摘　　要：出行车辆的最优路径是随着时间和路况的变化而变化的,为了研究出行车辆的动态路径选择行为,基于有交通信号控制的交叉口,利用有向图理论,建立城市交通网络路径的优化模型,用传统dijkstra算法进行优化,动态获得出行车辆的最优路径。最后引入简单实例说明研究的方法,计算机仿真结果表明该方法是可行、有效的。As the time and the state of the road are changing, the optimal route of the going vehicle is also changing, based on road intersection with command signal. In this paper the optimal model of the urban traffic network is built by the use of the digraph theory. We optimize the model using the dijkstra algorithm and obtain the optimal route of the going vehicle dynamically. The computer simulation shows the effectiveness of this method.
