摘要 跟驰行为谱可有效反映不同驾驶场景下及不同驾驶人类型的跟驰行为特征.基于高逼真度驾驶模拟器搭建15种典型跟驰驾驶场景,获取相应的驾驶行为数据;根据驾驶风格和驾驶经验将驾驶人分为熟练-中立型、熟练-激进型、熟练-保守型、非熟练-中立型、非熟练-激进型、非熟练-保守型等6种类型,以速度、加/减速度、油门/刹车踏板受力、车头时/间距、相对速度、TTC,以及TIT等指标作为跟驰行为谱构成要素,构建了6类驾驶人在15种跟驰驾驶场景下的跟驰行为谱;并以近距离跟驰过程中的风险评估为案例探讨了跟驰行为谱的应用. Car-following ethogram can effectively reflect the characteristics of car-following behaviors in different driving scenarios and different types of drivers.Based on the high fidelity driving simulator,15 typical car-following driving scenes were built and the corresponding driving behavior data were obtained.According to driving style and driving experience,drivers were divided into six types:skilled-neutral,skilled-aggressive,skilled-conservative,unskilled-neutral,unskilled-aggressive and unskilled-conservative.With speed,acceleration/deceleration,throttle/brake pedal force,headway/spacing,relative speed,TTC and TIT as the constituent elements of the following ethogram,the following ethogram of six types of drivers in 15 following driving scenarios was constructed.Taking the risk assessment in the process of close follow-up as an example,the application of follow-up ethogram was discussed.
