The invention discloses a traffic signal lamp intelligent allocation method based on a traffic sensing signal control chart. The method comprises the following steps: converting collected traffic volumes of vehicles of various models into equivalent car traffic volumes; establishing a Greilz linear model, and obtaining a relationship between the speed before entering the intersection entrance lane and the green light passing speed of the intersection entrance lane; according to the average time headway of vehicles on the main road at the intersection, the distance between a pressure sensor and a stop line and the number of vehicles parked between a detector and the stop line, the initial green light time is obtained; combining the total width of a motor vehicle road, the distance between the pressure sensor and the stop line and the speed of the intersection to obtain unit green light prolonging time; obtaining the shortest green light time by combining the initial green light time and the unit green light prolonging time; and drawing an induction signal control chart in combination with the unit green light prolonging time so as to obtain the main path induction signal control duration. According to the invention, vehicle parking delay is effectively reduced, urban traffic jam is relieved, and travel efficiency is improved.
本发明公开了一种基于交通感应信号控制图的交通信号灯智能调配方法,将采集的各型号车各自驶入的交通量换算成当量小汽车交通量;建立格林希尔兹线性模型,得出进入交叉口进口道前的速度与交叉口进口道绿灯通行速度之间的关系;根据交叉口主路车辆的平均车头时距和压力传感器距离停止线的距离,检测器与停车线之间可停放的车辆数,得到初期绿灯时间;结合机动车道路总宽、压力传感器距离停止线的距离及交叉口的速度,得出单位绿灯延长时间;结合初期绿灯时间和单位绿灯延长时间,得到最短绿灯时间;结合单位绿灯延长时间,绘制感应信号控制图,从而得到主路感应信号控制的时长。本发明有效地减少车辆停车延误、缓解了城市交通堵塞、提升出行效率。
