While you are still waiting for the CTPP full data release with the
access software (scheduled on December, 2010), don't forget FHWA
prepared and released the county-to-county and place-to-place flow
tables prior to full data's formal release. The flow tables are for
Total Workers and for 18 categories of Workers by Means of
Transportation. County level data also included CTPP 2000 data but
categorized only by 8 transportation modes. We have NOT included the
CTPP2000 for Place-to-Place data files because of difficulties in
matching FIPS codes for Places between 2000 and the current CTPP. These
two files are published in CS FTP sites:
ftp://ftp.camsys.com/temp/outgoing/CTPP/New%20CTPP%20ACS/
Also, transportation profiles using ACS 2005-2007 and CTPP2000, which
give people a quick transportation snapshot of their areas are also
published at AASHTO CTPP website.
