Insights on the Determinants of Walk Trips Using Large Scale Travel Survey Data

The purpose of this research is to contribute to the body of knowledge on the determinants of walk trips in urban areas using individual data from a large-scale travel survey data. The main purpose of this research is to identify features that can have an influence on the individual decision to walk to travel short distances (less than 1.6 km). Benefiting from the availability of microdata from a large-scale travel survey (2003, sample of some 60,000 households), a study of short trips is conducted for people living in more than sixty districts of the Montreal Area. Walk trip shares are estimated as well as a set of variable describing urban structure (population density, tortuosity of the trip on the road network, intersection density). Using these variables as well as the individual and households attributes, a model describing mode choice for short trips, is estimated at the individual level.
