Seattle drivers face fourth-worst congestion delays in the nation and spend an average of 83 hours a year stuck in traffic delays, a new study says.
The most-congested morning and evening commute in Seattle is Thursday, according to the fourth annual traffic index report by Tom Tom, the Dutch company that sells GPS navigation devices and other mapping products, including real-time traffic data. The least-congested morning commute is Friday and least-congested evening commute is Monday.
On average, Seattle drivers are delayed 34 minutes per hour during peak traffic periods.
Congestion also appears to get worse as the year progresses, and the most congested day last year was Nov. 7.

The report released Wednesday examines traffic congestion on local roads and city streets as well as highways and freeways.
Los Angeles drivers face the worst congestion in the nation and spend an average of 90 hours a year stuck in traffic delays, the study says. Los Angeles was followed by San Francisco and Honolulu.
For most U.S. cities, Thursday evening commutes have the worst congestion.
Tom Tom said its study, which used GPS-based measurements of traffic, compared travel times during peak periods of congestion with travel times measured when roads were flowing freely. The difference was expressed as an average percentage increase in travel time for each city.
For Los Angeles, the study found a 36% congestion level, followed by San Francisco, 32%, and Honolulu, 29%.
They were followed by Seattle, 27%; San Jose, 26%; New York, 26%; Miami, 24%; Washington, D.C., 24%; Portland, Ore., 22%; and New Orleans, 22%.
The least congested: Kansas City, 9%, and Indianapolis, 10%.
Looking at traffic overall in North and South America, the study found L.A. was fourth-most congested behind Rio de Janeiro, 55%; Mexico City, 54%; and Sao Paulo, 46%.
