The invention relates to a vehicle collaborative lane changing guiding method based on highway traffic accidents, which comprises the following steps: determining a traffic accident occurrence road section, detecting the traffic flow condition of the traffic accident occurrence road section, and obtaining accident information; based on the accident information, an accident influence degree function is constructed, and whether lane changing guidance needs to be carried out on a rear vehicle or not is judged through the accident influence degree function; if lane changing guidance needs to be carried out on the rear vehicle, a traffic accident safety potential field model is constructed, corresponding vehicle collaborative lane changing guidance strategies are provided according to different road conditions, meanwhile, the safe critical distance of vehicle lane changing and the optimal lane changing position of the vehicle are calculated based on the safety potential field theory, and the lane changing strategies are executed. The invention provides a vehicle and motorcade guiding strategy for various scenes of highway traffic accidents, and guides vehicles and motorcades behind an accident point to safely and quickly pass through an accident road section.
本发明涉及一种基于高速公路交通事故下的车辆协同换道引导方法,包括:确定交通事故发生路段,检测交通事故发生路段的交通流状况,获取事故信息;基于事故信息,构建事故影响度函数,通过事故影响度函数判断是否需要对后方车辆进行换道引导;若需要对所述后方车辆进行换道引导,则构建交通事故安全势场模型,根据不同的道路条件提出相应的车辆协同换道引导策略,同时基于安全势场理论计算车辆换道的安全临界距离以及车辆的最佳换道位置,执行换道策略。本发明针对高速公路交通事故发生的多种场景,提出车辆及车队的引导策略,引导事故点后方车辆和车队安全快速通过事故路段。
