轨道交通一般站点换乘交通组织特征聚类分析

随着轨道交通线网的大规模建设，轨道交通站点急剧增多，站点换乘成为影响公共交通出行的关键因素．目前，在轨道站点与其“两端”的交通方式衔接过程中，存在换乘设施不足、换乘时间长、无秩序、不方便等状况．因此分析轨道站点周边换乘交通组织特征，解决“最后一公里”问题，是促进出行方式调整的重要一环．采用SAS对北京市核心区内一般站点的换乘现状属性进行分类，然后结合现场调研对每类站点再分级，归纳出每级站点的换乘交通组织特征．最后得到站点不同类型特征，并用于挑选深入研究的典型站点，旨在为轨道交通一般站点周边换乘设施规划、布局、换乘交通组织优化提供参考．

Transfer Traffic Organization Characteristics of General Rail Transit Site Based on Clustering Analysis

With the large-scale construction of rail transit network,rail transit sites increase rapidly,and site transfer becomes the key factors influencing the public transportation. So far,in the process of traffic modes transfer between site and trip end,there are problems like transfer facilities deficiencies,long walk for transfer,out of order,not convenient etc. Therefore,it is very important to solve ＂the last kilometer＂problem. Taking the core area of Beijing as an example,transfer situation attributes of general sites at present were classified. Then combined with field investigation,each type of station was graded again,and transfer traffic organization characteristic of each level general site was concluded. Finally,the different types of characteristics of the site are got,and that is used to choose typical sites of further study. It will supply reference for general rail transit site surrounding transfer facilities planning,layout,and transfer traffic organization optimization.
