The invention discloses a method and system for judging the low-speed state of a vehicle on the highway. The method comprises the steps of filtering trajectory data of a target vehicle, and judging the state of the vehicle; if the vehicle state is a low-speed state, determining the position, the highway and the state starting time of the target vehicle at the beginning of the low-speed state, andjudging the road section where the vehicle is located; if the target vehicle is not a to-be-excluded vehicle, determining trajectory data of calculated vehicles around the target vehicle according tothe position where the target vehicle is located at the beginning of the state, the highway where the target vehicle is located and the state starting time; determining a comparison condition corresponding to the vehicle state according to the calculated trajectory data of the vehicle; and judging the low-speed state of the target vehicle according to the state of the target vehicle and the corresponding comparison condition, and giving an alarm. According to the embodiment of the invention, the method does not depend on external equipment, is low in cost and high in real-time performance, canmonitor the vehicle in all ranges, helps a driver to correct wrong behaviors, provides help for the vehicle and the driver, and reduces the potential safety hazards on the highway.
本申请公开了一种用于判断高速路上车辆的低速状态的方法和系统,包括:对目标车辆的轨迹数据进行过滤后,判断车辆状态;若车辆状态为低速状态,则确定目标车辆的低速状态开始时所在位置、所在高速路和状态开始时间,并判断车辆所在路段;若目标车辆为非待排除车辆,则根据状态开始时所在位置、所在高速路和状态开始时间,确定目标车辆周边的计算车辆的轨迹数据;根据计算车辆的轨迹数据,确定与车辆状态对应的比较条件;根据目标车辆状态和对应的比较条件,判断目标车辆的低速状态,并报警。本申请的实施方式能够不依赖外接设备,成本低、具有强实时性、可以监控所有范围的车辆,帮助司机纠正错误行为车辆和司机提供帮助,减少高速上的安全隐患。
