A new report from the Road Ecology Center at the University of California, Davis has found that total US vehicle miles traveled (VMT) at the county and state level have declined by 61% to 90% following the various government stay-at-home orders in response to the COVID-19 pandemic. Using data from StreetLight , the researchers estimated changes in daily vehicle miles traveled across the US before and after government shelter-in-place guidance. The difference amounted to a drop from 103 billion miles in early March to 29 billion miles during the second week of April. All states reduced their vehicle miles traveled by at least 60%. The authors used the VMT data to calculate that emissions of US greenhouse gas (GHG) emissions were reduced by 4% in total and by 13% from transportation in the almost 8 weeks since many stay-at-home orders went into effect. This puts the US on track […]
