Vehicle Miles Traveled Information
The number of vehicle miles traveled (VMT) is an indicator of the travel levels on the roadway system by motor vehicles. VMT is estimated by calculating the number of vehicles by the miles traveled in a given area or on a given highway during a given time period. As Florida’s population continues to grow, VMT has grown at a rate higher than the national rate. Factors of VMT growth include economic growth, relatively affordable auto travel costs, tourism, low levels of public transit, sprawl, and related factors. As the amount of auto travel increases, the time wasted on congested roadways, the energy used by the vehicles, and total costs of auto travel increase accordingly.
