摘要
设置集散车道能有效地提高存在交织运行的互通式立交的通行能力.我国现行交通规范中有关集散车道设置方面的规定缺乏统一的技术标准,集散车道的设计具有一定的随意性.参照国内外有关车辆交织运行的相关研究成果,从交织区间长度、主线直行交通量和交通标志的布置等三个方面论述了互通式立交中集散车道的设置原则;结合我国互通式立交的设计要求和工程实例,提出了集散车道的长度、横断面布置和分隔带设计的方法,为集散车道的详细设计提供相应了的理论依据.
Setting the collector-distributor lane can increase traffic capacity of interchange with weaving section effectively. There is, by far, no uniform technical standard about designing the collector-distributor lane in our traffic specifications, which leads to an optional design about the collector-distributor lane. From the viewpoints on weaving section length, traffic in primary road and setting of the traffic signs, this paper discusses setting rules of the collector-distributor lane in interchange based on internal and external relative researches about weaving. According to the request of the interchange design and engineering instances, this paper puts forward the design methods of length, transect disposal and the lane separator about the collector-distributor lane, offering theoretical basis the detailed design of the collector-distributor lane.
