Sources of statewide AADT data/shapefiles

[froggie]

Related to the US traffic volume map thread.  I'm looking at updating the maps I created for that thread with more recent traffic volume data, as well as adding select non-Interstate highways.  The national set I used for those maps, as I found out, is 2002 traffic data.  I'd like to find more recent data and here's where I was hoping you all could help me out, so I can focus my limited bandwidth (and time) on getting the data during my next couple port visits.

Shapefiles would be an extra plus (eliminates having to hand-code the data into GIS), but I'll take whatever format I can find the data in.

My target year is 2010, though I'll take data anywhere in the 2009-2013 range.

I only have current GIS files for Florida, Minnesota, and Vermont, though I have current non-GIS data for Maryland, Tennessee, and Virginia.  Looking for data period for all of the remaining states plus Puerto Rico.

Thanks in advance!

You should find easily data for Pennsylvania on the PASDA website : http://www.pasda.psu.edu/

Thanks guys, I was indeed able to grab those, as well as Maryland, Virginia, New York, and North Carolina.  The PA and OK ones don't specify which year the counts took place, and I didn't see that info in the metadata either.
