The invention discloses a crossroad control method based on combination of a variable turning lane and lane changing, and the method specifically comprises the following steps: S1, starting a crossroad variable turning lane and lane changing control algorithm, and enabling a road test unit to receive vehicle information and transmit the vehicle information to a central server; s2, controlling a vehicle needing to change a lane in the lane change control area to change to a target lane; s3, calculating the passing priorities of vehicles which are not distributed with the passing right in the speed regulation control area; and S4, adjusting the speed of the vehicle in the speed regulation control area to ensure that the vehicle can safely and efficiently pass through the crossroad. According to the invention, when the traffic flow at the crossroad is unbalanced, especially the traffic flow at the same road section is unbalanced, the vehicle is changed from a traffic-crowded lane to a stable-traffic lane through a method of combining a flexibly-changed turning lane with lane changing and speed regulation, so that the purpose of sharing the traffic flow is achieved; steering vehicles with large traffic flow can pass through the intersection from multiple lanes at the same time, the average waiting time of the vehicles is shortened, and the passing efficiency of the intersection is improved.
本发明公开了一种基于可变转向道与换道结合的十字路口控制方法,具体包括以下步骤:S1、启动十字路口可变转向道与换道控制算法,路测单元接收车辆信息并传输给中央服务器;S2、控制换道控制区内需要换道的车辆换向目标车道;S3、计算调速控制区内尚未分配通行权的车辆的通行优先级;S4、调整调速控制区内车辆的速度,保证其能安全高效地通过十字路口。本发明在十字路口交通流不平衡,特别是同一路段的交通流不平衡时,通过可以灵活变化的转向道与换道、调速结合的方法,让车辆从交通拥挤的车道换到交通平稳的车道,从而达到分摊交通流的目的,让交通流较大的转向车辆可以从多个车道同时通过路口,减少车辆的平均等待时间,提高十字路口的通行效率。
