摘要
对SUE问题中几种常用的路线选择模型进行了分类研究,重点介绍了它们各自的理论基础并比较了其差异,且通过多个算例分析了它们各自的表现效果.结果表明,同一网络中各个模型的表现效果不一定相同,不同网络中同一模型的表现效果也有所差异.这一研究对交通配流中的路线选择问题具有重要的指导意义,表明现有研究中常出现的通过单个选择模型或单个网络得出的结论并不一定可靠,应该根据模型和网络的特点谨慎选择.
This paper classified and researched several route choice models, which are commonly used in SUE problem. It centered on their basic theories and compared the differences. Through several examples, it analyzed their representations. The resuh indicates that each model may have different representation in the same network and the same model may have different representation in different networks. The research is very important to route choice used in traffic assignment problems, which indicates that the conclusion in the existing researches derived from only one model or network may be not reliable. It should be chose cautiously according to the characteristics of models and networks.
