Vehicle Miles Traveled per person continues to decline in region

Although larger population means 1.2% higher VMT over last year

Daily vehicle miles traveled (VMT) in the central Puget Sound region totaled 88.4 million, an increase of 1.2% between 2017 and 2018. While total VMT saw a slight increase, the daily VMT per person in the region decreased 0.5% between 2017-2018.

From 2010 to 2018, daily vehicle miles in the region grew at a much slower rate than population or employment. As VMT grew by 6%, population grew by 12% and employment by 22%. Transit boardings in the region increased 20% during this period.

Since 2010, the daily VMT per person has decreased 5% which is significant in the context of increasing population and employment in the region. The 2018 estimate of 21.4 miles daily VMT is well below the peak of 24 miles per person per day in the late 1990s.

Around the region Snohomish County had the lowest increase in VMT between 2017 and 2018 at 1%. Both King County and Pierce County saw a 1.2% increase, while Kitsap County saw a 2% increase in total VMT during the same time period.

Statewide, VMT has been on par with population growth.

You should not take much credit for lowering vehicle miles. The major reason is that driving in the metro region is such a miserable experience. Driving back and forth from Seattle to Tacoma almost any time of day is such a terrible, mind numbing experience it is to be avoided at all costs. Making driving such a horrible experience cannot be considered a success.

The previous comment fails to note the smallest increases are not in the area he cites. Also that PSRC does not claim any credit.
PSRC does a great job assessing the data and coordinating policy.
