Vehicle Miles Traveled, or VMT, is the sum of miles traveled byall vehicles on a specific segment of road within a period of time.VMT is calculated by multiplying the annual average daily traffic(AADT) volume for a specific segment of road - collected at trafficmonitoring stations - by the length of that road segment to derivethe total number of vehicle miles traveled on that road segmentannually. The calculated VMT estimates are then aggregated bycounty to provide an estimate of the percent change in VMT foreach county.This map depicts total VMT for each countyin Texas overlaid with oil & gas productionareas and shows a strong correlation betweenincreases in VMT and increased oil & gas activities.
