摘  要：
采用复杂网络的研究方法,建立交通复杂网络,针对度分布、度中心性指数、中介中心性指数、集聚系数等参数分析了常德市交通网络拓扑结构特征,揭示了交通网络结构的复杂性。研究结果表明:(1)从连接性来看,常德市交通网络度分布的累计概率呈现幂律分布的特点,常德市交通网络的连通性较好,但常德市下属各县市区的分布不均匀的特点。(2)从中心性来看,常德市各区域的群体中心性不算高,整体区域的中心性不是很均衡,度中心性指数与中介中心性的变异系数分别为0.742和0.447,在一定程度上反映了区域交通设施分布不均的情况。(3)从区域集聚性来看,整体集聚性偏低,常德市交通网络集聚数平均值为0.117,各县市区集聚系数值均小于0.3,故得出常德市交通网络集聚特征不明显,不具有小世界网络特征。

摘  要：
A complex network was built by using the method of complex network.Topologic structure properties of the traffic network in Changde city were analyzed through some index such as traffic distribution of node degree,degree central index,intermediary central index,clustering coefficient.The complexity of the traffic network was revealed.The studying results show that(1) Cumulative probability of traffic network degree distribution in Changde city followed the characteristic of power-law distribution,the connectivity of traffic network in Changde urban area is good,but that in intra-county were unbalanced.(2) The group centrality of Changde city was not high,the total regional centrality was not well balanced and the variation coefficients of degree centrality index and the intermediary central index were 0.742,0.447 respectively.To a certain extent,it reflected the unbalanced situation.(3) On the overall,the regional clustering was low.The average traffic network clustering value in Changde city was 0.117,the mean value was less than 0.300 in each countries of Changde city.Therefore,the traffic network clustering feature in Changde city was not obvious,did not have the characteristic of small world network.
