本发明涉及高速公路交通安全技术领域,具体公开了高速公路隧道入口段事故智慧防控与预警系统,包括数据采集单元、处理系统和预警显示单元,采集单元用于采集隧道外车辆的车速、车距和车辆的实时视频信息;处理系统根据车辆的实时视频信息识别出车辆的车牌序列,处理系统根据采集单元采集到的车速、车距并基于安全车距模型计算得到的临界安全行车间距;当车辆超速时,处理系统控制预警显示单元显示该车辆的超速预警信息;当车辆车距小于等于临界安全行车间距时,处理系统控制预警显示单元显示该车辆的追尾预警信息。本方案用以解决现有技术中无差别地针对所有驾驶员所做的安全防控手段对隧道入口交通事故的降低效果并不明显的问题。

    The invention relates to the technical field of highway traffic safety, and particularly discloses a highway tunnel entrance section accident intelligent prevention and control and early warning system, which comprises a data acquisition unit, a processing system and an early warning display unit, and is characterized in that the acquisition unit is used for acquiring vehicle speeds, vehicle distances and real-time video information of vehicles outside a tunnel; the processing system identifies a license plate sequence of the vehicle according to the real-time video information of the vehicle, and the processing system calculates a critical safe driving distance based on a safe vehicle distance model according to the vehicle speed and the vehicle distance acquired by the acquisition unit; when the vehicle is overspeed, the processing system controls the early warning display unit to display the overspeed early warning information of the vehicle; and when the vehicle distance is smaller than or equal to the critical safe driving distance, the processing system controls the early warning display unit to display rear-end collision early warning information of the vehicle. The system is used for solving the problem that in the prior art, the effect of reducing traffic accidents at a tunnel entrance by safety prevention and control means made for all drivers without difference is not obvious.
