Notes on methodology: StreetLight’s VMT Monitor provides our estimate of total vehicle miles travelled (VMT) by residents of each county, each day since the COVID-19 crisis began, as well as a change from the “baseline.” We define baseline as the average daily VMT of the most recently processed month in our online portal.

CSV access: The downloadable VMT Monitor CSV file is composed of daily VMT figures for all mapped counties, from January 1, 2020 through August 17, 2021.
