| 摘 要： | 对22条双车道公路直线路段进行调查,获得了路侧净空与车辆运行速度的关系;以基准道路条件建立了路侧净空对运行速度的影响模型;采用R语言统计分析软件分析了街道化路段运行速度、建筑物距离和正常路段运行速度三者之间的相关关系,并采用统计回归的方法建立了街道化对运行速度的影响关系模型。结果表明:运行速度与路侧净空之间存在对数关系;街道化路段运行速度与建筑物距离相关性很强,而与正常路段运行速度相关性很低。

| Abstract: | Based on the speed survey of 22 tangent segments of two-lane highway,the relation of roadside clear zone and operating speed was obtained.Then,the model of influence of clear zone on the fiducial operating speed was built.The relations of operating speed,fiducial speed and the interval between the edge of the road and the street buildings were studied using R language program.The model of the influence of roadside development on operating speed was built based on the results using statistical regression ana... |
