The NHTS is the U.S. Department of
Transportations only inventory of passenger travel. The data are
used to determine current travel characteristics, such as the
relative proportion of travel by mode (e.g. vehicle, transit, and
walk) and purpose (e.g. work, school, family/personal, and
recreational) by residents of U.S. households. These data allow the
Department to evaluate the adequacy of existing transportation
facilities and estimate future needs. The NHTS is consolidated with
other data to provide a bi-annual report to Congress.
The burden was reduced from the
2001 survey by editing the questionnaire to only the most critical
data elements and eliminating the reporting of odometer readings
twice over a two-month period. An adjustment for burden was also
made due to two methods changes. In 2001, the NHTS collected trip
information for children under the age of five. Based on an
analysis of the number of trips taken by children under five
without a household member, we have determined that we no longer
need to collect data on children under the age of five. In
addition, a separate module for the collection of long distance
trip information has been removed from the 2008 NHTS.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
