U.S. HIGHWAY VEHICLE MILES TRAVELED
Highway Vehicle Miles Traveled (monthly data, with underlying trend)
Vehicle miles of travel (VMT) are key data for highway planning and management,
and a common measure of roadway use. Along with other data, VMT are often
used in estimating congestion, air quality, and potential gas tax revenues,
and can provide a general measure of the level of the nation’s economic
activity.
| Millions of highway miles |
240,290 |
243,960 |
| Vehicle miles percent change from same month previous year |
-1.16 |
1.53 |
NOTE: The current value is compared to the value from the same period
in the previous year to account for seasonality. A trendline has been
provided for vehicle miles traveled. The trend has been calculated through
a statistical procedure called Structural Modeling, in which the time
series under study is decomposed into seasonal, trend and irregular components.
For further information on this statistical procedure, see: S.J. Koopman,
