摘要
分岔是引起交通流中各种非线性行为的主要原因之一,本文对当前交通流中分岔现象的的研究情况进行了综述,介绍了交通流模型中分岔的存在性分析以及引发交通流相变的基本机理,并对该领域以后工作的开展做了讨论。
The nonlinear behaviours in the traffic flow have rich relations with the bifurcation phenomena. In this paper, a review of study on bifurcation in traffic flow models was provided, especially the analyses on the presence of the bifurcation and the mechanism of phase transition were introduced ,and finally the discussion was made for the future work in this field.
