Vehicle miles traveled are FHWA estimates built from about 5,000 continuous traffic counting stations that states operate, expanded to all public roads. The latest month is preliminary and is revised in the next month's report; percent changes compare the same month a year earlier. Where a state reported no stations, FHWA estimates its travel from nearby states or the national trend.
