SUPPLEMENTARY INFORMATION: Under the Paperwork Reduction Act of 1995
(44 U.S.C. 3501 et seq.), before an agency submits a proposed
collection of information to OMB for approval, it must first publish a
document in the Federal Register providing a 60-day comment period and
otherwise consult with members of the public and affected agencies
concerning each proposed collection of information. The OMB has
promulgated regulations describing what must be included in such a
document. Under OMB's regulation (at 5 CFR 1320.8(d)), an agency must
ask for public comment on the following: (a) whether the proposed
collection of information is necessary for the proper performance of
the functions of the agency, including whether the information will
have practical utility; (b) the accuracy of the agency's estimate of
the burden of the proposed collection of information, including the
validity of the methodology and assumptions used; (c) how to enhance
the quality, utility, and clarity of the information to be collected;
and (d) how to minimize the burden of the collection of information on
those who are to respond, including the use of appropriate automated,
electronic, mechanical, or other technological collection techniques or
other forms of information technology, e.g., permitting electronic
submission of responses. In compliance with these requirements, NHTSA
asks for public comments on the following proposed collection of
information for which the agency is seeking approval from OMB.
Title: Occupant Anthropometry and Seating.
OMB Control Number: New.
Form Number(s): NHTSA Form 1824, NHTSA Form 1825, NHTSA Form 1826,
NHTSA Form 1827, NHTSA Form 1828, and NHTSA Form 1848.
Type of Request: New information collection.
Type of Review Requested: Regular.
Requested Expiration Date of Approval: 3 years from date of
approval.
Summary of the Collection of Information:
NHTSA proposes to collect information from the public as part of a
study to collect detailed information on current body size and shape,
posture, and motion of vehicle occupants. This research will support
NHTSA in the development of tools used for occupant protection during
crashes, particularly in the context of equity in crashworthiness. This
research will add to the body of knowledge and is not immediately
intended to inform regulations or policy.
The designs of anthropomorphic test devices (ATDs, commonly known
as crash test dummies) are based on measurements of volunteers sitting
in vehicle and laboratory seats. The current generation of ATDs is
based on data gathered at University of Michigan Transportation
Research Institute (UMTRI) in the 1980s. Since that time, the U.S.
population has change substantially, most notably due to the large
increase in body mass. Measurement technologies have also improved
dramatically with the development of fast three-dimensional surface
measurement systems. Seating configurations have also expanded from the
traditional seat posture collected in the 1980s with increased recline
angles in modern vehicles. This combination of a population size shift
and more variable seat configurations presents a clear need for updated
seated anthropometry to be collected with new advanced anthropometry
measurement capabilities.
The data collections, approved by the Institutional Review Board at
the University of Michigan, will be performed once to obtain the target
number of valid test participants. Study participants will be male and
female licensed adult drivers from the general public, and
participation will be voluntary with monetary compensation provided.
Participants are recruited using University of Michigan's Health
Research portal, <a href="https://umhealthresearch.org/">https://umhealthresearch.org/</a>. The voluntary study
would involve recruiting licensed drivers for two studies (in-lab and
in-vehicle). For the in-lab study, the following information
collections include: (1) an online screening questionnaire; (2) an
eligibility phone call to confirm eligibility, interest, and schedule a
time in the lab; (3) informed consent for the in-lab study and
anthropometric measurement. A subset of the in-lab participants will be
asked to participate in the in-vehicle study and the following
information collections include: (1) a pre-drive questionnaire for the
in-vehicle study; (5) informed consent and anthropometric measurements
for the in-vehicle study; and (6) a post-drive questionnaire for the
in-vehicle study.
In this study, 3D surface scan data quantifying body size and shape
in a range of postures will be obtained. Posture, position, and belt
fit in driver and passenger seating mockups that are adjusted to a wide
range of vehicle configurations and using multiple seats will be
measured. The participants will be selected to span a wide range of
stature and weight, spanning the 5th percentile female to 95th
percentile male values. Individuals with high body mass will be
preferentially selected to address the current lack of data from that
cohort. An in-vehicle study will be conducted using participants
recruited from among those participating in the laboratory study.
