The researchers at the Texas Transportation Institute have recently published new estimates of the effects of traffic congestion. The trend toward increased congestion eased in 2007 and 2008 with the downturn in the economy but began to rise again in 2009 along with economic activity. In 2009, nearly 4 billion gallons of fuel were wasted due to traffic congestion; up 160 million gallons from 2008 but still lower than the peak of 4.4 billion gallons wasted in 2006.
