Comparison of the landing kinematics of pedestrians and cyclists during ground impact determined from vehicle collision video records
Artikel i vetenskaplig tidskrift, 2018

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.
