The invention discloses a driving behavior evaluation method and device, equipment and a medium, and relates to the technical field of intelligent traffic, and the method comprises the steps: determining auxiliary track points from candidate track points according to candidate direction angles corresponding to the adjacent candidate track points of a target vehicle; taking a preset time period before the acquisition time of each auxiliary track point as a candidate detection time period corresponding to each auxiliary track point, and determining a target track point from each auxiliary track point according to the average driving speed of the target vehicle in each candidate detection time period; and according to the target trajectory point number of the target trajectory points, evaluating the driving behavior generated by the driver of the target vehicle in the target time period. According to the invention, the supervision for ensuring the safe driving behavior of the driver in the turning scene can be enhanced, so that the bad driving behavior of the driver can be corrected in time, and the probability of accidents caused by improper observation of the driver in the turning scene can be reduced.

    本发明公开了一种驾驶行为的评估方法、装置、设备和介质,涉及智能交通技术领域,包括:根据目标车辆在相邻的候选轨迹点分别对应的候选方向角,从各候选轨迹点中确定辅助轨迹点;将各辅助轨迹点的采集时刻之前的预设时间段,作为各辅助轨迹点对应的候选检测时间段,并根据目标车辆在各候选检测时间段内的平均行驶速度,从各辅助轨迹点中确定目标轨迹点;根据目标轨迹点的目标轨迹点数量,对目标车辆的驾驶员在目标时间段内产生的驾驶行为进行评估。本发明有利于加强对驾驶员在转弯场景下保证安全驾驶行为的监管力度,以便及时更正驾驶员存在的不良驾驶行为,降低在转弯场景下由于驾驶员观察不到位导致事故发生的概率。
