The invention discloses a highway traffic jam judgment method and system. The method comprises the following steps: judging the vehicle state according to track data of a target vehicle; according tothe parking state or the low-speed state of the target vehicle, determining the 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; according to the 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 trajectory data of calculated vehicles around the target vehicle; determining a comparison condition corresponding to the vehicle state according to the trajectory data of the calculated vehicles; and judging whether the highway is blocked or not according to the target vehicle state and the corresponding comparison condition. Trajectory data of calculated vehicles around the targetvehicle is determined by monitoring the trajectory number of the target vehicle in real time and judging the vehicle state, the comparison condition corresponding to the vehicle state is determined according to the trajectory data of the calculated vehicles, whether traffic jam occurs on the highway or not is judged, and traffic jam on the highway can be judged without depending on external equipment.
本申请公开了一种高速路堵车的判断方法和系统,包括:根据目标车辆的轨迹数据判断车辆状态;根据目标车辆的停靠状态或低速状态,确定目标车辆的停靠状态或低速状态开始时所在位置、所在高速路和状态开始时间;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,判断高速路是否堵车。通过实时监控目标车辆的轨迹数,据判断车辆状态,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,判断高速路是否堵车,不依赖外部设备即可以对高速路堵车进行判断。
