| 摘 要： | 采用VTR摄像机记录车辆通过观测断面处的侧向位置,应用Virtualdub视频分析软件判读车辆外侧前轮至道路中心线的距离.选取典型双车道公路上8处曲线为试验段,根据试验数据的统计分析结果,得到以下主要研究结论:车辆在进入曲线段时,行驶轨迹存在着朝曲线内侧偏移的运动趋势;在出曲线段时,车辆行驶轨迹趋向朝曲线外侧偏移;平曲...

| Abstract: | The lateral positions while vehicles passing experimental observation sections were recorded by using video tape recorder(VTR)cameras,the distance from outside front wheel of vehicles to centerline of highway was identified by applying video process software VirtualDub.According to statistical analsis results of experimental data collected in eight curves on typical two-lane highway,it is concluded that(1) the path has a tendency to shift inward the curves as vehicles entering the curves and tend to shift o... |
