The embodiment of the invention discloses a left-turn lane vehicle regulation and control method and device and a medium, belongs to the technical field of intelligent traffic, and solves the problem that the vehicle passing efficiency of a left-turn lane is low. Comprising the following steps: acquiring road traffic data, and determining a U-turn vehicle queue corresponding to a left-turn road according to the road traffic data; based on the speed and the position of the pilot vehicle in the U-turn vehicle queue, constructing a central guardrail opening regulation and control function model, and determining a reference U-turn position corresponding to the U-turn vehicle queue and an opening size required by U-turn through the function model; controlling the central guardrail to move according to the reference U-turn position and the size of the opening required by U-turn, so that the central guardrail has a vehicle U-turn opening at the corresponding position; determining a left-turn vehicle queue according to the left-turn road remaining vehicles; and by taking the queuing length corresponding to the left-turn vehicle queue and the average consumed time of the left-turn vehicles passing through the intersection as optimization indexes, constructing a left-turn vehicle passing optimization function so as to regulate and control the left-turn vehicle queue.
本申请实施例公开了一种左转车道车辆调控方法、设备及介质,属于智能交通技术领域,解决左转车道车辆通行效率较低的问题。包括,获取道路交通数据,根据道路交通数据确定出左转道路对应的掉头车辆队列;基于掉头车辆队列中领航车的速度与位置,构建中央护栏开口调控函数模型,通过函数模型确定出掉头车辆队列对应的参考掉头位置与掉头所需开口尺寸;根据参考掉头位置与掉头所需开口尺寸,控制中央护栏进行移动,以使中央护栏在相应位置出现车辆掉头开口;根据左转道路剩余车辆确定出左转车辆队列;以左转车辆队列对应的排队长度与左转车辆通过交叉路口的平均消耗时间为优化指标,构建左转车辆通行优化函数,以对左转车辆队列进行调控。
