Note
from Elaine:
As
you know, FHWA and AASHTO received the 2006-2008 CTPP files from the Census
Bureau at the end of July. FHWA made one key table available and posted
it on the Cambridge Systematics web page, originally on July 30, with a
corrected version on August 2 (duplicate records were removed). ftp://ftp.camsys.com/temp/outgoing/CTPP/New%20CTPP%20ACS/
We
are now working on making a Place-to-Place file (limited to the 2006-2008 CTPP)
and should have it checked and available by early next week. As I might
have mentioned before, this is a good example of “swiss cheese” since
Places that fall below the 20,000 residence population threshold are missing,
and unincorporated areas of counties are also missing (since they are not a “place.”)
Note
from Caliper:
For
your convenience, Caliper Corporation has processed these data into two
matrices, and one for the CTPP ACS 2006-2008 data (30MB) and one for the CTPP
2000 data (24MB). We have also provided the data in the form of ESRI personal
and file geodatabases for ArcGIS users in your organization. All of these files
can be downloaded from the Caliper User Center. If you are not a TransCAD User,
you may register as a guest to obtain the data at http://usercenter.caliper.com. We
expect to make the full set of CTPP 2006-2008 tabulations available after they
are released in September of this year.
