The invention relates to the technical field of tunnel regulation and control, in particular to a tunnel driving speed recommendation method and system, a terminal and a storage medium, and the method comprises the following steps: S1, obtaining tunnel information including tunnel length, tunnel pavement friction and tunnel speed limit, and vehicle information in a tunnel; the information of the vehicles in the tunnel comprises the number of the vehicles in the tunnel, the current distance between the vehicle and a front vehicle, and the current speed and acceleration of the vehicle; s2, calculating the traffic flow density in the tunnel and the safety distance between adjacent vehicles according to the tunnel information and the vehicle information in the tunnel; and S3, calculating a recommended speed based on the tunnel information, the traffic flow density and the safe distance, and pushing the recommended speed to the vehicles in the tunnel. The vehicles run according to respective recommended speeds, so that the interference to traffic flow caused by too fast or too slow speed of individual vehicles can be avoided, and the overall passing efficiency is improved. And energy waste and time delay caused by traffic jam are reduced.
本发明涉及隧道调控技术领域,尤其涉及一种隧道行驶速度推荐方法、系统、终端及存储介质,包括以下步骤:S1,获取隧道信息和隧道内车辆信息,所述隧道信息包括隧道长度、隧道路面摩擦和隧道限速,所述隧道内车辆信息包括隧道内车辆数量、车辆与前车的当前距离、车辆当前速度和加速度;S2,根据隧道信息和隧道内车辆信息计算隧道内的车流密度和相邻车辆之间的安全距离;S3,基于隧道信息、车流密度和安全距离计算推荐速度,并向隧道内的车辆推送推荐速度。车辆都按照各自的推荐速度行驶,能够避免个别车辆速度过快或过慢而对车流造成干扰,提高整体的通行效率。减少了因交通拥堵造成的能源浪费和时间延误。
