The Washington State Department of Transportation’s (WSDOT) 2015 “Corridor Capacity Report” is out today. It takes a sweeping view of transportation system usage statewide, including some of the state’s worst congestion points.

You can read media coverage of the report in The Seattle Times, The News Tribune, and at MyNorthwest.com.

Here are some of the highlights:

• “Although statewide traffic congestion (vehicle hours of delay) has been on an upward trajectory for the past five years, 2014 annual congestion (32.3 million hours) remained 8% below the 2007 pre-recession levels (35.1 million hours). The central Puget Sound region did not follow this 2014 trend and congestion there was 19% higher than pre-recession levels.”
• The Central Puget Sound region accounted for 90.4% of statewide hours of traffic delay in 2014; South Puget Sound, 5.0%; Vancouver0.6%; Tri-Cities, 0.5%; and Spokane, 0.4%.
• Total vehicle miles traveled (TMV) rose 2.6% from 2012 to 2014, but measured per-person, TMV only went up 0.4%.
• “The statewide congestion indicator – vehicle hours of delay – increased 4.6% statewide between 2012 and 2014, mirroring the growth in the state’s economy.”

There’s a lot more data in the report and an accompanying interactive online tool.
