【 摘 要 】

Both traffic accident reconstruction and responsibility confirmation of traffic accident depend oncrash scene diagrammingand crash simulation. However,mistakenly recorded road geometry of the crash scene usually causes misunderstandings in the crash scene diagramming and thus the result ofaccident reconstructionis untrustworthy.Research has thus been continuously done to solve the problem. This study proposed a Google Map-based accident reconstruction system integrating functions ofcrash scene diagrammingand crash simulation. The modulus ofcrash scene diagramming includes positioning of accident location,Google satellite mapand Google Sketch Up to accurately present road geometry and accident vehicle position information. The modulus of crash simulation refers to the vehicle dynamic differential equations generated using the Newton-Euler formulation,and enhances with the calculation of momentum conservation in the collision to predict the vehicle dynamics after collision. The system developed in this study was validated using a real case.The results showed that acrash scene diagramming correctly drawn on theGoogle satellite map was an ideal platform to present the crush simulation, and help people understand or make a judgment for accident authentication.
