ABSTRACT
Results of two physical simulations of motor vehicle collisions in road traffic have been presented, where the front of one vehicle hit a side of the other vehicle close to the front axle of the latter. The traces left on the road surface and on the vehicles in result of the collisions made it possible to carry out several simulations of the collisions under consideration with the use of the V-SIM program. Three possible versions of the course of the collisions, consistent with the traces left at the accident site, have been shown. For two versions of the collision, the pre-impact vehicle velocities were assumed as identical with those actually applied during the experiments; for the third version, they were calculated from the traces left. The vehicle velocity values thus determined were compared with the values of the actual velocities recorded during the experiments. The sources of, and reasons for, the possible errors made by the experts when carrying out the simulations of real vehicle collisions have been indicated.
