Pole Side Impact Accidents in Germany(German In-Depth data analysis, GIDAS)

22/23th of March 2011, London DfT

Section “Passive Vehicle Safety & Biomechanics”

Objective

Support MUARC accident data analysis with German In-Depth data

Slide Nr. 2

Slide Nr. 3

No dominance of younger drivers for pole impacts in Germany [compared to AUS]

However, likewise in AUSPole casualties tend to be male driver(s)

Slide Nr. 4

Size und weight of passengers similarly distributed as in AUS

Side Airbag Fitment rate is still under consideration

No significant effects in injury risk modelling by now

Slide Nr. 5

More small and medium cars in Germany, no large carsinvolved in pole/tree

Slide Nr. 6

Distribution similarPole Impacts tend to be side centred

Showing higher crush depths

Slide Nr. 7

Distribution similarit does reflect less severe accident distribution in GIDAS

(as compared to AUS In-Depth data)

Slide Nr. 19

Less involvement of younger people in side pole impacts

Less heavy cars involved
