摘要
以城市交叉路口交通信号相位的优化为背景,分析了用圆染色解决这个问题的合理性,并给出现实中了几类交叉路口的最优相位个数。
The optimization of traffic signal phase at the intersection in a city is discussed. Waiting time is expected to be reduced by improving the repeating efficiency of traffic light. After circular coloring is proved to be the best tool to solve this problem, optimum phase numbers of some kinds of intersections are given. As a conclusion, this paper hopes to combine this method with intelligent control of traffic light for better settlement of traffic congestion.
