Hi Diana – I thought I had responded to your query, but I was looking at the listserv archive and saw that it was not answered on the CTPP listserv.

The current expectations are that the CB would deliver to AASHTO a CTPP 5-year file (with TAZ and TAD as tabulation geography) by December  31, 2012.  But, then, AASHTO would need to work with someone for web-based data access.  For the CTPP 2006-2008, Beyond 2020 is the main contractor.  From the time the CB delivered the CTPP 3-year file, it took over 4 months to get the data on the AASHTO website, but there was a steep learning curve, and the CB did not supply any TEST data for the software developer to use, only empty table shells.     Being an optimist, it would presumably take less than 4 months in the next iteration, however, the very large number of TAZs and census tracts are likely to give any software vendor a headache, especially with the flow tabulations (Part 3).
