The invention belongs to the technical field of urban road traffic control, and relates to a variable guide lane real-time control method based on green light duration saturation. For a timing signal control intersection, a motor vehicle detector is arranged on each guide lane of an entrance road to which a variable guide lane belongs, and idle time length data is collected second by second. And estimating the expected green light duration of the motor vehicle phase by using the space-time duration data, and defining the ratio of the expected green light duration to the actual green light duration as the green light duration saturation. On the premise of not changing the signal timing of the intersection, the specified driving direction of the variable guide lane is automatically adjusted according to the green light duration saturation of the straight-going phase and the left-turning phase of the entrance road to which the variable guide lane belongs in a plurality of previous signal periods. According to the invention, the sustainable development of the phenomenon that the green light duration of one phase is seriously unsaturated and the green light duration of the other phase is oversaturated on the same entrance road can be effectively restrained.

    本发明属于城市道路交通控制技术领域,涉及一种基于绿灯时长饱和度的可变导向车道实时控制方法。本发明面向定时信号控制交叉口,在可变导向车道所属进口道路的每条导向车道上设置机动车检测器,逐秒采集空当时长数据。利用空当时长数据估计机动车相位的期望绿灯时长,将期望绿灯时长与实际绿灯时长的比值定义为绿灯时长饱和度。在不改变交叉口信号配时的前提下,根据可变导向车道所属进口道路的直行相位和左转相位在以往数个信号周期的绿灯时长饱和度,自动调整可变导向车道的规定行车方向。本发明能够有效遏制同一进口道路上一个相位绿灯时长严重不饱和、另一相位绿灯时长过饱和的现象持续发展。
