Vehicle Miles Traveled (VMT) can be defined as "One VMT is one car traveling one mile; 100 VMT = 100 Cars traveling One Mile or 50 Cars Traveling 2 Miles".


The number of vehicle miles traveled (VMT) is an indicator of the travel levels on the roadway system by motor vehicles. VMT is estimated for the given time period. On highways, a measurement of the total miles traveled in a given area for a specified time period. It is calculated by multiplying the number of vehicles by the miles traveled in a given area or on a given highway during the time period. In transit, it is calculated by multiplying the number of vehicles by the miles traveled on a given area or on a different route, line, or network during the time period. As Florida’s population continues to grow, VMT has grown at a rate higher than the national rate. However, the growth in population is not the only factor fueling the rise in travel. Other factors 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.

This indicator shows the annual percent change in DVMT (daily VMT) on Florida’s State Highway System. This data is analyzed from the Florida Department of Transportion's State Highway System Mileage Report. This is an annual indicator and is updated with a lag time of six to seven months.
