A traffic network can be viewed as a geometric graph with the nodes representing traffic
infrastructures and the edges standing for the links between these nodes. In order to reduce …

Previous studies on airport networks are strongly bounded time-wise or only conducted for
single networks at distinct levels of abstraction and for distinct topological features. Here, we …

COVID-19 is one of the most impactful pandemics in recent history, not only in terms of direct
casualties but also regarding socio-economic impact. The goal of our study is to investigate …

Complexity science is the multidisciplinary study of complex systems. Its marked network
orientation lends itself well to transport contexts. Key features of complexity science are …

Network theory has provided key insights into the overall resilience of air transportation
systems. We expand upon these insights by using Mahalanobis distance to quantify delay …

Airspace is a networked space that constantly changes in order to adapt with the changing
demand of air traffic. The goal of this research is to study the temporal evolution of the …

Air transportation systems are exposed to disruptions, which have significant impact on
operations. Airlines operate tight schedules to maximise resource utilisation, however, the …

In order to characterize the structural features of public transportation systems (PTSs) in
mountain cities, this paper systematically examines the robustness of urban transportation …

In this research, we propose a new methodology to assess structural similarity of air
navigation route systems in 58 countries. We identify functional dependencies among …

The agglomeration of airports into multi-airport regions (MARs) has become one of the
salient features of the worldwide air transport system in the last decades. Meanwhile, in …
