Traffic: Congestion Plummets WorldWide

Traffic congestion worldwide dropped a “startling” 30% in 2011.  Seventy of the hundred largest US cities had traffic decreases last year.  Unemployment and gas prices are cited as principal factors.

“The declines in traffic congestion across the U.S. and Europe are indicative of stalled economies worldwide,” said Bryan Mistele, CEO of INRIX, which provided the findings.  “In America, the economic recovery on Wall Street has not arrived on Main Street. Americans are driving less and spending less fueled by gas prices and a largely jobless recovery.”

  • The cities with the biggest drops in congestion also have gas prices that exceed the national average.  These include Los Angeles, San Francisco, and Honolulu.
  • Cities with employment growth over the national average (Tampa, Houston, and Austin) had some of the biggest increases in congestion.

The report is the first of its kind to rank and provide detailed information on the 100 most congested U.S. metropolitan areas and the 100 worst traffic corridors nationwide. In creating the Scorecard, INRIX analyzes information for more than 300,000 miles of roads in the U.S. and 250,000 km in Europe during every hour of the day to generate the most comprehensive and timely congestion analyses available.  INRIX is based in Kirkland, WA.
