This new study by the Arizona DOT confirms the strong relationship between compact, transportation-efficient development and vehicular travel reduction. The study found that key drivers of travel reduction include density and compactness of land uses; diversity and mix of land uses; design of transportation with sidewalks; and destinations with easy access outside of the neighborhood, particularly jobs that can be reached by mass transit.
