Mike,
I think you were looking at the detailed Part 3 (worker flows) for the 1990 CTPP in the
Transtats website. For CTPP 2000, the part 3 tables do contain a table for workers by
mode. Please visit
http://www.fhwa.dot.gov/ctpp/tables.htm for the specifications for CTPP 2000.
Currently, Census Bureau (CB) is working hard to release part 1 (Residence end tables) for
CTPP 2000. We are hoping that CB will release the part 3 tables in the latter part of
2003.
Thank you
Nanda Srinivasan

The 1990 Journey to Work files from
http://www.transtats.bts.gov/ has
worker trips specified by mode of transport, including how many people
are in a carpool, which enables me to figure out the actual car
traffic.
The 2000 data from
http://www.census.gov/population/www/cen2000/commuting.html
only seems to have total numbers of workers, not their modes of
transport.
Does anyone know where I can get the more detailed information that I
was able to get from the 1990 data?
Thank you.
