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.

New subject: How can I get more detailed CTPP 2000 files?
you can get county level residents (on modes used to got to work) data
from the profiles at
http://www.transportation.org/ctpp/
for any modal information on the flows you will have to wait until the
summer when the flow data portion of the ctpp is released.

This was useful but while we are asking, the 1990 JTW data included not only
mode fractions but also average trip time and trip distance by mode for the
larger cities and MSA's. Will these be available? When and were?
Thanks
