提出了一种基于模糊控制器的干线控制算法，该算法有两个模糊控制器：绿灯延长时间模糊控制器和相位决定模糊控制器。前者决定当前绿灯相位的结束时刻，后者根据各相位的紧急度值的大小决定下一个放行的相位。运用仿真技术，把该控制方法和传统的定时控制方法进行了比较。仿真结果表明，本文提出的控制器是有效可行的，且效果优于定时控制。关键词：干线；模糊控制器；相位；紧急度值；仿真技术Abstract： An urban traffic algorithm of the trunk road based on fuzzy control is proposed, which has two fuzzy controllers, the one that extends the time of green light and the other that determines which phase will be the next green phase time. The former determines the end time of the current green phase, and the latter determines which one will be the next phase according to the emergency value. Both methods of fuzzy control and the traditional control of time-fixed are compared applying simulation technology. The simulation shows that the algorithm is realizable, and is better than the time-fixed method.Key words: trunk road; fuzzy controller; phase; emergency value; simulation technology
