Previous full-scale pedestrian impact experiments using post-mortem human surrogates (PMHS) and sled-mounted vehicle bucks have shown that vehicle shape relative to pedestrian anthropometry may influence pedestrian kinematics and injury mechanisms. While a parametric study examining these factors could elucidate the complex relationships that govern pedestrian kinematics, it would be impractical with PMHS tests due to the relative expense involved in performing numerous experiments on subjects with varying anthropometry. Finite element (FE) modeling represents a more feasible approach since numerous experiments can be conducted with a fraction of the expense. However, there have been no studies to date depicting kinematic validation of a human pedestrian FE model in full-scale collisions using different vehicle and pedestrian geometries. Therefore, this study used an FE model of the Polar-II pedestrian dummy that was previously validated against full-scale test data.
