The invention discloses a confluence area conflict identification and early warning method and system based on a driving risk field, relates to the technical field of intelligent traffic management and control, and aims to solve the problem that traffic accidents are caused by the fact that the influence of the vehicle size, the conflict angle of mainline vehicles and ramp vehicles and the like on confluence risks is not considered in an existing method. According to the method, the conflict condition of the main line vehicles and the ramp vehicles in the confluence area is evaluated by establishing the vehicle driving risk field, real-time early warning of drivers in the confluence area is realized by means of the vehicle-road cooperation technology, traffic accidents are avoided, the driving safety of the vehicles is guaranteed, the energy consumption is reduced, and the passing efficiency of the whole confluence area is improved.

    一种基于行车风险场的合流区冲突识别预警方法及系统,涉及智能交通管理与控制技术领域,针对现有方法未考虑车辆尺寸及主线车辆与匝道车辆冲突角度等对合流风险的影响,进而导致交通事故的问题,本申请通过建立车辆行车风险场来评估合流区主线车辆与匝道车辆的冲突状况,并借助车路协同技术实现对合流区驾驶员的实时预警,避免交通事故的发生,保障车辆的行车安全,降低能耗,提高整个合流区的通行效率。
