为研究不同驾驶人在追尾事故中的驾驶行为特征,用Near-crash事件代替真实碰撞事件,选取一段城市快速道路开展实车试验。首先测试21名驾驶人实驾时的最大减速度、制动至最大减速度时间、平均减速度、碰撞时间倒数(TTCi)4个指标;然后用Mobileye等设备提取数据,得到不同性别、驾驶经验、驾驶风格的驾驶人指标因素;最后对数据进行方差分析。结果表明:Near-crash事件中,女性驾驶人平均减速度、最大减速度大于男性驾驶人,女性驾驶人更倾向于急刹车;经验影响驾驶人的平均减速度、最大减速度;熟练驾驶人制动到最大减速度时间长,制动过程更加平稳;激进型驾驶风格的驾驶人车头时距(THW)小于保守型驾驶人。
In order to study the driving behavior characteristics of different drivers in rear-end accidents, Near-crash events are used to replace the actual collision events, and a section of urban expressways is selected to carry out real-vehicle tests. First of all, we test the maximum deceleration of 21 drivers, the maximum braking time from braking, the average deceleration and the reciprocal of the crash time (TTCi). Then use Mobileye and other devices to extract the data to get the information of different genders and driving experience , Driving style indicators of the driver; the final analysis of variance data. The results show that in the Near-crash event, the average deceleration and the maximum deceleration of female drivers are greater than those of male drivers, and the female drivers are more likely to be braked hard; the experience affects the average driver deceleration and maximum deceleration; Move to the maximum deceleration for a long time, the braking process is more stable; radical driving style driver’s head time (THW) is less than the conservative driver.
