Transportation infrastructure plays an important role in supporting the national economy and
social well-being. Extreme events have caused terrible physical damages to the …

Aviation is a complex system with different interconnected and interdependent subsystems
that rely on each other to ensure safety and reliability. The technological progress in the …

To better understand the mechanism of flight delay propagation at the system-level, we built
a delay causality network (DCN) based on the Granger causality test. Through topological …

In the air traffic control (ATC) system, delays are tightly coupled among airports.
Understanding the interactions of these delays is a prerequisite for accurate prediction …

Air transport systems are highly dynamic at temporal scales from minutes to years. This
dynamic behavior not only characterizes the evolution of the system but also affect the …

Air traffic networks are highly dependent on airport arrival processes, which are common
triggers for capacity constraints and delay propagation. Arrival Manager tools aim to improve …

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 …

The rapid increase in the number of unmanned aerial vehicles (UAVs) poses a threat to the
safety of personnel, ground facilities, and aircraft. Therefore, as the basis of UAV safety …

The COVID‐19 global pandemic hit the aviation industry hard since the end of 2019. It has
had an immediate, dramatic impact on airport traffic and revenue. Airports are the important …

We formulate and implement a new metric for identifying multiple airport regions (MARs)
around the world, based on the temporal distance between airports. This metric, opposed to …
