The trend beating every year since 2008 began in April, so that makes 6 straight months of improving mobility levels on American roadways. Prior to April the up-trend was preceded by a number of months only beating 2012 and 2013 levels.
The level was 2.982 trillion miles in September 2014. In 2008 it was 2.989 trillion.
The peak year was 2007 at 3.035 trillion miles. The trough year was 2011 at 2.948 trillion miles.
We are slowly but convincingly climbing out of the depression in American travel in 2014.
