Performance Of Regional Transportation Systems Compared
"The United States invests billions of dollars annually into the nation's transportation systems. Getting the most from this investment requires an understanding of the impacts that different investments have on transportation performance, environmental protection, and consumer transportation choices. EPAs new study, Characteristics and Performance of Regional Transportation Systems begins to address these issues... The study found that:In four of the five size groups, the regions that have more route choices, better pedestrian environments, and more transit availability, also exhibit lower vehicle miles of travel per capita, shorter vehicle trip length, less congestion, more transit trips and fewer emissions compared to their peers. In one group the two cities were essentially tied."
