摘　　要：交通信号控制机(简称信号机),对减轻交警工作强度和维护交通安全畅通起着举足轻重的作用。为保证交通运行效率,信号机应采用多时段定时控制方式,同时应由单一方案单一路口控制转变成多方案多路口控制。为此,信号机应该在保证交通正常运行情况下,能够灵活配置和设定各种配时方案及配时库等信息。文中提出了一种基于DSP的交通信号控制机的实现方法,同时给出了具体的硬件、软件设计。The traffic signal controller is important for reducing the work intensity of traffic policemen and for increasing the traffic security of roadway. The multiple interval fixed-time control should be adopted to ensure the efficiency of traffic. At the same time, the multiple plan and multiple road control should be used instead of single control plan. So, the traffic signal controller should be flexible enough to control any roadway so as the traffic goes well. A kind of implementation of traffic signal controller based on DSP is suggested in this paper, and the detailed design of hardware and software is also introduced.
