Traffic congestion dropped off 30% in 2011 INRIX says - weak economy, higher gas prices
2012-05-21 21:30: 2011 saw a dramatic drop in traffic congestion in the US - 30% fewer hours wasted in congested traffic according to INRIX, the nation's leading provider of traffic data. The 2011 improvement is only outmatched in the years since INRIX has been measuring congestion by the financial crisis year of 2008, when congestion dropped 34%. In 2009 congestion was up 1% and 2010 saw a 10% regrowth of congestion.
But now we learn 2011 saw congestion drop again, and well below 2008 levels.
In a press statement the Seattle area based company says the decline in congestion is attributable to the "'Stop-’N’-Go Economy' where lack of employment combined with high fuel prices is keeping Americans off the roads."
Bryan Mistele INRIX chief executive: "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."
Congestion is most acute in large metro areas, and INRIX notes that last year, only 890,000 of the 2.6 million new jobs were in large urban centers. The biggest reduction in congestion has been in the cities' with the largest job losses.
Says INRIX statement: "Lack of employment combined with high fuel prices is clearly driving the decline in traffic."

INRIX says its reporting is based on analysis of billions of raw data points from INRIX’s historical traffic database of about 100 million vehicles traveling the roads everyday including taxis, airport shuttles, service delivery vans, long haul trucks and passenger cars. Each data report from these GPS-equipped vehicles and devices includes the speed, location and heading of a particular vehicle at a reported date and time.

methodology for the INRIX report:
COMMENT: President Obama has a concrete accomplishment here on which to run for re-election. Campaign slogan: "I got 30% of the bums off your road." Promise: "Re-elect me for another term and I'll finish the job."
EXTRA May 22: INRIX explain that the 30% reduction in congestion is based on US INRIX Index (II), a key indicator of traffic congestion, was 5.9 in 2011, down 30% from 2010 (8.4) based on the delays in the average trip in the nation’s "Top 100 Most Populated Cities." In 2010 the trip took 8.4% longer than if there was no traffic congestion whereas in 2011 it took 5.9% longer than if there was no traffic congestion.
They also report that in 2011, only 30 metropolitan areas saw increased congestion vs. 2010. With the remaining 70 metros experiencing declines or no change in traffic, the picture of traffic congestion is the exact opposite of 2010 where 70 regions saw increases in congestion compared to the prior year.
They say: "All congestion is not created equal: The nation’s worst travel corridors can cost their drivers more than 60 hours of annual delay in the evening peak period alone. Over 1,400 miles of our nation’s main corridors were congested last year, down from 2,300 miles in 2010. When examined with employment and fuel price data from 2011, the Scorecard shows how observed shifts in traffic congestion serve as a key indicator of economic health."
