Dynamic Response Corridors and Injury Thresholds of the Pedestrian Lower Extremities

Current standards and test devices for pedestrian safety were developed using results from impact tests where inertial considerations have dominated and the vehicle pedestrian loading environment has not been properly replicated. When controlled tests have been conducted to evaluate injury criteria and the biofidelity of anthropometric test devices, current designs have faired poorly. The present study uses recently published results from controlled tests to develop force-deformation and moment-deformation response corridors with localized injury thresholds for the 50th percentile adult male thigh, leg, and knee subjected to latero-medial bending at rates characteristic of the vehicle pedestrian loading environment. The response corridors provide necessary information for development of biofidelic ATDs [anthropometric test devices] for evaluation of countermeasures for pedestrian lower extremity protection.
