The invention provides an intersection turning overspeed judgment method and device based on trajectory data and a storage medium, and belongs to the technical field of traffic safety. The intersection turning overspeed judgment method based on the trajectory data comprises the following steps: acquiring continuous target number of trajectory point data from trajectory data reported by a vehicle; wherein the continuous target number of trajectory point data comprises latest trajectory point data, and the trajectory point data comprises position information of trajectory points and vehicle speeds of the trajectory points; obtaining target intersection position information from a preset intersection information database based on the position information of the latest track point under the condition of determining that the vehicle is in a turning state; wherein the target intersection is the intersection closest to the newest track point; acquiring the vehicle speed of a target trajectory point closest to the target intersection from the continuous trajectory point data of the target number based on the target intersection position information; and if the vehicle speed of the target track point exceeds a preset speed threshold value, determining that the intersection turning of the vehicle is overspeed.
本发明提供一种基于轨迹数据的路口转弯超速判断方法、装置及存储介质,属于交通安全技术领域。所述基于轨迹数据的路口转弯超速判断方法,包括:从车辆上报的轨迹数据中获取连续的目标数量的轨迹点数据;其中,连续的目标数量的轨迹点数据包括最新轨迹点数据,轨迹点数据包括轨迹点的位置信息和轨迹点的车辆速度;确定车辆处于转弯状态的情况下,基于最新轨迹点的位置信息从预设路口信息数据库中获取目标路口位置信息;其中,目标路口为距离最新轨迹点最近的路口;基于目标路口位置信息从连续的目标数量的轨迹点数据中,获取距离目标路口最近的目标轨迹点的车辆速度;若目标轨迹点的车辆速度超过预设速度阈值,则确定车辆的路口转弯超速。
