城市商业区轨道交通与常规公交换乘协调评价研究

On coordination evaluation of urban rail transit and conventional public transit transfer in urban commercial area

基于城市商业区客流调查,总结商业区轨道交通与常规公交的交通特性;结合商业区用地布局特征,从换乘时间、换乘空间、换乘量、换乘舒适性、换乘安全性5个方面,创造性引入混合流修正系数、乘客留剩量、路径重叠系数等参数,建立轨道交通与常规公交换乘协调度测算模型。采取层次分析法确定5个指标的权重值,进行综合评价。通过西安小寨商业区换乘跟随调查数据,进行协调度实证计算。论文的研究成果为商业区交通换乘优化设计提供基础数据支撑和评价手段。

Based on the passenger flow survey of the urban commercial area,this paper summarizes the traffic characteristics of the rail transit and conventional public transit in the commercial area.Combined with the layout characteristics of commercial area,the coordination degree evaluation model between rail transit and conventional public transit transfer is established.The model includes five aspects,which respectively are the transfer time,the transfer space,the transfer quantity,the transfer comfort and the transfer security.And the model creatively introduces three indicators of mixed flow correction coefficient,passenger retention and the path overlap coefficient.The paper uses AHP to determine the weight value of these five evaluation indicators,and to make a comprehensive evaluation.The degree of coordination between rail transit and conventional public transit is conducted through the survey data from Xiaozhai commercial area in Xi'an.The research of this paper provides a basic data support and evaluation method for the optimization design of commercial traffic transfer.
