This study proposes engineering countermeasures for lowering the possibility of pedestrian lower-extremity injuries. Pedestrian safety tests are commonly performed using anthropometric test device (ATD) subsystems. The lower legform is used to assess lower-extremity injuries during impact. In this study, a computer model of a mechanical surrogate for a pedestrian lower extremity is developed based on the finite element (FE) method. Results from the FE model indicate that the surrogate passes all certification tests proposed by the European Enhanced Vehicle-Safety Committee (EEVC), meaning that the model is biofidelic and suitable for the assessment of lower-extremity injuries due to car-pedestrian impact. In addition, a bumper system is chosen as an example to demonstrate safety evaluation by this pedestrian lower extremity surrogate. Based on the demonstration results, the safety of the bumper system is investigated.
