摘　　要：现代生活中上下班高峰期交通是否堵塞是人们关心的问题,十字路口交通信号灯控制系统是否正常运行是非常重要的。针对交通信号灯设计要求力求结构简单,合理选择电子元器件,通过对东西南北两组红、绿、黄交通灯的控制,完成道路上的车辆交替通行,用数码显示车辆通行的倒计时时间,利用计算机仿真软件对电路性能指标进行仿真和优化研究,将选择好的元器件以模块化的形式合理布局安装、焊接在实验板上,通过对控制系统的静态和动态的不断调试与改进,实现了对交通灯的控制,确保车辆安全有序地通行。Traffic jam in rush hours is one of the major concerns of people in modern llfe, thus it is critical for the intersection traffic signal to operate properly. Based on the requirement of the traffic lights, the design should be simple in structure, and the choice of electronic components should be reasonable. Through the control of the two groups of red, green, and yellow traffic lights in east, west and north, south, the vehicles will be guided to pass alternately. A digital display is used to show the traffic countdown. Computer simulation is used to study and optimize the performance of the circuits. The chosen components are arranged properly in modules, and soldered on the experiment board. Through the static and dynamic debugging of the control system, realizing the control of the traffic lights, and guarantee the safety and ordered passing of vehicles.
