[CTPP] Information from Caliper Corp

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/ <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 <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.
