  • The total cost of regional traffic congestion in 2011 was $2.24 billion.
  • Peak-travel-hour drivers in metropolitan King County who need to arrive at their destinations on time should quadruple their estimates for travel time, compared to what the same trip would take during light-traffic hours.

"So we share a car, for the entire family. I’m generally the bus rider, and I live in Seattle, where public transportation is decent.  So this is helpful, because I can either walk to work or walk home or take the bus, but the bus is getting expensive!… They don’t have it covered at work, like a benefit. That would be super helpful."
