摘　　要：立交是城市道路网络系统的关键节点,随着城市交通需求增长和城市开发建设拓展,部分已建城市立交出现了功能定位、转向关系或交织能力不相匹配等问题。需要通过转移路网需求、定向提升能力、完善交通组织等分流节点流量或提升通行能力,以青岛流亭互通为例,研究立交改造方案及实施效果。Interchange is a key node of urban road network system.With the growth of urban traffic demand and the expansion of urban development and construction,the built urban interchanges often have problems such as the functional orientation,turning relationship or interweaving capacity mismatch.It needs to be improved by transferring the demand of road network,directionally improving the capacity,perfecting the traffic organization,separating the node flow or upgrading the traffic capacity.Taking Qingdao Liuting Interchange as an example,the reconstruction scheme and implementation effect of the interchange are studied.

关 键 词：立交改造 节点功能 转换关系 交织能力
