中文摘要：
应用复杂网络的理论,结合统计得到的截止到2014年1月20日的成都市公共交通实际数据,构建邻接站点式的有向加权复杂网络,考虑上、下行线路（环线为内、外环）在站点布设和行车方向上的不同对网络拓扑特性的影响,对成都市公交网络的拓扑特性进行分析。结果表明,邻接站点式成都公交复杂网络节点平均度为2.52,节点强度分布不均,最大值达到45,平均节点强度为4.75,网络整体上服从幂律分布,具有较为明显的小世界特性。随着网络规模由成都市区向郊区扩张,网络平均最短路径长度由16.90增至34.19,增长明显。网络聚集系数0.14,体现出相对较高的公交路网发展水平。
英文摘要：
In order to analyzing the topological properties of public transport network in Chengdu,we gathered the data of the public transport by January 20 th,2014 and built the directed- weighted network in space- of- stations based on the theory of complex networks,and the differences between up- line and down- line（ inner ring and outer ring for circle line） on bus station arrangement and driving directions were considered. The results show that the average node degree of the network in space- of- stations in Chengdu is2. 52,and the node strength,with the maximum at 45 and average at 4. 75,performs an uneven distribution. The network follows the power- law distribution as a whole and has obvious small world property. With the expansion of the network size from urban area to suburbs,the average minimum path length of the network increases obviously from 16. 90 to 34. 19. The clustering coefficient is 0. 14,which reflects the high standard of the public traffic net relatively.
