从公交线网的生成机理看复杂网络的多样性

复杂网络的拓扑特征源于其内在的演化生成机制.通过对城市公交线网的多个静态特征指标的实证分析,给出了一个生成公交线网的计算机模拟模型,并验证了该模型的有效性.通过将公交线网与现有多种复杂网络进行比较,本文揭示了现实世界复杂网络的多样性,为复杂系统的网络拓扑性质的研究提供了新的视角.通过实证分析本文得出公交线网对于随机的网络节点删除表现出鲁棒性,而对于以最大度为目标的顶点删除表现出相当弱的鲁棒性;研究结论可以直接应用于公交枢纽站点的选址和公交网络的总体性能评价.

From urban transit networks to various complex networks

Topological properties of complex networks rise from their intrinsic growth mechanics.Through analyzing the static properties of real transit networks,this article puts forward a growth model to simulate transit network.The efficiency of the growth model is proved by an example.Comparing transit networks with other complex networks,this article manifests the real network's variety.A new angle of view is proposed in this article.Through analyzing the real transit networks,this article gets a conclusion that transit networks are robust against random vertex removal but considerably less robust to targeted removal of the highest-degree vertices.The research means of this article can be directly applied to determining the public transit hub and evaluating the performance of the whole transit network.
