| 摘 要： | Logit是一种重要的随机网络配流模型,常用于市域、省域的交通分配预测.但该模型的Stoch算法在确定"合理路径"的关键步骤时存在漏洞,明显存在交通分配结果不合理问题.文中通过比较以往各种合理路径的算法,提出了一种既合理,又经济的算法.解决了Stoch算法中对合理路径定义不合理的问题,使得分配结果更合理,通过建立相关路网的实例检验,取得较好的效果.

| Abstract: | The Logit-based loading model is an important stochastic network loading model,which is widely used in the traffic assignment of city-level and province-level.But there is a bug in the step of "reasonable path" in Stoch algorithm of the model,which may lead to many improper results in traffic assignment.This paper made a suitable and convenient algorithm by making comparison of many earlier reasonable path algorithms,which solved the problem of improper definition of reasonable path in Stoch algorithm and m... |
