The whole idea is to use the smallest STC89C52 SCM system as a control part, control the digital tube to display the allow passage remaining time or the no thoroughfare remaining time. Simultaneously with the light-emitting diode displays the status of each intersection traffic. Button to make the whole system work by the three working state, night mode state, the state of the forbidden line mode and normal traffic patterns state. The design incorporates a variety of control techniques by comparing the different programs, analysis, determined using STC89C52 microcontroller overall design of the controller. The systems hardware modules include: STC89C52 SCM minimum system module, key circuit module, the digital display circuit module and a light emitting diode circuit module. According to the hardware design of the preparation of the corresponding software modules. Software modules include: system initialization module, boot LOGO module, data processing module, key scan module, LED display module, LED light module. The specific design of the system is completed the city simulation and control of traffic lights, traffic lights to reproduce the actual city of workflows. The design of the hardware circuit is simple, software development, easy to understand, easy to modify. On the basis of the traditional traffic light on the increase in night mode, the forbidden line mode enables traffic light
