利用实时交通流密度参数,应用图论相关理论和Kruskal算法,分析了交通流阻塞区、过渡区及常态区的动态演化过程,可为城市道路偶发性拥堵疏散控制策略的选取提供依据。利用Matlab进行了数值仿真,分析结果表明了该方法可行。

In order to quickly determine the traffic control strategies of urban road congestion,a dynamic analysis method of the congestion region was put forward based on the traffic flow parameters,graph theory and Kruskal calculation method,and the results of traffic state morphing of blocking region,transition region and normal region were proposed.By the numerical simulation with MATLAB,the results show that this dynamic analysis method was feasible ...
