Traffic around Seattle is bad and getting worse. Solutions are scarce. But a groundbreaking local study — now a decade old — and the experience of other cities may point toward a remedy, albeit an unpopular one: Pay to use the roads.
Nearly 15 years ago, a local transportation planning agency tried a novel experiment.

Traffic Lab is a Seattle Times project that digs into the region’s thorny transportation issues, spotlights promising approaches to easing gridlock, and helps readers find the best ways to get around. It is funded with the help of community sponsors Alaska Airlines, CenturyLink, Kemper Development Co., Sabey Corp., Seattle Children’s hospital and Ste. Michelle Wine Estates. Seattle Times editors and reporters operate independently of our funders and maintain editorial control over Traffic Lab content.

Another said, “Even if the meter wasn’t there, I would have changed my travel habits after seeing the first invoice.”
The study, conducted by the Puget Sound Regional Council (PSRC), found…
