Thanks for the clarification Meghna. This went out before I joined the listserve, so that lack of knowledge skewed my recommendation.

Subject: [CTPP] TAZs and TADs for CTPP 2006-2010 are available now!
Although CTPP 2006-2010 will not be out until the year of 2013, but Traffic Analysis Zone (TAZ) and Traffic Analysis District (TAD) delineated for CTPP 2006-2010 are available now in the Census Bureau FTP site. Here is the link:
For TAZ, go to this ftp site
ftp://ftp2.census.gov/geo/pvs/tiger2010st/
[THEN PICK YOUR STATE Folder--you have to select the state-level directory twice. TAZ files are NOT under the county-level directory, only the state. The file name is tl_2011_XX_taz10.zip (where XX= State FIPS) For example, South Caroline TAZ files are in this directory:
<ftp://ftp2.census.gov/geo/pvs/tiger2010st/45_South_Carolina/45/tl_2011_45_taz10.zip><ftp://ftp2.census.gov/geo/pvs/tiger2010st/45_South_Carolina/45/tl_2011_45_taz10.zip>
TAD:
ftp://ftp2.census.gov/geo/pvs/tiger2010st/
[SCROLL to BOTTOM]
File name is: tl_2011_us_tad10.zip
<ftp://ftp2.census.gov/geo/pvs/tiger2010st/tl_2011_us_tad10.zip><ftp://ftp2.census.gov/geo/pvs/tiger2010st/tl_2011_us_tad10.zip>

Natasha/Kevin,
Responding to Kevin’s point, I just looked (for my own curiosity), and didn’t find the TAZs. I would check with Shonin Anacker (copied on this message) at U.S. Census Bureau on this. Here’s his contact information:
Shonin Anacker
Supervisory Geographer
Geographic Areas Branch
Geography Division
US Census Bureau
301-763-9052
Shonin was the point of contact for me when my organization was working on developing our region’s CTPP TAZs back in 2011, and he was a really good resource. Just to re-state the obvious, the 2011 program was a voluntary submission to Census, allowing local jurisdictions (i.e., MPOs) to suggest what zone structure to use for compiling the CTPP using the ACS.
As I understand it, if a region decided not to participate, then Census Bureau went with what best fit their needs, starting with the pre-existing zone structure they had on file. So, there may not be “updates” for all regions.
I wonder if Natasha’s request isn’t jumping the gun a bit. According to the CTPP website (http://www.fhwa.dot.gov/planning/census_issues/ctpp/), the CTPP based on the 2006-2010 ACS dataset isn’t scheduled to be released until May 2013.

Have you looked for it as a downloadable .shp layer from Census TIGER website?
