摘　　要：动态用户最优交通分配理论作为智能运输系统的重要理论之一,采用变分不等式模型来解决分配问题日益成为国际上的研究热点。就此问题的发展过程进行了综述性研究,并探讨了动态用户交通分配理论的发展方向;概述了动态用户最优交通分配的研究现状,详细描述了变分不等式模型与动态交通用户最优状态的条件互等关系。基于用户最优限制条件的描述和动态用户交通分配模型的表达,说明了变分不等式方法在动态用户最优交通分配中应用的必然。同时,对动态用户最优分配的变分不等式模型如何应用,当前存在的几个主要问题及进一步的展望进行了讨论。Dynamic user optimal traffic assignment theory as one of the important theories in intelligent transportation system, using the variational inequality model to solve the assignment problem has increasingly become the focus of international research. The article development process review, and explores the dynamic user traffic assignment theory direction of development. Overview of dynamic user optimal assignment,and a detailed description of the variational inequality model and the dynamic traffic user optimal condition reciprocal relation. Based on user optimal constraint conditions is described and the dynamic user traffic assignment model expression. The variational inequality method in dynamic user optimal assignment the necessity of the application of. At the same time, through variational inequality of the dynamic user-optimal assignment model of how to apply, several major issues that currently exist and further developments were discussed.
