基于快慢车组合的城市轨交走廊客流分析模型

Passenger Flow Analysis Model About Express/Slow Train in Urban Rail Transportation Corridor

摘要:

构建的客流分析模型由三部分组成，首先在随机用户均衡分配理论的基础上建立乘客路径选择模型，确定乘客选择路径的原则和客流分配的基本依据；其次，以轨道行程时间、车内拥挤度及平均候车时间作为影响乘客出行成本的主要因素建立乘客出行成本模型；再次，通过建立弹性需求模型，考虑乘客出行意愿与服务水平的相互影响.最后运用案例，对客流分析模型进行验证，并得出快慢线组合运营对轨道交通走廊运营效率的影响效用及相关结论.

Abstract:

The passenger flow analysis model is composed of three parts. First, based on the stochastic user equilibrium theory, a passenger path choice model was established to determine the passenger principle in path choice and the fundamental basis of traffic distribution in this corridor. Then, a passenger travel cost model was set up with the travel time, in vehicle crowding discomfort, waiting time as three major factors. Finally, an elastic demand model was built up to investigate the interaction between passenger travel intention and rail transit service level. A case study was made of the passenger flow analysis model, which verified the express/slow train operational efficiency in rail transportation corridor.
