Abstract
The air transportation network in a country has a great impact on the local, national and global economy. In this paper, we analyze the air transportation network in Brazil with complex network features to better understand its characteristics. In our analysis, we built networks composed either by national or by international flights. We also consider the network when both types of flights are put together. Interesting conclusions emerge from our analysis. For instance, Viracopos Airport (Campinas City) is the most central and connected airport on the national flights network. Any operational problem in this airport separates the Brazilian national network into six distinct subnetworks. Moreover, the Brazilian air transportation network exhibits small world characteristics and national connections network follows a power law distribution. Therefore, our analysis sheds light on the current Brazilian air transportation infrastructure, bringing a novel understanding that may help face the recent fast growth in the usage of the Brazilian transport network.
Highlights
Transport networks play an important role on the daily lives of populations
We focus our analysis on three scenarios that enable us to better characterize the Brazilian airport infrastructure, as well as to characterize the types of flights offered to the population
In this paper we analyzed the main topological characteristics of the Brazilian air transportation network, based on the set of national and international flights operated by the Brazilian airports
Summary
Brazil is an example of a country that has had an impressive growth in the usage of the air transportation network in the last 10 years. As the most of air transportation networks, the Brazilian network has a complex structure, with dozens of airports and airline companies, operating thousand of national and international flights. The overall analysis of the network enables the identification of the most important and central airports, as well as, the infrastructure robustness under airports fail due to, for instance, weather conditions It is not clear how the properties of the Brazilian air transportation network compare with other country networks. To the best of our knowledge, this is the first study that provides a deeper analysis of the Brazilian air transportation using a large number of complex networks features. Viracopos Airport (Campinas City) is the most connected and central airport in the national flights network, being part of a large number of shortest routes;.
