Multivariate Analysis MAIS or ISS as Injury Scale

The first research question regarding the development of injury probability models is which injury scale available in the datasets should be used for the models (Sect. 5.1). The MAIS and ISS are coded in GIDAS and PCDS. Fatalities are investigated separately, as they are distributed over a wide range of MAIS or ISS values. 

For the intended application of this work, it is important to verify the hypothesis that the explanatory variables could have an independent causal influence on injury severity for biomechanical or physical reasons. The variables associated with prior and evasive maneuvers of the vehicle as well as the pedestrian were omitted on the hypothesis that they have no direct causal relation, but are associated with injury
