摘　　要：将城市轨道交通路网抽象为由若干车站、上下行区间及其运输能力、OD对路径及其客流量和权重等构成的动态有向加权路网模型,用以表达路网中乘客出行行为、列车运行图和客流的关系;在此基础上,通过分析OD对有效路径、区间和路径的剩余运输能力,以满足乘客出行为目标,建立城市轨道交通路网连通可靠度评估模型。以北京城市轨道交通为例,运用该模型进行城市轨道交通路网连通可靠度评估的实证分析。结果表明:在城市轨道交通路网中,虽然部分车站在物理上有线路连通,但由于受乘客出行行为、列车运行图和客流等的影响,在有些时间段这些车站在运输功能上不是连通的,从而使得路网的整体连通可靠度降低。In this paper, urban rail transit network is abstracted as a dynamic and directed-weighted net- work model which is composed of stations, intervals of up and down direction, transport capacity, OD paths, passenger flow and weights, in order to express the relationship between passenger behavior, train working diagram and passenger flow. Based on this, through analyzing the effective OD paths and the re- sidual transport capacity of interval and path, a connectivity reliability model of urban rail transit network is established with the goal of meeting passenger OD. The feasibility and rationality of the proposed method is verified through analyzing the connectivity reliability of Beijing urban rail transit. The results show that, although some stations are connected physically, due to the impact of passenger travel behavior, train working diagram and passenger flow, the stations are not connected functionally during certain times which results in the lower connectivity of urban rail transit network as a whole.
