The invention discloses an intersection right-turn vehicle conflict analysis method and device, a storage medium and a terminal. The method comprises the following steps: calculating passing parameters of each right-turn motor vehicle passing through a to-be-analyzed right-turn intersection according to driving track data passing through the to-be-analyzed right-turn intersection within a preset time period; analyzing signal phases having right-turn conflicts with the right-turn intersection to be analyzed and signal phases having no right-turn conflicts with the right-turn intersection to be analyzed according to the actual operation parameters of the signal lamps at the current intersection; according to the passing parameters of each right-turn motor vehicle, calculating first average turning time under the signal phase of the right-turn conflict and second average turning time under the signal phase without the right-turn conflict; and determining the conflict severity of the right-turn intersection to be analyzed according to the first average turning time and the second average turning time. According to the method and the device, the conflict severity of the right-turn vehicles, the pedestrians and the non-motor vehicles at the intersection is quantitatively analyzed, so that refined intersection order management is realized, and the right-turn passing efficiency and safety are improved.

    本发明公开了一种路口右转车辆冲突分析方法、装置、存储介质及终端,方法包括:根据预设时间段内经过待分析右转路口的行车轨迹数据计算每辆右转机动车通过待分析右转路口的通行参数;根据当前十字路口上信号灯的实际运行参数分析与所述待分析右转路口存在右转冲突的信号相位以及无右转冲突的信号相位;根据每辆右转机动车的通行参数,计算右转冲突的信号相位下的第一平均转弯时间以及无右转冲突的信号相位下的第二平均转弯时间;根据第一平均转弯时间和第二平均转弯时间确定待分析右转路口的冲突严重程度。本申请通过对路口右转的车辆与行人、非机动车进行冲突严重程度的定量分析,实现了精细化路口秩序治理,进而提高了右转通行效率和安全性。
