The invention discloses a radar-based parking queuing length determination method and system, and relates to the field of intelligent traffic management, and the method comprises the following steps: obtaining a vehicle with a parking intention and a parking time point according to a preset amplification buffer link and a triple standard deviation criterion; and whether a started vehicle exists in the vehicles in the stop state or not is judged according to the triple standard deviation criterion, so that a double-buffer structure is fully utilized, the time information of the vehicles from advancing to parking to advancing is utilized, the driving habit of the vehicles from advancing to parking and the driving habit of the vehicles from parking to advancing are integrated, and the driving efficiency is improved. And finally, the calculation of the vehicle parking intention is completed, so that the stability of parking queuing length determination can be improved. And queuing planning is carried out on each parking target by using a high-precision map, so that more accurate calculation of the queuing length is realized, and the problem of inaccurate calculation of the queuing length caused by different detection positions of the detected target by a radar is avoided.

    本发明公开一种基于雷达的停车排队长度确定方法及系统,涉及智能交通管理领域,包括如下步骤:根据预设放大缓冲环节和三倍标准差准则获取具有停车意图的车辆和停车时间点,并且通过三倍标准差准则判断所述处于停止状态的车辆中是否存在启动的车辆,从而充分利用了双缓冲结构,对车辆在行进到停车再到行进的时间信息的利用,整合了车辆由行进到停车的驾驶习惯和由停车到行进的驾驶习惯,最终完成车辆停车意图的计算,从而可以提升停车排队长度确定的稳定性;并且利用高精度地图对每个停车目标进行排队规划,实现更精准的排队长度的计算,避免了雷达由于被测目标检测位置的不同造成的排队长度计算不准的问题。
