Vehicle miles of travel (VMT)

Most traffic counts are reported in terms of annual average daily traffic (AADT) and represent an estimate of the number of vehicles traveling along a given point on a highway on an average day in the year. Vehicle miles of travel (VMT) estimates, while based on AADT estimates, include the distance traveled element and thus provide a measure of highway vehicle travel usage over a geographic area, such as a county, state, or highway system. VMT estimates also serve as the denominator in calculating crash and fatality rates for measuring highway safety.

All vehicle miles of travel (VMT) reports are in Adobe PDF PDF format.
