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.
