摘　　要：在单路口感应控制系统中,单位绿灯延时对于感应信号控制的效率起决定性的作用,合理的单位绿灯延时可以消除为等待少数车辆而浪费的绿灯时间,使绿灯延时高效运行,从而可提高通行能力,降低延误,减少车辆追尾等交通事故的发生.比较了两种单位绿灯延时模型,并通过仿真分析给出对于感应控制系统比较有用的结论.For actuated-control system at isolated intersection, the extension green time plays a crucial role in the efficien- cy of actuated signal control. A suitable extension green time can eliminate the wasteful green time just because of waiting for a few vehicles and make itself perform efficiently, thus improving the traffic capacity, reducing delays and traffic accidents such as rear-end accidents. The paper makes some useful conclusions by comparing two kinds of the extension green time models through simulation.
