Intermodal competition and temporal interdependencies in passenger flows: Evidence from the emerald coast

Abstract

As travellers commonly perceive available transport modes (e.g. planes and ships) as substitutes, forcing transportation providers into competition for the same routes, this chapter analyses the effects of intermodal competition on the time series of passenger flows. Our conceptual framework suggests negative correlations of arrivals, both within and across transport modes, during low-season periods, and positive correlations during high-season periods. Using daily passenger arrivals at the airport and seaport of Olbia, from 2005 to 2008, and Threshold-VAR models to test these suggestions, the findings support our conceptual framework.
