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.
