Although the number of daily miles logged by vehicles in the Bay Area declined during the Great Recession, daily miles traveled has spiked since 2010. The region has surpassed previous records for this indicator with vehicle miles traveled now totaling 172 million on a typical day. On a per-capita basis, daily travel in the Bay Area has stabilized since 2005 at approximately 23 miles per person. This suggests that recent growth in total mileage is primarily driven by population growth rather than longer travel distances.
At around 30 miles per resident, the North Bay counties of Marin and Solano had the highest average daily vehicle travel of the nine Bay Area counties in 2015. For Marin County, this figure represents a reduction from a daily VMT average that ran in the 30-plus range throughout the preceding decade. Conversely, at just 10 miles, San Francisco has by far the lowest VMT per capita.
