摘　　要：首先提出一个简化的交叉路口交通流模型,然后从系统的角度提出了一种区别于传统信号协调控制的新算法。模仿交警指挥时的判断决策过程,设计了一种基于相序优化的模糊控制器。进行交通控制时,采用模糊控制器和相序优化器联合控耕。前者用来决定改变当前绿灯相位时刻,后者从相序中根据优先权的大小决定下一个放行相位。仿真研究表明,控制效果良好。A simplified traffic flow model for the road intersection was proposed and a fuzzy logic controller based on the phase sequencer was developed. The developed controller was designed based on the simulation of the traffic policemen judging and decision-making process during their manual traffic control. A new algorithm was used which is derived from the system concept and differs from the traditional signal coordinated control algorithm. The fuzzy controller and the phase sequencer are combined to perform the traffic control, the former decides the desirability of phase switch, and the latter decides the next green phase based on the priority rating. The computer simulation showed that the developed controller works with good performances.
