RE: [CTPP] Census Journey to Work Question

Here is a link to the Census "long form" which includes the "journey to work" questions. http://www.census.gov/dmd/www/pdf/d02p.pdf Yes, it only the trip TO work. And, yes, you can double it to approximate a "round trip." Results from the National Household Travel Survey (NHTS) http://nhts.ornl.gov/2001/index.shtml show that many more people STOP on their way home from work, we call this "trip chaining." Results from the 1995 NPTS show that 60% of women, and nearly 50% of men make a stop on their way from work to home. So, the result is the that trip from work to home, including one or 2 stops is often considerably longer than the trip TO work. http://www-cta.ornl.gov/npts/1995/Doc/Chain2.pdf Thank you for sharing the Arbitron application. You may also be interested in the county-level CTPP profiles that were released last October. http://www.fhwa.dot.gov/ctpp/dataprod.htm These have a few tables, including comparisons to 1990 results, and tables of commute time by mode of travel, and vehicle availability by household size. This same link also has information on the Census Bureau's County-to-County worker flow data. The CTPP Part 1 (residence) tables will begin release in a few weeks. They will be mailed initially to the State DOTs and MPOs for their review, before they are released broadly and publicly. Elaine Murakami Federal Highway Administration 206-220-4460
