大规模动态交通网络路径选择模型分析

A Review of Rout Choice Models for Large Scale Dynamic Traffic Networks

从多方面分析了路段理想动态用户最优路径选择问题的变分不等式模型及求解算法的若干不适应性，论证了该模型并没有真正解决大规模化的问题。分析了理想动态用户最优（ＤＵＯ）选择条件所存在的问题；指出了流量传播约束条件中的错误与不适应性和变分不等式模型在大规模交通网络应用中的缺陷。

The shortcomings of the link based variational inequality model and the algorithm for ideal dynamic user optimal route choice problems are analyzed with an inclusion indicating the infeasibility of this model for solving the problems of large scale traffic networks. The drawbacks in ideal dynamic user optimal rout choice conditions and the errors in the flow propagation constraint conditions are reviewed in regard to many aspects.
