Performance Specifications for a Midsize Male Pedestrian Research Dummy
- Ground Vehicle Standard
While it is recognized that collisions involve pedestrians of all sizes, this Information Report addresses performance specifications for a midsize adult male research dummy. This approach stems from the greater knowledge of biomechanics and existing dummy technologies for the midsize male relative to other adult sizes and children. While not the initial objective, it is envisioned that additional performance specifications for other sizes of pedestrian research dummies will be developed in the future based on accepted scaling procedures.
The specific requirements for the pedestrian dummy have been based on a collective assessment of pedestrian injury, response, and anthropometry priorities from the experimental, epidemiologic, and computational literature. In general, the objective was to specify performance specifications based on human characteristics and the impact response of post mortem human subjects rather than to specify the design of a particular physical device.
Based on the perceived applications for a research pedestrian dummy, the primary focus of this document centered on biofidelic whole-body kinematics during a vehicle-pedestrian impact. Specific body regions were prioritized (see A.1.5) based on a combination of pedestrian injury, including both severity and frequency. Based on the priorities established by a review committee, the specifications provided in this document include both mandatory and recommended requirements as indicated by the terms “shall” and “should,” respectively. As pedestrian injury trends and dummy hardware continue to evolve in the future, it is anticipated that this document will expand to include more mandatory requirements in more body regions.
Finally, it should be noted that the test procedures described in this document only apply to the specific tests required to assess pedestrian dummy biofidelity. It is anticipated that pedestrian dummies meeting the performance criteria of this document will be used in a wide variety of tests, requiring specialized test and data procedures.

The Human Biomechanics and Simulation Standards Committee is part of the Occupant Protection and Biomechanics Steering Committee that reports to the Motor Vehicle Council (MVC). The Standards Committee is responsible for developing and maintaining SAE Standards, Recommended Practices, and Information Reports related to assessing vehicle occupant and pedestrian protection. The Committee's goal is to provide an unbiased assessment of these documents as well as provide input to associate International Organization of Standardization (ISO) activities. Committee experts with broad backgrounds in the field represent a variety of viewpoints. The following committees and task forces have been developed under the committee's scope: Hybrid III Dummy Family Task Force, Pedestrian Dummy Task Force, DAPRR Task Force, Dummy Testing and Equipment Committee. Participants in the SAE Human Biomechanics and Simulation Standards Committee include OEMs, suppliers, consulting firms, government, and other interested parties. The HBSS shall pursue anthropometrically, biomechanically sound definitions of mechanical and analytical surrogates of humans for use in research, design, development, and certification studies involving occupant/vehicle and vehicle/pedestrian impact injury. Likewise, it shall pursue pertinent, biomechanically sound definitions of impact injury criteria to enable, in conjunction with the use of surrogates, predictions of the degrees of human injuries to be expected in a given impact environment. (This objective was developed at the 1st HBSS meeting January 14, 1976)
