| 摘 要： | 以往轨道交通网络的规划主要依靠经验的、定性的方法 ,缺乏科学性 .为此 ,首先建立了轨道交通的阻抗函数 ,然后 ,基于均衡分配原理 ,建立城市轨道交通网络的客流量均衡分配模型 ,并采用Frank Wolfe算法求解了该模型 .该模型可以较真实地反映城市轨道交通网络上的客流量分配情况 ,提高目前轨道交通规划的科学性 .

| Abstract: | In the past,the planning of urban railway systems is based on experiential and qualitative methods.It lacks rationality.In this paper,a cost formula about urban railway system is established firstly; then a model based on equilibrium theory is proposed; finally an algorithm was addressed to resolve the model.This model can make the assignment of passenger flow in urban railway network more accurate.So it can make the planning method of urban railway system more rational. |

| Keywords: | urban railway network comfort of passengers cost formula equilibrium assignment |
