复杂公交网络模型的构建和统计特性分析

Model construction and statistical characteristics analysis of complexpublic transit network

为了控制城市交通拥堵,优化城市公交网络,选取了截止2017年6月宝鸡市区406个站点、51条公交线路的样本数据。采用复杂网络的方法构建了宝鸡市公交网络模型,分析了宝鸡市公交网络的度分布、聚类系数、平均路径长度和介数等统计特性。通过分析得到:宝鸡市公交站点网络是一个具有幂律分布、小世界的复杂网络。度最大节点和介数最大节点对改善公交网络,控制交通拥堵至关重要。

To control the traffic congestionof Baoji and improve the public transit network,by collecting the sample data of 406 stations and 51 bus routes in the city of Baoji until June 2017,the complex network model was constructed based on the complex network theory.The statistical propertieson degree distribution,clustering coefficient,average shortest path length and betweenness are analyzed.Through the analysis,the conclusion is drawn that the public transit network of Baoji is a complex network with power-law distribution,small world.The node with the largest degree and the largest betweenness is very important for the control the traffic congestionof Baoji and improvement of the public transit network.
