中文摘要：
概述了动态最优交通分配的研究现状，详细描述了动态交通用户最优状态与变分不等式模型的等价关系．基于约束集合和行驶费用函数的描述，说明了变分不等式方法在动态最优交通分配中应用的必然．最后，分类综述了动态用户最优分配变分不等式模型及其代表性文献，讨论了当前存在的几个主要问题及进一步的发展展望．
英文摘要：
This paper summarizes the researches on dynamic traffic assigmnent problems. The equivalent relation between the variational inequality model and the dynamic user-optimal condition is described. The necessity of the application of variational inequality method to dynamic traffic assignment is explained based on the description of the set of constraints and travel cost function. An overview of the current works in the dynamic traffic assigmnent using variational inequality method is presented. Existing problems and further researches of the variational inequality dynamic traffic assigmnent models are discussed.
