摘　　要：城市交通拥堵已成为当今大中城市交通的普遍问题,如何在现有道路的情况下,采用现代化技术优化交通运行、改善拥堵现象,是本文探讨的问题。该系统根据地感线圈测试实时车流量,确定放行时间,完成整个自适应过程,实现了交通灯有效控制;各相位之间的转换能随着交通流的不同而自适应地变化,均衡路网内交通流运行,充分发挥道路系统的交通效益;选用无线网络技术传输信号减少了强电驱动的走线长度,减少了施工量。在实际路口进行自适应系统性能测试表明,该系统能根据十字路口相距中的动态车流量优化信号灯的指挥时间,能有效改善拥堵现象。Urban traffic congestion has become a common problem in today＇s large -and medi- um-sized city traffic. The system uses the circular coil test real-time traffic flow to determine the release time to complete the adaptive process. The system realizes the effective control of the traffic lights, and each phase can adaptively change with the type of traffic flow; Wireless tech- nology eliminates the trace length of strong electric driven trace and reduces the amount of con- struction. The signal timing plans were optimized by measuring the dynamic traffic on the orossroads, and the results show that this method effectively solved the congestion phenomenon.
