The invention discloses a driving style identification method based on traffic conflicts. The method comprises the following steps: collecting driving track data, and extracting vehicle dynamics parameters and lane changing behavior characterization parameters of a single vehicle and traffic conflict parameters generated by vehicle interaction based on the driving track data; constructing a driving style characterization parameter set according to the vehicle kinetic parameters of the single vehicle, the lane changing behavior characterization parameters and traffic conflict parameters generated by vehicle interaction, reducing the data dimension of the driving style characterization parameter set by adopting factor analysis, and extracting main factors of the driving style characterization parameter set; identifying the driving style represented by the main factor by using three clustering algorithms, so that the driving style can be rapidly and accurately identified, and the accuracy of driving style identification can be effectively improved; and the classification result is verified by adopting the traffic conflict severity and the conflict type, so that the influence of the driving style on the road traffic safety can be reflected more directly.

    本发明公开了一种基于交通冲突的驾驶风格识别方法通过采集行车轨迹数据,基于行车轨迹数据,提取单个车辆的车辆动力学参数、换道行为表征参数以及车辆交互产生的交通冲突参数,根据单个车辆的车辆动力学参数、换道行为表征参数以及车辆交互产生的交通冲突参数构建驾驶风格表征参数集合,采用因子分析降低驾驶风格表征参数集合的数据维度,提取驾驶风格表征参数集合的主因子,利用三种聚类算法识别主因子表征的驾驶风格,能够实现对驾驶风格的快速准确识别,可以有效提高驾驶风格识别的精度;采用交通冲突严重性和冲突类型对分类结果进行验证,可以更直接地反映出驾驶风格对道路交通安全的影响。
