| 摘 要： | 分、合流区通行能力是影响快速路通行能力的重要因素之一,而分、合流影响区的通行能力是制约分、合流区通行能力的关键原因。文章从分析分、合流影响区内的车辆运行特性入手,根据北京、上海、广州等城市大量的实测数据,分别通过统计车头时距、速度-流量关系和饱和流时高频率出现的流率等方法推荐了快速路分、合流影响区的通行能力,为快速路分、合流区的交通规划和设计,交通组织和管理的改善提供了理论基础。

| Abstract: | Capacities of Diverging and Merging Areas is an important element in factors which influence the capacity of expressway.While capacity of diverging and merging influence areas is a key issue which restrict the capacity of diverging and merging areas.This article began with analysis of traffic flow characteristics of diverging and merging influence areas,based upon a mass of data collected from Beijing,Shanghai and Guangzhou,studied the capacity of diverging and merging influence areas by statistic time headway,relations of speed and volume and frequently appeared saturated volume,consequently,provided a theoretic base for planning,design of diverging and merging areas,for improvement of traffic organization and management. |
