基于随机网络加载的城市轨道交通客流分配模型
|
摘要
在选择适合于研究城市轨道交通客流分配模型的基础上,考虑影响城市轨道交通乘客出行路径选择行为的因素,介绍了乘客出行阻抗的计算方法,以及网络随机加载模型的概念和相关算法。以上海市轨道交通为算例,在实际线网中选择某一固定起讫点,对各可选路径进行客流分配计算,结果与实际情况相符。这一算例验证了改进Logit模型运用于城市轨道交通客流分配的合理性和可实施性。
Based on the selection of suitable urban rail traffic assignment model,and considering the factors that directly influence the trip route choice behavior of passengers,a comprehensive analysis and calculation of travel impedance,the concept of stochastic network loading model and related calculations are introduced. By taking Shanghai rail transit as an example,a fixed start and end point in practical network is selected,where the passenger flow distribution in alternative pathes is calculated,and the calculation result is consistent with the actual situation. So,this study verifies that the improved Logit model is reasonable and executable for passenger flow distribution of urban rail transit.
