轨道交通无障碍换乘模式下的客流分配

Passenger flow distribution in rail transit no-barrier transfer mode

轨道交通线路上的途径客流是线路客流的重要组成部分,将无障碍换乘客流准确地分配到各途经线路可以给后续各项客流分析提供数据支持。参照公交线路起点—终点(OD)反推技术,把吸引权系数法引入轨道交通无障碍换乘模式下的线路客流分配中,根据不同线路的进出站客流数据定义吸引权系数,加权客流换乘次数和途径站点数,建立轨道交通无障碍换乘模式下的一种客流分配模型。实例验证表明,在应用此模型时,考虑客流高峰区间,合并不同时段区间下的计算结果,可以得到更好的精度。

Passing-by passenger flow is the basis of rail transit passenger analysis.Based on the bus Origin-Destination（OD） matrix estimation model,attraction weight coefficient method was introduced into passenger flow research in rail transit no-barrier transfer mode.Using passenger entry and exit data from Automatic Fare Collection（AFC） system as input,a new passenger flow analysis model was presented.Passengers transfer times and passing-by stations（distance factor） were considered in this passenger distribution method.The case indicates that it can increase the accuracy to consider the range of passenger flow peak.
