This series of projects examined travel behavior and accessibility in the Bronx. The first study in the series, "The Implications of Travel Profiles for Transportation Investment," analyzed travel conditions and choices in the Bronx, where large-scale transportation and other development projects were presently taking place. Using a large database composed of census tract information on socio-economic and travel behavior, the paper first examined the travel profile of the Bronx population, by estimating travel choice elasticities.
