COLLEGE STATION, TX. — According to the Texas A&M Transportation Institute’s Urban Mobility Report, traffic congestion in large U.S. cities is cost the trucking industry $27 billion in wasted time and fuel in 2011, not including the value for any goods being transported.

In total, traffic congestion cost the economy $121 billion, the report said, adding that congestion solutions aren’t being pursued aggressively enough.

“The most effective congestion reduction strategy,” the reports authors wrote, “is one where agency actions are complemented by efforts of businesses, manufacturers, commuters and travelers. There is no rigid prescription for the “best way”— each region must identify the projects, programs and policies that achieve goals, solve problems and capitalize on opportunities.”

Washington, D.C. topped the list of regions with the worst congestion, followed by Los Angeles, San Francisco-Oakland, New York-Newark, Boston, Houston, Atlanta, Chicago, Philadelphia and Seattle.

The report said that the national U.S. congestion invoice for 2020 will grow to $199 billion (2011 dollars), delay will grow to 8.4 billion hours, and 4.5 billion gallons of fuel will be wasted.
