The objective of the present study is to synthesize and investigate usingthe same set of sixty-one real world accidents the human head injury prediction capability of the HIC and the HIP based criterion as well as the injury mechanisms related criteria provided by the SIMon and the Louis Pasteur University (ULP) finite element head models. Each accident has been classified according to whether neurological injuries, subdural haematoma andskull fractures were reported. Furthermore, the accidents were reconstructed experimentally or numerically in order to provide loading conditions such as acceleration fields of the head or initial head impact conditions. Finally, thanks to this rather large statistical population of head traumacases, injury risk curves were computed and the corresponding regression quality estimators permitted to check the correlation of the injury criteria with the injury occurrences. As different kinds of accidents were used,i.e. footballer, motorcyclist and pedestrian cases, the case-independencycould also be checked. As a result FE head modeling provide essential information on the intracranial mechanical behavior and, therefore, better injury criteria can be computed, especially for neurological injuries.
