Study: Los Angeles traffic most congested in US

TomTom uses anonymous GPS data to pick the metro areas with the worst gridlock.

If you have to drive daily in Boston or Detroit, Tuesdays and Thursdays are your best days to stay off the roads. And if you live in Los Angeles, you may want to consider telecommuting, according to the TomTom North American Congestion Index.


The company's newly released study, based on millions of real-time driving patterns gathered anonymously from its mobile navigation customers, ranks Los Angeles as the city with the worst road-rage-inducing traffic in North America. Tailgating LA in the study are Houston, San Francisco and Minneapolis, three cities that TomTom tagged as having the fastest-growing gridlock.


The TomTom index, a comprehensive, data-driven study of the clogged streets in major cities, ranks traffic levels in more than 50 cities and analyzes traffic flow at different times of the day and on different days of the week, as well as around specific events.


It’s not the only study of this type to single out LA’s freeways as a commuter’s nightmare.

Drawing on five years of trend data, Inrix’s 2011 Traffic Scorecard corroborated TomTom’s crowning of LA as the country's bad-traffic champion. The Seattle-based provider of traffic data and services identified a 13-mile stretch of Interstate 405 in LA as the worst traffic corridor in the country, averaging 20 minutes of daily delay. Inrix pinpoints Thursdays from 5:45 p.m. to 6:00 p.m. as the worst day and time to be on any freeway in LA, although we would say it’s more like 5:45 a.m. to 6 p.m.


Its not all bad news for urban drivers. Although Inrix says U.S. commuters wasted an average of 12 hours in traffic within the last 12 months, the company found congestion actually dropped 27 percent last year compared with 2010, reflecting the crawling U.S. economy. If that still sound like a long time, you can take some comfort while stuck in traffic knowing that commuters in Canada are stuck for a whopping 29 hours in traffic during the past 12 months. The Canadian cities of Vancouver, Montreal and Toronto ranked in the top five of the TomTom study, along with LA and San Francisco.

Traffic in Seattle SUCKS !   Inept drivers for one,  water and mountains on both sides as factor two !  No place to build or expand current highways, but,  if the IDIOTS were taken off the roads,  then there would not be a Problem !!!

Not to mention the milllions of Mexicans with no insurance, no license, bald tires, no brakes, expired tags tailgating you. Then after the accident its called a hit and run, litterly running into the bushes. What a cess pool LA is.
