No job? Gas nearing $3 a gallon? No worries. There’s an upside. Drivers are spending less time struck in rush-hour traffic, the first-ever two-year decline in congestion, a national report in today’s Denver Post indicates. LA traffic is improving, but is still the worst nationwide. No surprise there. Some of the details from the report released today by the Texas Transportation Institute: The average U.S. driver languished in rush-hour traffic for 36.1 hours in 2007, down from 36.6 hours in 2006 and a peak of 37.4 hours in 2005. Total wasted fuel also edged lower for the first time, from 2.85 billion gallons in 2006 to 2.81 billion, or roughly three weeks’ worth of gas per traveler.
