Pedestrian Dynamics During the Contact Phase with the Vehicle

Abstract

The paper presents a simplified mathematical model for the contact phase between the pedestrian and the vehicle during collision. After the primary impact with the lower limbs, the movement of the human body is influenced by factors such as vehicle speed during the impact, position / posture of the pedestrian and vehicle type. The secondary impact often causes pedestrian injury to the upper body as well as head trauma that is most often severe, even fatal. The study on the dynamics of the pedestrian hit by the vehicle is useful in order to understand the phenomena that occur; analysing the influence of different factors that determine the throw distance of the pedestrian is essential in conducting road accidents investigations.
