摘　　要：针对交通饱和期间车辆滞留的问题,提出了一种信号机单点自适应控制的配时方法。考虑到道路车辆密度、流量检测方法等因素对交通流量的影响,改进了交通流量检测方法,并对实时检测的交通流量进行补偿修正,同时结合F-B配时方法,对周期时长和绿信时间进行优化,从而加快滞留车辆的消散速度,有效地缓解车辆滞留情况。As for the retention problem of stranded vehicles during the traffic saturation,a method of self-adaptive signal-timing control for a single intersection is proposed to reduce the vehicle-retention and improve the intersection utilization efficiency.Considering the influence of vehicle density and traffic flow detection method on the traffic flow,the method of traffic flow detection was improved,the magnitude of traffic flow obtained by real-time detection was compensated,and the cycle time length and green time were optimized in combination with the F-B time allocation method.With the method,the dissipation speed of stranded vehicles is accelerated and the vehicle-retention is reduced.
