Abstract
This paper deals with an application of a computer simulation tool in engineering design and traffic safety. The subject of the research was a collision of a pedestrian and a passenger car. The target of the study was to develop a mathematical model enabling a sensitivity analysis and, if applicable, to create a tool for the design of an active restraint system. The research approach used a combination of experimental and mathematical methods. The created mathematical model was experimentally validated. Mathematical models ware developed in MADYMO environment.
