中文摘要：

为了研究城市公共交通网络这一复杂网络的生成机理,以Space P法拓扑的公共交通网络为研究对象,结合公交网络设计中常考虑的公交线路和运营长度限制以及路网中公交站点的邻接矩阵等因素,从公共交通网络的初始网络、新增节点、新增节点的局域世界、优先连接概率及新增节点引起的连边五个方面进行分析,构造了公共交通网络的局域世界演化模型,并给出了适用于计算机编程的模型算法。采用该模型对西安市的公共交通网络进行了生成模拟,结果表明演化模型生成的网络与现状网络的累积度分布曲线、节点乘车次数分布极为接近,证明该模型反映了公共交通网络发展的基本规律。

英文摘要：

In order to study the generative mechanism of complex urban transit network,the local-world evolving network model of public transport was built on the basis of the network of transit network topologized by Space P method.The initial network,the new node,the new node＇s local-world,the probability of priority connections and the new node caused edges were analyzed from the public transport network designing constraint conditions which include the bus line length and bus stop adjacency matrix on the road network.For the application of the model,its computer programming model algorithm was given.By using the model,the generation of Xi＇an public transport network was simulated. The result shows that the cumulative degree distribution and riding times distribution of the network generated by the evolving network model is very similar to the existing public transport,which proves that the model reflects the basic law of the public transport network development.
