巴西机场网络的结构演变
Structural Evolution of the Brazilian Airport Network
摘要：
航空业是有利可图的，但对经济波动、地缘政治限制和政府法规很敏感。至于其他交通工具，出发地和目的地之间的关系导致路线图复杂，可以用与路线本身有关的信息，例如频率、交通负荷或距离来补充。网络理论提供了一个自然的框架来研究由此产生的结构上的动力学。在这里，我们调查的结构和演变的巴西机场网络（BAN）的几个数量：航线，连接，乘客和货物。一些结构特征与其他机场网络的研究结果一致。对BAN演变的分析表明，其结构是动态的，一些机场和航线的相对相关性发生了变化。结果表明，连接收敛到特定的路线。该网络在路线层面上缩小，但乘客数量和货物数量增加，在研究期间增加了一倍以上。
英文摘要：
The aviation sector is profitable, but sensitive to economic fluctuations, geopolitical constraints and governmental regulations. As for other means of transportation, the relation between origin and destination results in a complex map of routes, which can be complemented by information associated to the routes themselves, for instance, frequency, traffic load or distance. The theory of networks provides a natural framework to investigate dynamics on the resulting structure. Here, we investigate the structure and evolution of the Brazilian Airport Network (BAN) for several quantities: routes, connections, passengers and cargo. Some structural features are in accordance with previous results of other airport networks. The analysis of the evolution of the BAN shows that its structure is dynamic, with changes in the relative relevance of some airports and routes. The results indicate that the connections converge to specific routes. The network shrinks at the route level but grows in number of passengers and amount of cargo, which more than doubled during the period studied.
