A human finite element (FE) model was used to evaluate injury risks to pedestrian lower extremities in car-to-pedestrian collisions. A bending moment diagram and stress diagram of the tibia were introduced to investigate loading the leg. Using car models, it was demonstrated that the location of the lower absorber affects loadings on the tibia and knee significantly. The FE analysis using the TRL legform impactor was also conducted using the same series of car models. The injury criteria of both FE models were compared and suggested that the tibia stress and knee angle in the human FE model tended to increase with increasing of the injury criteria of the TRL impactor.
