| 摘 要： | 运用复杂网络理论的研究方法,分析了青岛市公交线路网络的性质。以交通网络中的停靠站点为研究对象,建立了公交换乘网络,计算了网络的度分布、聚集系数、平均路径长度等拓扑参数,发现传统的聚集系数不能很好表现网络的聚集程度,指出节点的聚集系数与通过该节点的公交线路数目呈反相关关系。

Complexity Analysis on Public Transport Network |
| |
| Abstract: | Public transport network reflects the whole city＇s public transport environment,the geometrical property of which plays an im-portant role on the public transportation.In this paper,the theory of complex network is applied to study the public transport network of Qingdao.Then the bus change network is constructed based on the stops.In order to study this network,some calculations are made to get topology such as degree distribution,clustering coefficient,average path length and so on.It is found that clustering coefficient couldn＇t make clear the density of the network and it has negative corelation with the numbers of the bus line passed that stop.From the result it is concluded that the public transport network of Qingdao is a connected network with a rather samll average path length and a big clustering coefficient and its degree distribution follows exponential distribution.All of these prove that the Qingdao public transport network has the small-word property and Qingdao＇s Public Transportation is rather convenient. |
