Visualizing the Accessibility by Air (AbA): Examples for Urban Destinations in Europe

by M. M. Felber, J. A. Mazanec, & J. Wöckl

A major competitive advantage of a destination is its accessibility by air. Cities and airports are advised to carefully monitor the airlines’ flight schedules that will be reflected in the passengers’ perceptions of reachability. An AbA Index is constructed for 219 European destinations and 15 departure airports. The Index is based on the travelers’ combined flight and waiting time. The information hidden in the 219-by-15 matrix is subjected to data compression and visualization. Self-Organizing Maps are used for condensing the accessibility information into a two-dimensional array that portrays the density of flight connections offered by a particular airport.
