The investigation of car movement trajectories after contact in the case of collisions with stationary safety barriers

摘要

Car collisions with immovable obstacles are described. One of the most frequent cases is sidelong collision with road fencings and kerbs. Such road accidents are caused by the wrong choice of speed on road turns, skidding due to road and weather conditions, etc. Certain issues occur while investigating such road accidents: the place of the collision, the speed before the accident, the car movement trajectory after the collision etc. These issues are dealt with in this paper. With the help of computer software, different car accidents with road safety barriers have been modeled and the trajectories of car movement are defined in this paper.