Participants will be provided an instrumented vehicle to drive in place
of their own for a 7-to-10-day period. Given unknown budget
appropriations the drive time may be reduced from 7-to-10-days to two
hours. Independent of budget appropriations the burden to the public is
two hours. The two hours will either be spent as more detailed check
in/check out time for the 7-to-10-day plus questionnaire post-drive or
as a 2-hr drive starting and ending at the lab. The goal of the in-
vehicle study is to validate the driver postures measured in the
laboratory and to obtain high-resolution 3D data on postures and
movements during driving. A particular focus is on the lower
extremities, where crash injury data have indicated a large difference
in risk between male and female drivers. Body scans, measurements, and
any video will be de-identified prior to submission to NHTSA.
Statistical models will also be developed from de-identified data and
made available to the public through a software tool.
This research study will gather a new database of information on
adult body size, shape, posture, and motion to support advancement in
these safety applications. This study will add to the body of the
knowledge on motor vehicle anthropometry and will support female crash
safety and equitable occupant protection through the development of
human body models (HBMs) and anthropomorphic test devices (ATDs).
Description of the Need for the Information and Proposed Use of the
Information:
Early ATDs, including the Hybrid-III family that was initially
designed in the 1970s, were constructed using manually gathered
anthropometric data, such as segment lengths and circumferences.
Minimal 3D information was available, and seated postures were
approximated. In 1980, NHTSA funded a large-scale study at UMTRI to
develop anthropometric specifications for a new generation of ATDs. The
Anthropometry
[[Page 106743]]
of Motor Vehicle Occupants (AMVO) study gathered data and developed
detailed 3D body shapes for small female, midsize male, and large male
occupants, using 5th percentile female, 50th percentile male, and 95th
percentile male stature and body weight as the target reference values.
Drawing packages were developed detailing landmark and joint locations,
and physical 3D surface shells were constructed using landmark data and
minimal 3D contour information. These data have formed the
anthropometric basis for most adult ATDs developed since that time,
including the THOR family.
AMVO had some limitations, however. Due to the limits of the
technology available at the time, a small number of participants were
measured (25 per size bin were used to create the final
specifications), and no 3D surface information was collected. Moreover,
the analysis was based on simple averaging per size bins, so no
information was provided for other occupant sizes. Most importantly,
the midsize female was dropped for cost reasons, so the only female
data were gathered from very small individuals.
Over the past 20 years, HBMs have become an important addition to
the biomechanics toolkit. Using the same logic that was applied to
selecting body sizes for ATDs, the HBMs have typically been targeted to
the same stature and body weight reference values as were used in AMVO.
However, unlike the averaging process used in AMVO, most HBMs have
developed using data primarily or entirely from a single individual. A
consequence of this approach is that HBM development has not provided
meaningful additions to the anthropometric data available to
characterize vehicle occupants.
In the decades since AMVO, UMTRI has conducted a large number of
studies of occupant posture and body shape and has developed
advancements in both measurement and analysis methodology. Of
particular importance, rather than averaging data to create a
representation of a single body size, UMTRI has developed continuous
statistical models that can generate accurate specifications for a wide
range of sizes and shapes (for examples, see <a href="http://HumanShape.org">http://HumanShape.org</a>).
Simultaneously analyzing both landmark locations and 3D body shapes has
enabled the development of parametric human body modeling, in which
HBMs are morphed to represent people with widely varying size and
shape.
Concurrent with the development of parametric HBMs, crash injury
data analyses have highlighted the potential benefits of these new
tools. In particular, the field data indicate that female occupants
experience higher risks of some injuries in certain types of crashes.
Notably, lower-extremity injury risks are markedly higher for female
drivers than for male drivers in frontal impacts. Detailed
anthropometric and posture data for female drivers could help to
elucidate the causes of this difference. Crash injury data also show
that individuals with high body mass are at higher risks of some
injuries, possibly due to differences in the interaction with the
restraint systems. Minimal data are available to describe the seated
postures and body shapes of this cohort, which is increasingly
important in the U.S.
