Me too! George Petrek Engineering Spec III TPP, Traffic Analysis Section P.O. Box 149217 Austin, TX 78714-9217 phone: (512) 486-5140 fax: (512) 486-5153 e-mail: gpetrek(a)dot.state.tx.us 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.
