What is it about?
This work studies the teenage pedestrian–sport utility vehicle (SUV) crash; injury to the vital parts of the body, such as the head and chest, and to the femur is evaluated. Head injury criterion (HIC) is used for the head, thoracic trauma index (TTI) criterion for the thorax in the case of side impact and 3 ms criterion in the case of frontal impact, while the force criterion is used for the femur. Particular attention is paid to the front shape of the vehicle, concluding that the frontal dimensions (bonnet angle, bumper height and bonnet height) are more important. However the teenage pedestrian in a lateral position is less prone to injuries in the head and chest, with respect to the frontal position; the pedestrian’s position has little influence on femur damage. In conclusion, a theoretical approach is shown, to highlight the influence of the vehicle mass on the pedestrian speed after the impact.

Why is it important?
The paper is important because contains an evaluation of the survival probability of the teenage pedestrian with the more used injury criteria. In addition the masses influence is evaluated by a theoretical approach, concluding that it is not negligible.
Perspectives
Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. In previous works the group has obtained interessant results in the study of teenage pedestrian impact with several vehicles, obtaining that the vehicloe mass is not neglegible and other.
