This paper presents the methodology used to improve knowledge about vulnerable road users' accidents and more specifically pedestrians or cyclists.This work is based on a complete analysis of real accidents from three different approaches: in-depth accident investigation, numerical simulation with multibody model and experimental reconstitution with PMHS subject. Accidents chosen from an in-depth multidisciplinary investigation are numerically modelled using a multibody software. Then, a parametric study focused for instance on car velocity and victim position at impact is performed in order to find the best correlations with all indications produced by the in-depth analysis. Finally, the retained configuration close to the presumed real accident conditions is reproduced experimentally by a crash testusing cadavers. All results are finally compared in order to validate thereal accident reconstruction. This methodology is applied on two real accidents involving one pedestrian or one cyclist. (Author/publisher)
