The invention relates to a tunnel safe passing speed prediction system and method, and the system comprises a vehicle detection module which detects whether a vehicle is about to drive into or out of a tunnel, and transmits the detection information to a control unit after the vehicle information is detected; a control unit, used for sending control information to the road information detection module after receiving the detection information; a road information detection module, used for detecting road information of lanes in a tunnel entrance safety area, a tunnel entrance monitoring section, a tunnel exit safety area and a tunnel exit monitoring section after receiving the control information; the road information comprising the driving speed of two adjacent vehicles inside and outside the tunnel entrance/exit and the distance between the two vehicles; a data analysis module, used for calculating the current maximum predicted safety speed of each lane at the entrance of the tunnel and each lane at the exit of the tunnel according to the road information; and a display screen, used for displaying the current maximum safety speed and road condition information of each lane. The problem that the traffic condition of the front tunnel cannot be known in the prior art is solved.

    本发明涉及一种隧道安全通行速度预测系统及方法,该系统包括:车辆检测模块,检测是否有车辆即将驶入或驶出隧道,当检测到车辆信息后,发送检测信息至控制单元;控制单元,用于接收到检测信息后,发送控制信息至道路信息检测模块;道路信息检测模块,用于接收到控制信息后,检测隧道入口安全区域、隧道入口监测段、隧道出口安全区域和隧道出口监测段内各车道的道路信息;道路信息包括:隧道入/出口内外相邻两车的行驶速度和两车的距离;数据分析模块,用于根据道路信息,计算隧道入口各车道和隧道出口各车道当前最大的预测安全速度;显示屏,用于显示各车道当前最大的安全速度及路况信息。解决了现有技术中不能知晓前方隧道通行状况的问题。
