The invention belongs to the technical field of expressway collision accident prevention, and particularly relates to an expressway operation site vehicle mistaken intrusion early warning method and early warning system fused with a driving intention. According to the highway operation site vehicle intruding early warning method fusing the changing driving intention, the vehicle intruding risk is predicted by integrating the video equipment, the intruding risk of the vehicle with the intruding risk is determined based on the millimeter wave radar, and the changing intruding intention is applied to the track prediction model, so that the vehicle intruding risk is determined. The accuracy of mistaken intrusion early warning can be further improved, and the operators are warned in time through the early warning slave machine, so that the operators are evacuated as soon as possible, and the accident rate is reduced; in addition, through cooperative complementation of the video equipment and the millimeter wave radar, the false alarm rate is remarkably reduced, and the credibility of operators on the mistaken intrusion early warning system is improved.
本发明属于高速公路碰撞事故防范技术领域,具体涉及一种融合驾驶意图的高速公路作业现场车辆误闯入预警方法及预警系统。本发明提供的融合变化驾驶意图的高速公路作业现场车辆误闯入预警方法,综合视频设备预测车辆误闯入风险,并基于毫米波雷达对存在误闯入风险车辆进行误闯入风险确定,其中将变化的误闯入意图应用于轨迹预测模型中,有助于进一步提高误闯入预警的准确率,通过预警从机对作业人员进行及时警告,使其尽快疏散,降低事故率;而且本发明通过视频设备和毫米波雷达的协同互补,显著降低了虚警率,提高作业人员对误闯入预警系统的信任度。
