文章通过对目前国内外交通信号控制现状的分析，明确基于不同交通信息感知设备的自适应信号控制方法的优缺点，引出综合各检测器的特点并有明显优越性的微波检测器，通过虚拟检测线圈的设置，判断车辆离开和请求信号，在此基础上实现基于此检测器的自适应控制。并以合肥市高新区天湖路与科学大道交叉口为例，分析自适应控制前后的等待时间、延误、运行时间以及速度对比，阐明在未达到饱和状态的时间段自适应控制的优越性。

The paper explicated the advantages and disadvantages of adaptive signal control methods based on different traffic information sensing devices by analyzing the current situation of traffic signal control at intersection. Microwave Detector was proposed which is superior to other detectors and has comprehensive features of others. The adaptive control with microwave detector was realized through setting virtual detector loop and judging whether vehicles leave or need a request signal. An example was presented in Tianhu Road-Kexue Avenue intersection of Hefei. By the comparisons of indicators before and after adaptive control, such as waiting time, delay, travel time and speed, the results indicate the superiority of adaptive control before saturation state.
