摘　　要：本研究以动态交通分配模型为基础,研究潮汐车道的适用范围和方案选择。对潮汐性拥堵和潮汐车道的性质进行了定性分析之后,在动态交通分配的程序中,通过仿真的方法,测试了潮汐车道对于路网的改善效果,并且着重研究了交通需求的分布特性变化时,潮汐车道的表现,该部分主要采用了情景分析的方法予以分析。最后,本研究给出了一套完整判断潮汐车道是否必要以及如何给定潮汐车道方案的方法。Based on dynamic traffic assignment （DTA） model, this project focuses on the practical extent of reversible lanes and how to choose a suitable scheme of it. Firstly a qualitative analysis on the characteristics of tidal demand distribution and the main properties of reversible lanes is presented. After that, the DTA model, which is coded as a program, is used to test how the network become better after the operation of reversible lanes. Then this project focuses on how the performance changes as the tidal demand distribution change, through which we find some characteristics that have big effects on performance. The method of scenario analysis is used in this stage. Finally, based on above jobs, the project gives a complete guide on deciding whether to use a reversible lane strategy and how to decide the details of it.
