Mark Perry at Carpe Diem notes the continued rise in traffic volume.  He writes:

The sustained and ongoing improvements in vehicle miles since the summer of 2009, along with a record-high volume for the month of September, indicate that the U.S. economy is recovering gradually, and the chances of a double-dip recession are negligible.

The chart below shows the traffic trend.  (See also Calculated Risk for a less optimistic take on this trend.)
