The invention relates to an analysis method for early turning around of vehicles at an intersection, and belongs to the technical field of traffic. According to the method, key geometric parameter models such as a model for judging the distance between the position of a vehicle turning-around opening in advance and the upstream and downstream intersection, a turning-around traffic flow queuing length model, a turning-around opening size model are constructed, and a road section turning-around vehicle average delay calculation method is provided and is compared with an intersection turning scheme to obtain threshold conditions of left turn and turn-around traffic flow of the turn-around lane when the road section turns around in advance. The method has the advantages that the operation is simple, the calculation is convenient, the intersection vehicle turning-around setting can be analyzed by applying a more scientific and quantitative method according to the actual condition of road traffic, the key geometric setting parameter calculation method and the threshold flow condition of the vehicle turning-around in advance are obtained, and the intersection turning-around organization design is optimized.

    本发明涉及一种交叉口车辆提前掉头的分析方法,属于交通技术领域。本发明通过构建了车辆提前掉头开口位置与上下游交叉口距离的判别模型、掉头车流排队长度模型以及掉头开口大小等关键几何参数模型,提出了路段提前掉头车均延误计算方法,并和交叉口掉头方案相比较,得出设置路段提前掉头时掉头车道左转及掉头车流量的阈值条件。该方法的优点在于操作简单、便于计算,可以根据道路交通的实际状况,应用更加科学定量的方法对交叉口车辆掉头设置进行分析,得出车辆提前掉头关键几何设置参数计算方法及阈值流量条件,优化交叉口掉头组织设计。
