The purpose of this study was to investigate the landing kinematics (LK) of pedestrians and cyclists and to provide an analysis of the influencing factors. A total of 112 pedestrian cases and 51 cyclist cases with video information were analysed. The results showed that the pedestrians' and cyclists' landing kinematics depends on the vehicle front-end shape and impact velocity. In this LK1, the pedestrian/cyclist body had a clear rotation speed during ground contact. In this case, 71% of the cyclists and 39% of the pedestrians were found head firstly contact to the ground. In the most frequent LK2, the pedestrian/cyclist was thrown upward-forward and then landed without rotational speed (46% of all pedestrian and 49% of all cyclist cases). Research on the relation between the vehicle front shape and the LK of pedestrians/ cyclists can guide the safety design of a motor vehicle for reducing head injury risk
