城市道路网络社团结构的识别与分析

Finding and analyzing community structure in urban road network

社团结构是复杂网络具有的一项重要性质,为探究不同城市路网社团结构的特点,本文利用分裂算法,对北京、成都、南京、武汉4个城市的路网进行社团结构划分,分析路网空间结构与社团结构之间的联系。实验结果表明,城市路网有着较强的社团特性,网络模块度最大值高于一般社会网络,同时路网社团结构可以较好地识别出一些路网中联系紧密的区域。本文在路网结构研究中引入社团结构概念,进行了新的尝试,并且取得了有益的成果。

Community structure is an important property of complex networks.In order to explore the characteristics of the community structure of road networks in different cities,this paper used the split algorithm to divide the community structure of road networks in four cities,including Beijing,Chengdu,Nanjing,and Wuhan to analyze the road networks and the connection between cyberspace structure and community structure.The experimental results showed that the urban road network had strong community characteristics,and themaximum network modularity was higher than that of the general social network.At the same time,the community structure of the road network can better identify some closely connected areas in the road network.In this paper,the concept of community structure was introduced in the research of road network structure,a new attempt was carried out to obtain beneficial results.
