The invention relates to the technical field of road traffic control, in particular to an intelligent early warning method for tunnel driving traffic accident risks. The method comprises the following steps: acquiring monitoring video data of a vehicle in a process of passing through a tunnel, determining a driving speed and a course angle of the vehicle according to the position of the vehicle in an adjacent frame image of the monitoring video data, and determining an offset index of the vehicle at adjacent moments according to the driving speed and the course angle; according to the deviation index, determining a first instability degree before the vehicle passes through the tunnel and a second instability degree when the vehicle passes through the tunnel, and determining a driving state index when the vehicle passes through the tunnel; based on the distance between the two vehicles at the same moment and the driving state indexes of the two vehicles, the accident occurrence probability of the two vehicles is determined, and high-risk traffic accident early warning is carried out on the two vehicles according to the accident occurrence probability. According to the invention, the reliability and safety of danger early warning in the driving process of the vehicle on the tunnel road section can be improved.

    本发明涉及道路交通控制技术领域,具体涉及一种隧道行车交通事故风险智能预警方法。方法包括:获取车辆在穿行隧道过程中的监控视频数据,根据监控视频数据的相邻帧图像中车辆的位置确定车辆的行驶速度和航向角度,根据行驶速度和航向角度确定车辆在相邻时刻的偏移指标;根据偏移指标,确定车辆在穿行隧道前的第一不稳定程度和车辆在穿行隧道中的第二不稳定程度,确定车辆在穿行隧道过程中的行驶状态指标;基于同一时刻两辆车辆间的距离和两辆车辆的行驶状态指标,确定两辆车辆的事故发生概率,根据事故发生概率对两辆车辆进行高危交通事故预警。本发明能够提升车辆在隧道路段行驶过程中危险预警的可靠性与安全性。
