Vehicle Miles Traveled
Vehicle miles traveled (VMT) measures the amount of travel for all vehicles in a geographic region over a given period of time. 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.
Travel on Florida’s State Highway System (SHS) has been steadily increasing since 2014. Between 2014 and 2018, vehicle miles traveled on Florida’s SHS during the peak hour increased by 16.3%.
