ASPECTS REGARDING THE NUMERICAL MODELING OF THE TRAFFIC ACCIDENTS WITH MUTUAL VISIBILITY BETWEEN VEHICLES
This paper evaluates the kinematic measures of a car accident with mutual visibility of the vehicles from the physical-mathematical perspective taking into account the parameters resulting from the primary research of the scene of the accident. The reconstruction of such accidents shall determine: the speeds of the vehicles before and after the collision based on the weight of the vehicles, based on the angle between streets (the angle between the longitudinal symmetry axes of the vehicles); the analysis of possibilities of avoiding the accident. The numerical modeling developed can be used to solve a large number of side-impact vehicle-vehicle accidents in order to establish the dynamics of their occurrence. The algorithm allows exchanging the entry data and getting results with graphical interpretation for various situations of side-impact between vehicles which facilitates the estimation and comparison of the various conditions taken into account. The use of computerized analysis with its advantages (reduction of calculation time, simulation of various accident situations, etc.) becomes a useful and necessary tool for the technical experts and engineers who carry on their activity in the field of reconstruction of car accidents and development of car security systems.
