| 摘 要： | 为了研究稳定跟车状态下车头间距变化的规律,利用跟车行为的时间序列数据,证明了在稳定跟车状态后车速度的变化趋势基本上沿袭前车速度的变化轨迹.当后车速度增加时,车头间距也相应变大;当后车速度下降时,车头间距也相应减小;当后车速度基本保持不变时,车头间距也在一定幅度内保持稳定.后车司机在改变跟车速度时,把车头间距调整到合适的水平,以适应跟车速度的变化.当跟车速度维持在某一个速度水平时,车头间距在一定范围内进行小幅度调整,试图接近期望车头间距.期望车头间距、期望车头时距与后车速度之间是抛物线型的统计回归关系.

| Abstract: | The model that describe movement disciplinarian of distance headway in car following is an important content of car following theory.In this paper,time serial car following data proves that speed movement of a following car keeps pace with a leading car,while speed of following car increases,distance headway increases too,and while speed movement of a following car descends,distance headway decreases.There are expectation distance headway at various speed of following cars.The Stat.Regression Models of expe... |
