| 摘 要： | 建立周期性边界条件下的十字交叉路口元胞自动机混合交通流模型,增设左转绿灯,而且规定转弯车的最大数量,研究配时问题、主道初始密度以及混合比例系数对交通流的影响。结果发现,配时问题对交通流的影响较大,合理配置红绿灯时间可以改善交通,增设左转绿灯可以达到缓解拥堵,提高道路利用率。

| Abstract: | A model for mixed traffic flow of a single intersection with periodic boundary conditions is established.The model investigates the effect to traffic flow under different parameters such as time distribution,the initial density of main road and the proportion of mixture coefficient etc.by considering the situation of setting turn-left green light and the maximum number of turning vehicle.The results show that the effect of time distribution is greater to traffic flow.The traffic would be improved if the tra... |
