The average over the full US is kind of meaningless as most areas don't have traffic problems. It's only large city's that actually matter in this assessment.

On page 4, 2006: 80% used a carpool or single occupancy car. 2013: 76% used a carpool or single occupancy car which is counter to their narrative. Further, metro areas are rather large, I commute less than 3 miles on secondary roads in the DC metro area from just outside the beltway to just inside of it and encounter approximately zero traffic.
