Statistical Characteristics and Community analysis of Urban Road Networks

Wen-Long Shang, Huibo Bi, Yanyan Chen, Washington Ochieng

摘要:

城市道路网是典型的复杂系统,对社会经济发展具有重要的意义。在这项研究中,一些纯粹的物理道路,而不是车辆或巴士路线的基础上的城市道路网络的拓扑特征进行了研究,以发现潜在的独特的结构特征,特别是与其他类型的交通网络。基于这些拓扑指数,城市道路网络的拓扑指数和小世界之间的关系进行了探讨。研究结果表明,城市道路网络不存在显著的小世界性,这与其他交通网络有明显的不同。在此基础上,进行了城市道路网络的社区检测。研究结果表明,城市道路网络的群落结构和层次结构具有一定的规律性。

英文摘要:

Urban road networks are typical complex systems, which are crucial to our society and economy. In this study, topological characteristics of a number of urban road networks based on purely physical roads rather than routes of vehicles or buses are investigated in order to discover underlying unique structural features, particularly compared to other types of transport networks. Based on these topological indices, correlations between topological indices and small-worldness of urban road networks are also explored. The finding shows that there is no significant small-worldness for urban road networks, which is apparently different from other transport networks. Following this, community detection of urban road networks is conducted. The results reveal that communities and hierarchy of urban road networks tend to follow a general nature rule.
