“…However, in cadaver tests in which subdural and subarachnoid haematomas were produced, significant correlations were observed between AIS injury severity 2 and the corresponding HIC and 3 ms scores [20]. Similarly, from controlled experiments with cadavers compared to pedestrian head injuries, an abrupt transition from moderate to severe injury was found for HIC scores of 1100-1400, and a 50-60% probability of sustaining an injury of at least AIS3 has been predicted for a HIC of 1000 [21]. Furthermore, reconstruction of pedestrian accidents using an adult headform impactor in which the damage profile on the vehicle was matched to the accident case showed a strong correlation between HIC score and death [22].…”

“…Researchers found that vehicle type, collision speed, pedestrian gait, and walking speed could affect pedestrian head injuries. [2][3][4][5] Geometry and material of vehicle front end and pedestrian orientation were also believed to affect pedestrian head injuries as well. [6][7][8] Thus, pedestrian head injuries are most likely to be concerned in vehicle-pedestrian crashes.…”

There are a very limited number of reports studying on the dynamic response and injuries of pedestrian head in the scenarios with head hitting windshield. This study aims to investigate the significant factors that affect the dynamic response and injuries of pedestrian head through finite element-multi-body coupling simulations. Two finite element vehicle models and two multi-body pedestrian human models were used to build the coupling simulations. Orthogonal experimental design and analysis of variance were used for parameter combination and data analysis. This study demonstrated that the dynamic response of pedestrian head and HIC 15 were strongly associated with collision speed and pedestrian orientation. Vehicle type had a significant influence on the dynamic response of pedestrian head and HIC 15 , while there was no significant relationship between the dynamic response of pedestrian head and HIC 15 and the size of pedestrian human models. Collision speed, pedestrian orientation, and vehicle type should be prioritized over the other collision parameters in the study of head injury mechanism and reconstruction of vehiclepedestrian collisions in the scenarios with head hitting windshield.

“…Computational simulation of real life head injury accidents has been used for various purposes. Some have compared AIS (abbreviated injury scale) scores for real life injuries to HIC scores or other indices of injury calculated from the reconstruction [4,[30][31][32]. HIC and tolerance levels have been explained [46-47] and tabulated in Table 1.…”
