(CBS Seattle) – Does your commute through the Emerald City make your fists tighten and teeth grind? Odds are it does.
Seattle has the fourth worst traffic congestion problem in North America, according to a new survey by Tom Tom.
The report shows Seattle as providing a roughly 30-minute delay per hour for drivers. Friday afternoon’s rush hour ranks as the worst time to travel through Seattle, whereas Monday evenings rank as the least painful.
The average speed during the worst-clogged commute is 34 miles per hour.
In 2011, Seattle was ranked 12th; the city’s eight-point jump is the second most of any major North American city. Houston saw the worst spike, moving from number 18 to number eight.
Los Angeles finished at number one for the second year in a row, boasting a 77 percent congestion rate during evening peak hours. Vancouver, B.C. ranked second and Miami jumped to the third spot.
Edmonton, Alberta had the biggest drop-off in congestion, falling from number 8 to number 23.
Researchers looked at travel times during non-congested periods with travel times in peak hours. The difference is the percentage increase in travel time. All the data is based on actual GPS based measurements; for each city, the sample size is expressed in total number of measured miles for the period.
A comparison is made for the travel times during the quarter and then compared with the same period a year ago.
