Methodologies Used to Estimate and Forecast Vehicle Miles Traveled (VMT)
Texas A&M Transportation Institute: Vehicle miles traveled (VMT) is a measure used in transportation planning for a variety of purposes. It measures the amount of travel for all vehicles in a geographic region over a given period of time, typically a one year period. VMT is calculated by adding up all the miles driven by all the cars and trucks on all the roadways in a region. This metric plays an integral role in the transportation planning, policy making, and revenue estimation processes due to its ability to indicate travel demand and behavior.
