National transportation policy faces a number of urgent imperatives, including mitigation of air pollution and greenhouse gas production, and coping with congestion in the face of constrained capacity to construct and expand roadways. Because of these concerns, research into the interaction of land use and transportation policy has focused on the capacity of alternative land use approaches--including transit villages, New Urbanist development, jobs-housing balance, and compact development in general--to moderate growth in vehicle miles traveled (VMT). These development forms are referred to collectively in this study as "alternative" development.
