摘要
通过引入图论中“圆染色”的概念,将城市路口交通信号灯最优相位个数归结为其交通流模型图的圆色数.根据常见简单五交叉路口交通状况,由车流的冲突关系给出交通流模型图并确定这些图的圆色数.
In this paper, we concentrate on the optimization of traffic signal phase of simple five intersection in city. We hope to reduce the waiting time by improving the circle efficiency of traffic light. Circular coloring is proved to be the best tool to solve this problem.
