The invention relates to a dynamic shift left-turn intersection cooperative control system and a vehicle speed guiding method. The method comprises the steps that the states of all vehicles arriving at an intersection within a set time period, the number of left-turn, straight-going and right-turn vehicles in the direction of each entrance, and vehicle speed and position information are acquired; judging whether the switching condition of the channelization type of the shift left-turn intersection is met or not according to the lane width, the intersection flow and the shape of each entrance of the current intersection; determining the steering request of the vehicle and the number of vehicles in the corresponding direction, and obtaining the lane width, lane function and lane number of the corresponding short time period according to the vehicle type; converting the number of vehicles arriving in the straight and left turning directions of each entrance within a set time period into hour flow and saturation flow of each lane, and determining critical maximum lane flow; determining whether the left-turn vehicle changes a lane to a shift left-turn lane or not according to the acquired information, and determining safe lane changing speed guidance of the vehicle; and determining the maximum and minimum acceleration and deceleration of the vehicle, judging the vehicle and lamp control state, and guiding the vehicle to execute speed guidance.

    本发明涉及一种动态移位左转的交叉口协同控制系统及车速引导方法,包括获取设定时间段内所有车辆到达交叉口的状态,各进口方向左转、直行和右转车辆数目、车速与位置信息;根据当前交叉口各进口的车道宽度、交叉口流量和形状,判断是否满足移位左转交叉口渠化类型的切换条件;确定车辆的转向请求及对应方向的车辆数,根据车辆类型得到对应短时段车道宽度、车道功能和车道数;将各进口直行、左转方向在设定时间段内到达的车辆数转换为小时流量和各车道的饱和流量,确定临界最大车道流量;根据获取的信息确定左转车辆是否变道至移位左转车道,并确定车辆的安全变道速度引导;确定车辆最大最小加减速度,判断车辆与灯控状态并引导车辆执行速度引导。
