摘　　要：为分析沈山高速公路局域路网交通状况及特性,从图论和复杂网络理论出发,基于拓扑结构理论,建立辽宁省沈山高速路网的拓扑结构,同时采用区域路网基本容量模型和区域路网极限容量模型对局域路网承载能力和运营风险饱和度进行分析,为沈山高速公路改扩建路网分流提供数据参考。In order to analyze the traffic conditions and characteristics of the local road network of Shenshan expressway,starting from the graph theory and complex network theory,based on the topology structure theory,the topology structure of the road network of Shenshan expressway in Liaoning province is established.At the same time,the carrying capacity and operational risk saturation of the local road network are analyzed by using the basic capacity model and ultimate capacity model of the regional road network,so as to provide data reference for the diversion of the reconstruction and expansion road network of Shenshan expressway.
