The invention discloses an intersection flow density induction control method. A detector arranged at an intersection of a road, a bridge and a tunnel is included; the detector collects whether a vehicle arrives at the intersection or not and the arrival time of the vehicle, and sends out the collected data in batches; the real-time change of the traffic flow is obtained according to the data collected by the detector, and the signal phase timing is adjusted by adjusting the variable initial green light time length gi, ci and the prolonged green light time length gi, yi; at the phase initial moment, the minimum green light time length gimin is set, the initial green light time length gi is changed, and ci is larger than the minimum green light time length gimin; the green light time duration of the green light stage of the intersection is calculated according to the data acquired by the detector during the crossed yellow light and red light periods, wherein the green light time lengthgi is the sum of the variable initial green light time length gi, ci and the prolonged green light time length gi, yi. According to the invention, the effective utilization rate of the green light duration is improved and the delay is reduced through the initial green light duration suitable for traffic requirements and the dynamically changing green light prolonging control mode.

    本发明公开了交叉口流量密度感应控制方法,包括设置于路桥隧的交叉口的检测器;检测器采集交叉口是否有车辆到达,以及车辆的到达时间,并将采集到的数据分批发出;根据检测器采集到的数据获得交通流的实时变化,通过调整可变初始绿灯时间长度g和延长绿灯时间长度g,调整信号相位配时;在相位初始时刻,设定最小绿灯时间长度g,可变初始绿灯时间长度g>最小绿灯时间长度g;根据检测器在所述交叉的黄灯和红灯期间采集到的数据计算交叉口绿灯阶段绿灯时间长度;绿灯时间长度g是可变初始绿灯时间长度g加上延长绿灯时间长度g。本发明通过适合交通需求的初始绿灯时长和动态变化的延长绿控制方式,提高了绿灯时长的有效利用率,降低延误。
