【摘要】：为考察不同驾驶风格驾驶员在高速公路上的换道行为,对36名驾驶员进行了驾驶模拟实验研究和问卷调查.采用K-中心聚类方法将驾驶员分为谨慎型、普通型和激进型.基于驾驶模拟实验所得的134次换道过程记录,提取了换道频次、持续时间、平均速度、横向加速度峰值、与前车相对距离以及碰撞时间等数据,并采用单因素方差分析方法对这些数据进行对比分析.结果表明:不同风格驾驶员换道行为存在显著差异;随着谨慎程度的增加,换道频次和换道平均速度降低,车间相对距离和碰撞时间均增大,从而提升了换道过程的安全性.研究结果可提升交通仿真软件中换道行为模型的精细化程度,并为驾驶人层面交通安全政策的制定提供参考.
[Abstract]:In order to investigate the changing behavior of drivers with different driving styles on the freeway, 36 drivers were investigated with a simulated driving experiment and a questionnaire survey. Drivers were classified into cautious type, common type and radical type by using K-center clustering method. Based on 134 track changing process records obtained from driving simulation experiments, data such as frequency, duration, average velocity, peak transverse acceleration, relative distance from the front car and collision time were extracted. A single factor variance analysis method was used to compare these data. The results show that there are significant differences between drivers in different styles, and with the increase of caution, the frequency and average speed of changing lanes decrease, the relative distance of workshop and the time of collision increase, thus enhancing the safety of the course of changing lanes. The results of the study can improve the refinement of the traffic change behavior model in the traffic simulation software, and provide a reference for the formulation of the traffic safety policy at the driver level.
