城市公交线路网络反映了整座城市的公共交通状况,通过对城市公交线路网络的研究,有利于发现城市公共交通中存在的问题,是提高城市公交运输能力的前提.从复杂网络的角度,分析比较了我国12座大中城市的公交线路网络的统计性质.定义了城市公交线路网络,基于该定义建立了12座城市的公交线路网络,对12座城市公交线路网络的度的取值、度的分布、权的分布、网络结点及边的介数分布进行了分析,得出了相关规律.%Public Transport Line Network(PTLN) reflects the whole city's public transport environment. According to the analysis of PTLN, the problem in public transport can be found easily, which is the base of the improvement of transport capacity. The network structure statistical characteristics of 12 cities in China are analyzed from the view of the Complex Network in this paper. First, the definition of the PTLN is given, based on which Public Transport Line Networks of 12 cities are built. Then the degree value, degree distribution, the distribution of network weight and the betweenness are analyzed. Based on these analyses, some potential rules in PTLN are found.
