[CTPP] CTPP 5-year (2006-2010 ACS) schedule
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).
