Pedestrian throw distance can be used to evaluate vehicle impact
speed for wrap or forward projection type pedestrian collisions. There
have been multiple papers demonstrating relationships between the
impact speed of a vehicle and the subsequent pedestrian throw
distance. In the majority of instances, the scenarios evaluated focused
on the central width of the vehicle impacting the pedestrian.
However, based on investigated pedestrian collisions, the location
where the pedestrian has engaged with the vehicle can and does
significantly influence the throw distance (and projection) and
subsequent impact speed analysis. PC-Crash was used to simulate
multiple pedestrian impacts at varying speeds and vehicle impact
locations, creating pedestrian throw distance impact speed contour
plots. This paper presents the pedestrian throw distance impact speed
contour plots for a range of nine vehicle types.
The purpose of this paper is to illustrate that there is an effect on
impacted pedestrians' throw distance and post impact direction due to
both the vehicle shape and point of impact on the vehicle. However
the effect is not yet validated by means of physical tests and further
research is required.
