摘要:: 文中主要针对步行街交通的特殊情况，设计了一款步行街自助式的交通控制器。系统除了可以完成常规交通指挥的功能外，还可以针对步行街的行人主体需要，在主干道没有车辆的情况下，行人可以通过按控制按钮使十字路口的红灯变为绿灯，及时过马路，而不用等红灯变绿灯，节省了等待时间；当步行街无人过马路时，则主干道将持续绿灯，保证主干道车辆通行。系统设计应用EDA的设计方法，采用 Quartus软件进行了电路仿真和调试，基本满足设计要求，具有实用性、实时性、易操作、人性化、造价低等特点。

Abstract:: Aiming at the special circumstances of the pedestrian traffic,a traffic controller of pedestrian street self-service is designed. The system can complete the function of the conventional traffic control,the person can also press the control button to change the red light to green light in accordance with the need of body in pedestrian street in the absence of vehicles,crossing the road in time,instead of waiting a red light changing a green light,saving the waiting time. When none of the pedestrian street crossing the road,the road will continue to be a green light,which guarantees the road traffic. System design applies the method of EDA,using the Quartus software for circuit simu-lation and debugging,meeting the design requirements basically,which is practical,real-time,low cost,easy operation and humanization and so on.
