一种公交网络客流分配方法及其实用性研究

在现有公交客流分配方法的基础上,提出了完整的公交网络设计概念,并给出了公交网络的表示方法。根据公交线路特性,分析了换乘、发车频率、票价对客流分配的影响,将其考虑到公交网络的属性中,给出了网络中各种阻抗的计算方法。然后根据Log it模型提出公交网络客流分配方法和指标计算方法,并对此设计了实例进行计算和分析,其过程显示公交线网的特征,结果符合实际情况,计算速度也较快。提出的分配方法适用于公交客流分配,同时可以用于大型网络计算,扩展了公交规划算法的理论。

An assignment method for transit network and its practical application

A complete conception of transit network was proposed with its detailed design according to some existed transit assignment methods. Then the transit characteristics were considered in transit networks based on the effects of transit transfer, headway, and price. Further, all transit arc costs in designed transit networks can be calculated exactly. A transit assignment method is developed based on Logit Model with calculation formulation of relevant indexes. Sample results describe the transit networks characteristics within a reasonable calculational time. This method is applicable to transit assignment for large transit networks as an extension of traditional transit planning algorithms.
