基于换乘网络的城市轨道交通客流分配模型

摘要

In the study of passenger flow distribution in urban rail transit,the impact of the transfer schemes shall be consid-ered. To visually express the transfer schemes and calculate the traffic impedance,a construction method of transfer net-work for urban rail transit is proposed. Based on an analysis of the network arc impedance calculation,a model of equilibrium passenger flow distribution is established,which has the same form as the road traffic assignment model,and can be solved by traffic flow assignment algorithm. Finally,the effectiveness of the method is verified by numerous experiments on practi-cal cases.%城市轨道交通客流分配需要考虑乘客换乘的影响.为了直观表达乘客的换乘方案,方便换乘阻抗的计算,阐述了城市轨道交通换乘网络的构建方法,在分析换乘网络弧的阻抗计算方法的基础上,建立了城市轨道交通客流均衡分配模型.分析说明了该模型与公路交通分配模型具有相同的形式,因此可利用公路交通流分配算法进行求解.最后,通过实例验证了的该客流分配方法的有效性.
