Abstract

The 21st IEEE International Conference on Intelligent Transportation Systems, Maui - Hawaï, Etats-Unis, 04-/11/2018 - 07/11/2018; The continuous increase in air traffic is pressuring airport operators to augment their capacity while still complying with safety regulations. To achieve this goal, operators need a thorough knowledge of how the airport surface is put to use (i.e., how aircraft are routed) under various conditions. We propose an approach to characterizing traffic in an airport from radar-collected aircraft ground trajectories. The approach does not require prior knowledge of the airport's topology (since it reconstructs it from the available data) and uses network constrained trajectory clustering to produce groups of similar trajectories that represent frequently traveled routes in the airport. Our main findings from experimental results on real data from the Paris-Charles-de-Gaulle airport (France) indicate that the retrieved routes are highly linked to exploitation constraints (maneuver undertaken by the aircraft, runway, and configuration) and that the approach can help uncover the existence of less traveled alternative routes that can be useful for rerouting purposes.

Abstract

This article provides jet fuel demand projections at the worldwide level and for eight geographical zones until 2025. Air traffic forecasts are performed using dynamic panel-data econometrics. Then, the conversion of air traffic projections into quantities of jet fuel is accomplished by using a complementary approach to the 'Traffic Efficiency' method developed previously by the UK Department of Trade and Industry to support the Intergovernmental Panel on Climate Change (IPCC, 1999). According to our main scenario, air traffic should increase by about 100% between 2008 and 2025 at the world level, corresponding to a yearly average growth rate of 4.7%. World jet fuel demand is expected to increase by about 38% during the same period, corresponding to a yearly average growth rate of 1.9% per year. According to these results, energy efficiency improvements allow reducing the effect of air traffic rise on the increase in jet fuel demand, but do not annihilate it. Jet fuel demand is thus unlikely to diminish unless there is a radical technological shift, or air travel demand is restricted.
