Analysis of pedestrian-tram collision phenomena: possibilities of simulation models validation

The article deals with the validation of the pedestrian simulation model as the initial study for future virtual testing of the tram front-end. The vision of virtual modeling approval is the main motivation of the study. The biofidelity of existing models was the subject of volunteer tests. The data are utilized for assessment of both adapted real anthropomorphic test device and presented simulation models created by means of commercial computer systems LS-DYNA and RADIOSS. Two basic tram front-end geometry were used in the pedestrian collision simulations. The resulting physical data are presented. The article demonstrates the complexity of the problem under study [Margaritis 2007] and confirms the correctness of the segment testing used in the automotive area.