Affected Public:
Respondents will be licensed drivers, ages 18+, in the Ann Arbor,
MI region and willing to travel to UMTRI. Study participants will be
male and female licensed adult drivers from the general public, and
participation will be voluntary with monetary compensation provided.
Participants are recruited using University of Michigan's Health
Research portal, <a href="https://umhealthresearch.org/">https://umhealthresearch.org/</a>. Prospective
participants will respond to the U-M Health Research posting by
completing a screening questionnaire on a Google Form. Eligible
participants are those whose answers to the Google Form questions are
consistent with the inclusion and exclusion criteria.
Eligibility requirements include the ability to read and speak
English, ability to drive for two hours continuously, hold a current
and unrestricted U.S. driver's license, have been a licensed driver for
at least one year, drive a car daily for an average of at least 15
minutes, and comfortable driving on the highway and local roads.
Exclusion criteria include individuals with musculoskeletal ailments
impeding the ability to walk or sit comfortably or musculoskeletal
deformities such as scoliosis or amputations.
Estimated Number of Respondents: 2000.
We estimate that 2000 screening questionnaires will be filled out
to obtain the needed number of subjects. The form has 23 questions,
including name, address, and time slots available. We estimate that up
to 600 individuals will need to be contacted to obtain the needed
number of 300 subjects for the lab study. This considers that some
people's schedules may not match up with lab openings or they may not
show up for their scheduled appointment. A subset of the in-lab study
participants will be asked to participate in the in-vehicle study with
the targeted 100 participants.
Frequency: Once.
This is a one-time collection of information with two studies: in-
lab and in-vehicle. A subset of the in-lab participants will be asked
to participate in the in-vehicle study. The initial pre-screening time
is roughly 5 minutes and can be done at the respondents' convenience
using a device of their choosing. The only requirement is an internet
connection to access the online pre-screening. Not all who begin this
pre-screening will complete the form in its entirety, and not everyone
will meet study criteria. Those who meet study criteria could be
contacted for an eligibility phone call prior to study enrollment.
Estimated Total Annual Burden Hours:
The annual estimated time burden to complete the collection of
information is 347 hours and an annual opportunity cost of $16,373.05
over the study period. To minimize the burden of the screening
questionnaire and eligibility phone call, individuals for the in-
vehicle study will be selected from the in-lab study pool. An estimate
of up to 2000 individuals will initiate a response to the online
screening questionnaire due to the broad range of inclusion criteria.
Of the screened individuals we anticipate that up to 600 will need to
be contacted for an eligibility phone call to obtain the needed number
of 300 participants scheduled for the in-lab study. Scheduled
participants that do not show up will be replaced from the remaining
pool of screened participants and eligibility phone call to ensure 300
individuals arrive for in-lab measurements. After completion of the 2-
hour process for informed consented and in-lab data collection, some
participants will be asked if they are interested in the in-vehicle
study. From the 300 in-lab participants, 100 will be scheduled to
return to the lab for the in-vehicle study. The in-vehicle pre-drive
and post-drive questionnaires will each take 5 mins, the informed
consent, vehicle check-out, and vehicle check-in processes will take
110 min. totaling 2 hrs. for all of the in-vehicle study.
To calculate the opportunity cost associated with the forms and
other relevant activities necessary for this collection of new
information, NHTSA looked at average hourly earnings for employees
across all occupations in the Ann Arbor, MI area. The Bureau of Labor
Statistics (BLS) estimates that the average hourly wage for this group
is $33.43, thus serving as the opportunity cost per hour. The Bureau of
Labor Statistics estimates that private industry
[[Page 106744]]
workers' wages represent 70.3% of total labor compensation costs.
Therefore, NHTSA estimates the hourly labor costs to be $47.55. NHTSA
estimates the total opportunity cost associated with the 1033 burden
hours to be $49,119.15. Annual burden cost is estimated to be
$16,373.05, and annual burden hours is estimated to be 347. There may
be a slight variation in the comparison of total to annual burden over
the three years due to rounding. The annual burden figures will be
those represented in ROCIS.
