The objective of this research project connected to the research package VeSPA is to combine the factors that affect accident events and to detect interactions among those effects. The first sub-goal is to expand the explanatory model on individuals and society on further dimensions (situation/infrastructure, vehicle, weather). The second sub-goal is do carry out multivariate analysis to detect holistic influence dimensions. The third sub-goal is based on the formulation of measures and interventions in order to support the accident reduction goal in Switzerland. As a result, the effectiveness will be analysed based on the explanation models and measures will be recommended and prioritized.
