The invention provides an expressway visibility real-time monitoring method and system. The method comprises the following steps: acquiring visibility data of an expressway target section corresponding to the expressway in real time to generate a current visibility recognition result of the expressway target section; judging whether the visibility recognition result meets a preset visibility condition or not, and if not, marking each vehicle currently driving in the target section of the expressway as a secondary recognition vehicle; and carrying out license plate recognition on the secondary recognition vehicle to obtain a corresponding license plate recognition result, and judging whether to send a visibility risk prompt message to the vehicle-mounted equipment of the secondary recognition vehicle based on a preset cloud service based on the license plate recognition result. According to the invention, all-weather visibility real-time monitoring and visibility risk early warning can be realized for the expressway, so that the safety of vehicles running on the expressway can be improved, and the operation and safety management level of the expressway under severe weather conditions can be greatly improved.
本申请提供一种高速公路能见度实时监测方法及系统,方法包括:实时采集自身对应的高速公路目标段的能见度数据以生成高速公路目标段当前的能见度识别结果;判断能见度识别结果是否满足预设的能见度条件,若否,则将当前行驶在高速公路目标段内的各个车辆标识为二次识别车辆;对二次识别车辆进行车牌识别,以得到对应的车牌识别结果,以基于车牌识别结果判断是否基于预设的云服务向二次识别车辆的车载设备发送能见度风险提示消息。本申请能够针对高速公路实现全天候的能见度实时监测和能见度风险预警,进而能够提高行驶在高速公路中车辆的安全性,并能够大幅度提升高速公路在恶劣气象条件下的运营与安全管理水平。
