Efforts to develop a dummy capable of assessing injury risk in a pedestrian collision require biofidelity assessment targets in full‐scale pedestrian‐impact scenarios. The goal of this study was to develop trajectory analysis methods and kinematic biofidelity corridors for 50th percentile male adults subjected to 40 km/h pedestrian impacts using a recently‐developed generic sedan buck. Tests were performed with three male post‐mortem human surrogates initially positioned to be struck laterally in a mid‐gait stance. The kinematics of the post‐mortem human surrogates were recorded via high‐speed video imagers and a 3D optoelectronic motion capture system. Trajectories of the head center of gravity, T1, T8, and the pelvis were digitized via a 2D video (up to the time of head impact). The 2D trajectory data were verified against comparable measures from the 3D motion tracking system. These data were then scaled to a 50th percentile adult male and corridors for the scaled trajectories were developed. Combined with the generic vehicle buck and validated trajectory capture and analysis methods, these results provide a means to evaluate the whole body kinematic biofidelity of 50th percentile male pedestrian dummies and computational models in perpetuity.
