Air Traffic Complexity: An Input-Output Approach

Applying Airspace Capacity Estimation Models to the Airspace of Hungary

“…the distribution of aircraft in the airspace and their speed and direction related to each other) and those that model air traffic as a dynamic system and represent it with one characteristic system variable (Delahaye and Puechmorel, 2000). Another example of such simplified models is the "complexity map" model, that is also based on the geometry of air traffic and provides values of the necessary change of aircraft direction and velocity (thus giving the approximate level of controller workload) as a function of the position and flight direction of new aircraft entering the airspace (Lee et al, 2007).…”

A Dynamic I/O Model for TRACON Traffic Management

“…Letting more planes entering the TRACON leads to reroute them. This increases the TRACON controller workload, increase the density of aircrafts and the airspace complexity [11] and decreases the degrees of freedom for rerouting. An certain amount of planes is required to reach the maximum capacity of landings, but over it, it decreases the safety and does not improve performances.…”

“…The system is hence very often degraded. The complexity [11] of the system must remain under a certain level so that if a degradation is to happen, the safety is still assured. A way to reduce complexity is to limit the number of aircrafts present in the system.…”

Modelling of marine traffic flow complexity

“…From the most air traffic complexity definitions (Xing and Manning, 2005;Lee, 2007Lee, , 2008, the main purpose of air traffic complexity researches is evaluating the traffic controllers' workload. While in this paper, marine traffic complexity is employed to describe the traffic situation, focuses on digging the traffic data (like: vessel locations and motions) and provide the traffic information which can be used to support the decision making.…”
