Travel Demand
The graph below shows the most recent USDOT vehicle-travel data covering the last 25 years. Although vehicle-miles of travel (VMT) grew steadily during most of the Twentieth Century, in recent years the growth rate stopped and even declined a little. It is now about 10% below where it would have been had past trends continued.
Politicians and planners be warned: you will now be judged according to your ability to improve walking, cycling and public transit services.
