| 摘 要： | 为了研究加/减速跟车状态下两辆车车头间距离的变化规律,本文依据在特定的司机驾驶行为、交通条件和道路条件的基础上获得的实际交通流中的跟车数据,构建了解析加/减速跟车状态下车头间距与跟车速度之间关系模型的方法.当车头间距持续增加,后车司机加速追赶前车期间,车头间距与后车速度之间的关系是线性变化的,车头时距与后车速度之间的关系是指数变化的.当车头间距持续减少,后车司机减速刹车期间,车头间距与后车速度之间的关系是线性变化的,车头时距与后车速度之间的关系是指数变化的.

| Abstract: | The model that describe movement disciplinarian of distance headway in car following is one of the important content of car following theory.Because the factors of infecting distance headway are too mang, and there are not time serial distance headway data,there are not distance headway theory models accepted normally.In this paper,based on the dynamic car-following behavioral data collected by the instrumented GPS vehicle in real traffic flow of given drivers behavioral,traffic and road conditions,the dist... |
