摘　　要：在使用低频压力检测卡实时采集交通路口各方向车流量数据的基础上,提出了一套自动交通灯比例时长智能交通控制方案,即根据车流量的实际情况,自动调节信号周期和红绿灯配时比例,以尽量减少道路交通路口的车辆滞留,实现交通灯的智能化控制;系统采用ZigBee和RFID相结合的无线控制技术,详细论述了系统的组网构成和四个单元主节点路口控制器的硬件与软件设计,并对其中的关键技术进行了阐述。为解决路口拥堵、提高通行效率提供了一种有效的思路和方法。On the basis of real - time traffic volume data from low- frequency pressure detecting cards, the paper proposed an intelligent traffic control system scheme for automatic adjusting the time length of traffic lights. The designed control system could adjust the signal cycles and the time length ratio of traffic lights auto- matically based on real - time traffic volume, so that vehicles held up at traffic crossing could be reduced and the intelligent control for traffic lights could be realized. The designed control system used wireless control technique combining ZigBee with RFDI. In this paper, the networking configuration of the designed system and hardware and software design for traffic crossing controllers as well as some critical techniques among the designed system were described concretely. The designed traffic control system scheme provided an effective method for resolving the problems of traffic congestion and improving traffic efficiency.
