摘要
公路网的连通度评价指标反映了网络中各节点的连通状况,体现了网络的结构特征。在分析现有的公路网连通性评价指标的基础上,考虑到道路通行能力对公路网连通度的重要影响,提出公路网连通性评价指标的新定义。最后给出计算示例,说明该方法的有效性。
The evaluating index of highway network connectivity reflects connecting status of each nodes in the network, and shows the structural characteristics of the network. Based on the analysis of the existing evaluating index of highway network connectivity, taking into account the important impact of the road capacity on the connectivity of road network, a new definition is given in this paper. Finally, a calculation example is presented to explain effectiveness of the method.
