基于层次分析法的城际轨道交通构架研究

交通运输系统是一个由相互关联、相互制约的众多因素构成的复杂而又缺少较多定量数据的系统,城际轨道交通是交通运输系统的重要组成部分,其线网构架受众多因素制约,应按层次结构逐步研究,最后确定客流主通道,从而建立较为合理的构架方案。结合京津冀城市群城际轨道交通系统研究实践,基于层次分析法,对交通网构架方案研究方法进行分析和总结,提出建立交通线网构架方案应从交通节点、城市经济引力、区域交通区位线、通道类别和层次以及区域空间布局等五个主要方面着手,并提出了研究方法的主要要点。

Study of Intercity Rail Transit Architecture Based on Analytic Hierarchy Process

The transportation system is a complex system,restricted by the lack of more quantitative data,and constituted by numerous factors which are interrelated and conditioned with each other.In turn,the intercity rail transit is an important part of the transportation system;its line network architecture is restricted by many factors,and should be gradually researched according to hierarchical architecture,so as to finally determine the main pasenger-flow channel;and as a result,a more reasonable architecture scheme can be established.Combining the research on the intercity rail transit system of the Beijing-Tianjin-Hebei city group,based on the analytic hierarchy process,analyzing and summarizing the research methods of architecture scheme of traffic network,the paper draws conclusion that for the establishment of transit network architecture scheme,the five main aspects should be paid attention to: the transit juncture,city economic attraction,regional traffic location,channel type and hierarchy,and the regional spatial layout.The paper also puts forward the key points of research methods.
