The United States Congress supports
the effort to examine the deficiencies in NASS and to plan for a
modernized and comprehensive data system. United States Senate
Report #112-83 and House Report #111-564 direct NHTSA to evaluate
the NASS CDS data collection program. The reports advise NHTSA to
provide to the House and Senate Committee on Appropriations a
review of the NASS modernization efforts. NHTSA is undertaking a
modernization effort to upgrade its data systems by updating the
data collected and reexamining the NASS sample sites and sample
size. The new sample design has three stages. The first stage
selects geographic locations around the country, the second stage
selects law enforcement agencies within the geographic areas, and
the third stage samples Police Accident Reports (PARs). Using
updated population and other auxiliary information, NHTSA has
identified a new set of probabilistically selected geographic
locations around the country that are expected to provide a more
accurate traffic safety picture, more precise estimates, and
greater insight into new and emerging data needs. This collection
of information will assist NHTSA with the next step in updating the
NASS sample design, which is to select a fresh sample of law
enforcement agencies within these Primary Sampling Units (PSUs).
This requires compiling basic crash count data from every law
enforcement agency that responds to motor vehicle crashes in the
PSUs. This data would be used to construct a measure of size in
order to make informed and efficient choices in the probabilistic
selection of the second stage sample units, the law enforcement
agencies. It is this need to make informed and efficient choices in
the NASS redesign that makes the proposed collection
necessary.
On behalf of this Federal agency, I certify that
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).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
