摘　　要：快速路网中的节点功能定位是否恰当、立交选型是否合理 ,是能否实现快速路交通特性的重要因素。本文从北京市快速道路系统中的节点现状分析 ,提出节点存在的问题 ,采用“最短路径法”,对快速道路系统中的节点进行功能定位 ,并对今后快速道路系统中节点的建设与改造 。Whether the node function location of the express road network is appropriate or not and whether the selection of the interchange types is reasonable or not is the important factors whether it achieves the traffic characteristics of the express roads. According to the analysis of the present situation of the nodes in the express road system in Beijing City, the paper puts forward the existing node problem and uses 'the shortest road path method' for the node function position in the express road system, and provides the principle and thought in the next node construction and reformation in the express road system for guidance.
