Abstract: This paper sets up a logarithm multi routes choice model of transport passage system predicating on the maximum of system utility and puts up the demarcating method of its parameter and its numerical solution.Then it gives an example.This model can forecast the ration of traffic distribution on each route in a network.It can also be used to analyse influence of service attribution on road users' choice of routes.

Key words: route choice model, network distribution, utility function, service attribution, generalized travel cost

摘要： 笔者在系统效用最大化前提下,建立了交通运输通道系统多项式分对数多路线选择模型,提出了模型中参数的标定方法和模型的数值解法,并结合实例对模型进行了标定.利用所建立的模型可预测路网交通量在多条路线上的分配比率,并可利用弹性定义分析不同服务属性对出行者选择路线的影响.
