摘　　要：在大量实际观测交通流数据的基础上 ,在研究跟驰车辆表现出的运行特性基础上 ,本文提出一种基于跟驰特性的车型分类新方法。数据分析表明 ,将自然交通流中的车辆划分为大型车和小型车就可以刻画出自然交通流中不同车型所产生的影响。在此基础上 ,深入分析了小型车和大型车的分别作为前导车与后随车的跟驰特性 ,探讨了车型对驾驶员选择跟驰间隔所产生的物理与心理影响因素 ,并对车速的影响进行了分析。Based on a large number of field data, a new classification, categorized by car and large vehicle, is provided for car-following theory study on the basis of kinematical characteristics. The classification, verified by field data, is simple and effective for combined traffic flow study.The kinematical characteristics of car and large vehicle as leader or follower in car-following behaviors are analyzed in detail. The physical and psychic factors stimulated by different type of vehicle on driver′s choice of headway are discussed in this article.The travel speed has different effects on headway choice in different car-following type.
