A bi-level airport choice model (BACM) in a multi-airport con-text. The case of Rome

In the last decade, the researchers’ interest in airport ground planning grew with the growth in the number of the air passengers. The aim of this paper is to set up a model of the airports’ competitiveness, considering the connections between airports and territory and the passengers’ perception of airports' services. We proposed a Bi-level Airport Choice Model (BACM) in a multi-airport context, able to find the best combination airport/transport mode from the users’ point of view, considering also the airport ground accessibility. We also drew a graphical user interface (GUI), where the users can insert the inputs relevant to their needs and visualize the result suggested by BACM. Finally, we have applied BACM to the case of Rome; the results underline the wide necessity to increase the connections to and from airports and reflect the current competitiveness between the considered airports.
