Ranking the most congested cities and the worst traffic bottlenecks


The INRIX National Traffic Scorecard 2009 Annual Report provides a comprehensive analysis of the state of congestion in 2009 across America and how it changed versus 2008. The report found that traffic gridlock, during peak periods on major roads in urban America, had reached its low point in the second quarter of 2009 and is starting to rise again. However, in the aftermath of the recession, traffic congestion nationwide has experienced a reset to 2005 levels – providing a welcome respite from the levels of gridlock we experienced in 2006 and 2007. While signs indicate congestion is back on the move again, the rate at which gridlock gets worse on our nation’s roads will depend on the pace of economic recovery – particularly job growth and fuel prices.
