摘　　要：针对城市地铁网络动态客流分配模型构建问题,提出了基于时刻表的地铁时空扩展网络构建方法.首先对地铁网络客流动态特征进行分析,在此基础上构建了基于物理站点和区间的地铁空间网络.结合列车运行时刻表,对物理站点进行时间扩展,定义了基于时刻表的地铁空间扩展网络.最后对物理节点以及物理弧进行扩展,构建了基于时刻表的地铁时空扩展网络,并对网络中的基本元素进行了定义.基于时刻表的地铁时空扩展网络的构建方法,将复杂的地铁客流动态分配问题采用经典的静态用户平衡模型来进行描述,可为城市地铁网络动态客流分配研究提供参考.Focusing on the dynamic passenger flow assignment for urban subway network, this paper proposes a method to build the space-time extended network for urban subway system based on the schedule information. First, the dynamic characteristics of network flow are analyzed and the definition of the spatial structure for subway network is proposed based on the physical site and interval. Then, this paper presents the space-time extended network as well as the concept of space-time path, by combining the train schedule information. Then, this paper proposes a method to build the space-time extended network for urban subway system with the schedule information. The definition and description of the basic elements in such network are also provided. The proposed methodology provides a way to use classic static user equilibrium model to describe the complex dynamic flow assignment, which can serve as reference for dynamic flow assignment for urban subway network.
