The number of vehicle miles traveled (VMT) in the United States and the U.S. gross domestic product (GDP) grew at the same rate from 1960 to 1997 (3.5% average annual growth). After that time, GDP growth outpaced VMT – average annual growth in GDP of 2.1%, compared to 1% for VMT. Despite increases in VMT from 2011-on, the gap between GDP and VMT is the largest in 2017. There are many causes contributing to this trend such as societal and work organization changes, technology adoption, and growth of economic activity that does not increase travel (e.g., software development, banking industry). Going forward, VMT may be constrained by infrastructure capacity, while GDP is not.
