Ground-Air Traffic Congestion Propagation Model Based on Hierarchical Control Interdependent Network

Abstract

A multilayer network approach to model and analyze air traffic networks is proposed. These networks are viewed as complex systems with interactions between airports, airspaces, procedures, and air traffic flows (ATFs). A topology-based airport-airspace network and a flight trajectory network are developed to represent critical physical and operational characteristics. A multilayer traffic flow network and an interrelated traffic congestion propagation network are also formulated to represent the ATF connection and congestion propagation dynamics, respectively. Furthermore, a set of analytical metrics, including those of airport surface (AS), terminal controlled airspace (TCA), and area-controlled airspace (ACA), is introduced and applied to a case study in central and south-eastern China. The empirical results show the existence of a fundamental diagram of the airport, terminal, and intersections of air routes. Moreover, the dynamics and underlying mechanisms of congestion propagation through the AS-TCA-ACA network are revealed and interpreted using the classical susceptible-infectious-removed model in a hierarchical network. Finally, a high propagation probability among adjacent terminals and a high recovery probability are identified at the network system level. This study provides analytical tools for comprehending the complex interactions among air traffic systems and identifies future developments and automation of layered coupled air traffic management systems.

Optimal Sequencing of Arrival Flights at Metroplex Airports: A Study on Shared Waypoints Based on Path Selection and Rolling Horizon Control

“…However, the operation of these airport clusters, which are also known as "airport metroplex", is coupled and complex, largely due to their co-location within the same terminal area airspace [1][2][3]. The mutual influence among these airports and their shared use of airspace resources inevitably lead to lower operational efficiency [4][5][6][7].…”

Epidemic Intelligence Models in Air Traffic Networks for Understanding the Dynamics in Disease Spread - A Case Study

“…This information is invaluable for designing targeted interventions, implementing travel restrictions, and optimizing screening measures at airports. Jiang et al (2023), as well as Pastor-Satorras and Vespignani (2002), identified the SIS model when applied to air traffic networks that allow individuals to transition between susceptible and infectious states multiple times, reflecting the continuous exposure and recovery patterns observed in real-world scenarios. This model enables the investigation of the potential for recurrent outbreaks within air travel networks.…”
