研究应用视频摄像设备对山东省青岛市周围3条高速公路进行交通流运行数据采集,得出我国东部典型地区车流运行特性。并通过与1998年广佛高速公路车流运行特性对比分析,发现我国现状高速公路交通流运行特性与过去相比车流运行速度选择空间趋于集中,变化范围在75～115km/h,较1998年有所提升。研究成果可为开展新一轮公路工程设计规范编制提供决策支持。
Research and application of video camera equipment on the three freeways around Qingdao City, Shandong Province traffic flow data acquisition, draw a typical area of eastern China traffic flow characteristics. And through the comparison with the traffic characteristics of Guangfo Expressway in 1998, it is found that the traffic flow characteristics of current expressways in our country tend to be more concentrated than those in the past in the range of 75 ~ 115km / h, Promoted. The research results can provide decision support for the development of a new round of highway engineering design code.
