Abstract: The National Highway Traffic Safety Administration (NHTSA) is seeking approval for this new information collection request (ICR) 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, will add to the body of knowledge, and will inform future agency activities; however, it is not associated with immediate regulatory activities. 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 individual data collections, approved by the Institutional Review Board at the University of Michigan, will each be performed once. Study participants will be male and female licensed adult drivers from the general public, and participation will be voluntary with compensation. For an in-lab study, information collections include (1) an online screening questionnaire; (2) an eligibility phone call to confirm eligibility, interest, and to schedule a time in the lab; and (3) informed consent for the in-lab study and anthropometric measurement. A subset of the in-lab participants will be asked to participate in an in-vehicle study to include (1) a pre-drive questionnaire for the in-vehicle study; (2) informed consent for the in-vehicle study and anthropometric measurements; and (3) a post-drive questionnaire for the in-vehicle study. 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 crash safety and occupant protection through the development of human body models (HBMs) and anthropomorphic test devices (ATDs). A technical report on the project and outcomes will be prepared and published. The annual burden hours for the new collection are estimated to be 341 with an estimated $11,379 in opportunity costs.
