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)
show that many more people STOP on their way home

Thank you for sharing the Arbitron application. You may also be interested in the
county-level CTPP profiles that were released last October.
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
