摘　　要：针对目前十字路口交通灯定时分配运行方式,存在着交通指挥盲点和各相位车流不同而通行时间相同的问题,提出了一种以实时检测车密度的大小和实时交通灯的状态共同来实现交通灯对交通状况的实时指挥.使用单片机单片机AT89C51完成对检测数据信号的处理.现实实时交通指挥灯的系统设计,以改善十字路口交通状况.There are some problems in the timing distribution and operation mode of the crossroads traffic lights, such as some blind spots in traffic guidance, and different traffic streams with simultaneous passage time in each phase. A real time traffic guidance of traffic lights to traffic states which is accomplished between real time guage of traffic density and real time traffic states is designed in this paper as a solution to the above traffic problems. Singlechip AT89C51 is used for the dealing of detected signals. This real time traffic lights system design aims to improve intersection traffic conditions.
