Traffic accident reconstruction technology research and simulation realization

Accident reconstruction is not only an important way for responsibility identification or cause analysis in traffic accident but also an important step in study on traffic safety improvement. In this work, a type of physical analysis and an assumption model for traffic accident reconstruction, together with their respective realization methods, were introduced and described; simulation technology in two-vehicle collision accident was investigated; 2-Dimension impact calculation of velocity variations before and after collision was specifically given; computer simulation system was established to analyze and reconstruct impact velocities and vehicle behaviors according to data measured in accident scene; software application in practice was also briefly discussed.
