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_t…
<
ftp://ftp2.census.gov/geo/pvs/tiger2010st/45_South_Carolina/45/tl_2011_45_t…
TAD:
ftp://ftp2.census.gov/geo/pvs/tiger2010st/
[SCROLL to BOTTOM]
File name is: tl_2011_us_tad10.zip
