The invention discloses a road driving risk early warning method for a dynamic traffic bottleneck in an intelligent network connection environment. The method comprises the following steps: 1, establishing a road plane rectangular coordinate system; 2, acquiring a dynamic traffic bottleneck and vehicle related information at the current moment; 3, predicting a dynamic traffic bottleneck and target vehicle related information at the next moment; 4, predicting a road boundary risk field value, a superposed dynamic traffic bottleneck risk field value and a superposed vehicle risk field value of the target vehicle at the next moment; 6, predicting the total risk field value of the target vehicle at the next moment; and 7, judging whether a risk early warning signal is sent to the target vehicle or not. According to the method, the road, the dynamic traffic bottleneck and the vehicle related information at the current moment can be obtained in the intelligent network connection environment, the dynamic risk value of the target vehicle in the advancing process at the next moment is predicted, and whether the risk early warning signal is sent to the target vehicle or not is judged, so that traffic accidents are prevented, and the road traffic safety level is improved.
本发明公开了一种智能网联环境下面向动态交通瓶颈的道路行车风险预警方法,其步骤包括:1、建立道路平面直角坐标系;2、获取当前时刻动态交通瓶颈及车辆相关信息;3、预测下一时刻动态交通瓶颈及目标车辆相关信息;4、预测下一时刻目标车辆的道路边界风险场值、叠加动态交通瓶颈风险场值和叠加车辆风险场值;6、预测下一时刻目标车辆的总风险场值;7、判断是否对目标车辆发出风险预警信号。本发明能通过在智能网联环境下获取当前时刻的道路、动态交通瓶颈及车辆相关信息,预测下一时刻目标车辆在行进过程中的动态风险值,判断是否对目标车辆发出风险预警信号,从而预防交通事故的发生,提高道路交通安全水平。
