Abstract
In recent years, with the development of national economic, China National Automotive holding a significant growth trend, which has also brought a sharp increase in road traffic accidents. How to deal with traffic accidents efficiently, fairly and accurately, especially when a truck crashes, it has become a pressing social problem. Therefore, this thesis, apply object collision theory to analysis the traffic accidents, research in the process of collision that the main issues involved, and give the process of collision calculating compliance with the relevant laws of physics, mechanics, and other aspects of kinematics calculated car Before the collision movement, and finally the actual participation of police departments in several traffic accidents caused by the collision and quantitative analysis, calculate the relevant data, with the police which given the conclusions of this study ,verify the collision theory in traffic accidents be applied.
