Modeling Participation and Consumption in the Greek Interurban Public Transportation Market

This article investigates the Greek household travel demand for domestic interurban public transportation using cross-sectional micro-data from a countrywide Household Budget Survey. A number of limited dependent variable models, including the Heckit, Two-Part, and Double-Hurdle models, are implemented to jointly estimate the probability of selecting a specific mode and the amount of using it. The results provide useful insight into the existence of feedback relationships between the decision- making mechanisms of mode selection and amount of usage, and they demonstrate the predominant effect of income on the demand for coaches, railways, airplanes, and coast-wise sea ferries
