本研究利用经验证据和基于该数据的模拟模型，探讨了地面运输网络的拓扑演化。进化是一个相互作用、投资和撤资的迭代过程。还使用连通性、密度、异质性、集中度和连接模式的度量来评估网络的拓扑属性的时间变化。该仿真模型使用印第安纳州城际网络的历史数据进行了验证。统计分析表明，该仿真模型能够很好地预测城际网络中链路的丢弃顺序以及拓扑属性的时间变化。然后将该仿真模型应用于不同的理想化网络结构。网络中出现了环状、网状、轴辐状和死胡同等典型的连接模式：网络层次的自发组织、平行链路之间的间距的时间变化以及位置的相对重要性的起伏，为地面交通网络的自组织特性提供了进一步的证据。(C)2008爱思唯尔有限公司。保留所有权利。
This study explores the topological evolution of surface transportation networks, using empirical evidence and a simulation model validated on that data. Evolution is an iterative process of interaction, investment, and disinvestment. The temporal change of topological attributes for the network is also evaluated using measures of connectivity, density, heterogeneity, concentration, and connection Patterns. The simulation model is validated using historical data from the Indiana interurban network. Statistical analyses suggest that the simulation model performs well in predicting the sequence of link abandonment in the interurban network as well as the temporal change of topological attributes. The simulation model is then applied on different idealized network structures. Typical connection patterns such as rings, webs, hub-and-spokes, and cul-de-sacs emerge in the networks: the spontaneous organization of network hierarchies, the temporal change of spacing between parallel links, and the rise-and-fall of places in terms of their relative importance are also observed, providing further evidence for the self-organization property of surface transportation networks.
