Approved through
February 2004 with report to OMB by March 2002 on results of
efforts to determine what feasible alternatives are available to
remedy the problem of nongeneralizability related to nonresponse in
the use of telephone survey methodology together with a definitive,
detailed plan to implement such remedies, and a second report to
OMB by March 2003 detailing progress in implementing the plan. OMB
recognizes the effects of BTS and FHWA to find ways to improve the
generalizability of survey results from this important national
survey. We remain concerned that levels of response below the
levels expected of such surveys will mitigate against valid,
generalizable results. In our discussions with BTS and FHWA, we
believe this problem is clearly understood and appreciate efforts
to remedy the problem that were set forth in the October 5, 2000,
submission reporting on pretest results and attempts to deal with
problems of nonresponse. Subsequently, DOT (BTS) has described
additional efforts such as (a) nonresponse analysis using address
match data, and (b) the analysis of the nonrespondent
population--for example, the characteristics of potential
respondents lost between recruitment and survey completion. BTS,
working with the National Reseach Council, will also be undertaking
a 3 year effort to look at alternatives to current methodologies in
this area. The reports to OMB will provide the needed analysis to
determine what methodology should be utilized, as well as address
other acknowledge problems. OMB will rely heavily on the reports
required by these terms of clearance when considering approval of
the initiation of another major personal travel survey of this
kind.

The NPTS obtains information from a
national sample of households on the amount and nature of personal
travel in the U.S. Results are used by the U.S. DOT to address
national transportation policy issues, forecase future travel
demand, analyze use of various modes of transportation and
calculate highway accident exposure rates.

the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
