title = "Air traffic complexity: An input-output approach",
abstract = "There has been much effort to increase airspace capacity and one of the fundamental research problems is to measure the traffic complexity inside sectors. This paper proposes a new method for describing the air traffic complexity of a given traffic situation. We view the airspace as a closedloop input-output system and define air traffic complexity as {"}how difficult{"} a given traffic situation is, in terms of the control activity required to resolve it, in response to a change in {"}reference signal{"}, that is the presence of a new aircraft entering the airspace. We present a {"}complexity map{"} that offers a graphical view of the complexity for a given traffic situation. We also discuss how to extract a scalar measure of air traffic complexity from the complexity map. We illustrate our methodology with a few examples.",
