POSSIBILITIES FOR ASSESSING THE PRE-COLLISION AND POST-COLLISION VEHICLES SPEEDS, IN THE EVENT OF SIDE COLLISIONS, BY THE QUANTITY OF MOTION CONSERVATION LAW
The paper evaluates, from a physical-mathematical point of view, the pre-collision and
post-collision vehicles' speeds, in case of side collisions, by preserving the amount of movement, taking into account the parameters resulting from the primary investigation of the scene. By reconstructing such road traffic accidents, the aim is to determine the kinematic quantities that influence the behavior of the vehicles involved in the accident, and to allow the analysis of the possibilities to avoid the collision. It also takes into account the situation in which the vehicles perform, in addition to the translational movement, a rotational movement around the vertical axes that pass through their centers of gravity. The developed working algorithm allows to change the input data (it can be applied to solve a large number of road traffic accident cases) and to obtain the results necessary for the reconstruction of such accidents. Thus, it is possible to establish the dynamics of this type of road accidents, which facilitates the assessment and comparison of different conditions taken into consideration.
