轨道交通机场线与市区线网衔接的典型模式为核心终止式、近端接入式及远端延展式。提出了城市轨道交通机场线与市区线网衔接规划方案的设计思路,并以此思路,从北京新机场航空客流分布情况、线路功能、发展模式和衔接模式4个角度分析了北京新机场轨道交通线路规划设计方案。

Integration Planning of Beijing New Airport Line and Urban Rail Transit Network

The functions,development mode and the connection with urban rail transit network are the main factors influencing Beijing New Airport Line planning,which consists of airport line,joint lines and normal urban rail line in terms of performance.The typical development mode of airport line is to use the existing rail line,build new rail line or partly use the existing line,and the newly built airport line will connect the urban rail network in core termination mode,near end access mode and far end extension.On this basis,the design concept of airport line and the scheme of its connection with urban rail network are put forward,the scheme is further analyzed from 4 aspects:the passenger flow distribution of Beijing new airport line,the line functions,the development mode and the connection mode.
