摘　　要：城市公交系统在城市交通中具有重要作用,城市公交网络的静态特性对公交系统的性能具有重要影响。针对镇江公交特点,采用公交站点网络(Space L)方法对镇江公交网络建模,通过计算节点度、路径长度和聚集系数及其分布规律,分析镇江公交网络的静态特性。结果表明,镇江公交站点网络节点度分布服从指数分布,平均路径长度为14.901 9,平均聚集系数为0.103 9,具有明显的小世界网络特性。Urban public transportation system is important in urban transportation. The static characteristics of the network have an important effect on the capability of the public transportation system of a city. According to the characteristics of the of public transportation of Zhenjiang, the Space L network of the public transportation of Zhen- jiang network is established. By the computation of the degree distribution, path length, and network clustering co- efficient, complex characteristics of a public transportation system of Zhenjiang are studied. The result indicates that the degree distribution of the network follows a exponent distribution, and the average path length is 14. 9019, the network clustering coefficient is 0. 1039. It is proved that the public traffic network of Zhenjiang city has the small-world properties.
