The embodiment of the invention provides an expressway driving safety early warning method and system, and relates to the technical field of road safety, and the method comprises the steps: comparing the driving state of each vehicle with a first early warning condition, and determining the vehicle with the driving state meeting the first early warning condition as a first vehicle; under the condition that the first vehicle exists, a second early warning condition corresponding to the environment state is determined according to the environment state of the current environment; the driving state of the first vehicle is compared with a second early warning condition, and the first vehicle with the driving state meeting the second early warning condition is determined as a second vehicle; determining whether to determine the second vehicle as a target vehicle or not according to the driving state of the second vehicle within the preset duration; and returning the vehicle information of the target vehicle to the cloud to perform safety early warning on the target vehicle. The invention aims to more accurately determine a low-speed driving vehicle which needs to be subjected to safety early warning.
本申请实施例提供了一种高速道路行车安全预警方法及系统,涉及道路安全技术领域,方法包括:将各个车辆的行驶状态分别与第一预警条件进行对比,并将行驶状态满足第一预警条件的车辆确定为第一车辆;在存在第一车辆的情况下,根据当前所处环境的环境状态,确定与环境状态对应的第二预警条件;将第一车辆的行驶状态与第二预警条件进行对比,并将行驶状态满足第二预警条件的第一车辆确定为第二车辆;根据第二车辆在预设时长内的行驶状态,确定是否将第二车辆确定为目标车辆;返回目标车辆的车辆信息至云端,以对目标车辆进行安全预警。旨在更准确地确定到需要进行安全预警的低速行驶的车辆。
