The invention provides a main line green wave vehicle-road cooperative control strategy based on straight-going priority, and the strategy comprises the steps: collecting the left and right turning afflux amount of an upstream intersection and the straight-going retention amount of the current intersection in the previous period through roadside equipment, and calculating the phase difference advance time and phase difference of two adjacent intersections, so as to reduce the travel time of a straight-going traffic flow; the method comprises the following steps: acquiring vehicle arrival data of a green wave straight phase during a green light period through roadside equipment, and then calculating green light prolonging time of the green wave straight phase so as to reduce the vehicle retention amount of a straight traffic flow; and finally, vehicle speed guidance is carried out through roadside equipment, edge computing equipment, OBU equipment and roadside display equipment, so that each steering traffic flow is promoted to keep vehicle team marshalling, and the waste of straight green light time caused by phase transition is reduced.
本发明提出一种基于直行优先的干线绿波车路协同控制策略,通过路侧设备采集上游交叉口的左右转汇入量及当前交叉口前一周期的直行滞留量,计算相邻两交叉口的相位差提前时间和相位差,以减少直行车流的行程时间;通过路侧设备采集绿波直行相位绿灯期间的车辆到达数据,再计算绿波直行相位的绿灯延长时间,以减少直行车流的车辆滞留量;最后通过路侧设备、边缘计算设备、OBU设备及路侧显示设备进行车速引导,促进各转向车流保持车队编组,以减少相位过渡造成的直行绿灯时间浪费。
