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 data base, 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. On the basis of these elasticities it then assessed the impact of the Bronx Center Project on travel patterns and trends.

A second project, "Accessibility Indicators and Local Employment," hypothesized that labor force participation is affected, among other things, by the level of accessibility to employment locations. Specifically, it conjectured that improved accessibility in a given area, resulting from transportation infrastructure investment, will enhance labor participation, given intervening factors such as socioeconomic and locational characteristics. It further conjectured that this effect will be more pronounced in low-income areas where costs of labor-market participation, including transportation costs, constitute a real barrier to market entry. Using a simultaneous equation model, this paper empirically explored the impact of accessibility changes on the supply of labor in specific job types in the South Bronx, New York, an economically distressed area. The major sources of data for this study were three U.S. Census Bureau data files from the 1990 Census Transportation Planning Package.
