Seattle has retained its ignominious distinction: 4th-worst traffic in the country.
The TomTom Traffic Index reports that the nation’s worst traffic, as of spring 2013, is in Los Angeles followed by San Francisco and Honolulu.
When you include all of North and South America, Los Angeles ranks below Rio de Janeiro, Sao Paulo, and our friends to the north in Vancouver, B.C.
Portland broke into the U.S. top 10 with the eighth-worst traffic, ahead of Boston and Chicago.
Seattle and Portland’s congestion patterns show that Thursday is the worst day of the week to commute, both morning and evenings. Traffic is lightest on Friday mornings and Monday evenings.
Looking for a city in the Western states with relatively low congestion? Head for Salt Lake City, No. 53, or Phoenix, No. 56. The least-congested city in the nation is Indianapolis. Read The Seattle Times story and the TomTom report it cites.
