The article studies modelling a collision of a pedestrian with a car and the components of road infrastructure. With the study of the course of the road accident, there are analysed the possibilities of using a human body multi-solid model and the kinematic model for impact parameters reconstruction. The study also considers the possibilities of applying an analytic approach and road incidents databases, supplementary to computer simulation, offered by today’s programs used in road accident reconstruction. The study results demonstrate an application potential, and they can be used for road traffic safety enhancement. The effects of collisions with unprotected road traffic participants are most tragic and very expensive, hence considering the problem is this article is very important also for socioeconomic reasons.
