Pavement Friction as an Input Parameter for Modelling Accident Process

The software modelling and simulation is classified among basic tools of accident analysis. Aside from active and passive safety systems, vehicle technical condition, road condition, current conditions within critical place proximity, differences of human abilities, also the limited knowledge of the real course of the whole traffic accident undoubtedly contributes to the complexity of processing of such simulation tasks (there is the lack of objective information). This work deals with the road friction properties as the objective boundary condition in simulations of vehicle motion. The aim of the work is to propose a method and determine ways of road surfaces modelling in the simulation environments. The method is based on current technological progress and expected development of modern technologies. The proposed method is experimentally verified.
