中文摘要：

通过网络机器人搜集了杭州公交网络的真实数据,分别用space L、space P和space R 3种方法对其进行建模.随后分析其基本网络统计特性,包括平均最短路径、平均聚类系数和度分布,并且分析了其两个特殊网络统计特性：社团特性和传播特性.通过对公交网络特性的详细分析得到,公交网络是一个具有指数型度分布、明显社团结构和较强传播能力的小世界网络.

英文摘要：

Bus transport network（BTN） is a typical complex network.The practical data of BTN of Hangzhou City are collected by network robot.The BTN is modeled by space L,space P and space R methods respectively.Then the basic network characteristics of these models including average shortest paths,average clustering coefficient and degree distribution are analyzed.Two special network characteristics called community structure and epidemic spreading are analyzed farther.By the detailed analysis of the BTN,we get the conclusions that bus transport network is a small-world network which has an exponential degree distribution,obvious community structure and strong epidemic spreading capability.
