Study of human kinetic behavior and injury mechanism in pedestrian accident with human FE model

With the development of vehicles, occupant fatalities have decreased steadily over the decades, however, no significant change has been observed in pedestrian fatalities. In Japan, in-vehicle occupant fatalities in accidents were surpassed by pedestrians in 2008.It is believed to be necessary and urgent to decrease the pedestrian fatalities. Although pedestrian protection test procedures such as legform and headform impactor tests have been established, it is still difficult to estimate human injury level in pedestrian accidents, especially with the consideration of human kinetic behavior. In this research, by using human Finite Element model to simulate a pedestrian in an accident, human kinetic behavior is analyzed in detail. Because the head is the most frequently injury-associated region in severe pedestrian accidents, the mechanism of head injuries is also investigated in this research.
