The invention discloses a multi-vehicle cooperation type vehicle afflux method based on vehicle-road cooperation, and relates to the technical field of intelligent transportation, and the method comprises the steps: enabling vehicles to match map information according to real-time positioning data, obtaining afflux point information, judging whether there is a vehicle afflux point or not, entering the next step if there is the vehicle afflux point, and ending if there is no vehicle afflux point; the distance dleft between the current position of the vehicle and the confluence point is calculated, the distance dleft is compared with the confluence scene triggering distance Dtrigger, and when dleft is smaller than Dtrigger, a vehicle confluence request is sent to a roadside scheduling module; the roadside scheduling module obtains the state information of all vehicles in the scene, calculates the scene passing time of each vehicle and then sorts the scene passing time; and the roadside scheduling module establishes a cost function containing a plurality of evaluation targets, calculates to obtain a vehicle afflux mode with the lowest decision cost, obtains a scheduling decision, and then schedules all vehicles according to the scheduling decision. According to the invention, the traffic jam caused by long-time waiting of multi-vehicle convergence is solved, and the traffic efficiency under the inherent traffic capacity is improved.
本发明公开了一种基于车路协同的多车协作式车辆汇入方法,涉及智能交通技术领域,包括车辆根据实时定位数据匹配地图信息,获取汇入点信息,判断是否存在车辆汇入点,若存在则进入下一步骤,若不存在则结束;计算车辆当前位置距汇入点的距离dleft,并将其与汇入场景触发距离Dtrigger进行对比,当dleft<Dtrigger时,向路侧调度模块发送车辆汇入请求;路侧调度模块获取场景中所有车辆的状态信息,并计算各个车辆的场景通过时间然后进行排序;路侧调度模块建立包含多个评价目标的代价函数,并计算得到决策代价最低的车辆汇入方式,得到调度决策,之后根据调度决策对所有车辆进行调度。本发明解决了多车汇入长时间等待导致的交通拥堵,提高了固有交通容量下的通行效率。
