基于复杂网络的公交网络特性研究

Study on Public Transport Networks Characteristics Based on Complex Networks

为了有效的控制城市交通网络的平衡,合理的配置公交线路及任务,采用复杂网络的研究方法,以泰安市公交网络为研究对象,参考图论的定义,把公交停靠站点抽象为节点,站点之间的连线抽象为边,主要通过Space L和Space P方法建立公交网络,通过实证研究分析其复杂网络特性。数据分析说明泰安市公交网络平均路径长度较大、聚类系数较小,与其他城市相比不具有小世界网络特性,因此对存在的问题提出了参考方案,数据分析表明应用复杂网络理论解决公交复杂网络问题是可行的。

In order to control the urban transport networks balance effectively and assign the bus lines and tasks rationally,we extracted the bus stops into the nodes and the links between stops into the edges by adopting research methods for complex networks with transport networks of taian city as a study example to set up a transport network with Space L and Space P after referring to graph theory definition,so that the complex networks characteristics were analyzed through empirical study.The results show that the taian transport complex networks have the big average path length and small cluster coefficient,which is different with other cities with characteristics of the small-world networks.Therefore,a reference scheme for the above problems was proposed.The practice analysis proves that it is feasible to solve the transport networks difficulty by the complex networks theory.
