Research On The Method Of Traffic Accident Fast Reconstruction

The traffic safety is an important aspect of the national economy development and the social stability, also is one of two basic tasks in road traffic management. The accident reconstruction is an important research content of traffic safety microscopic domain research. In this article, the author unifies the domestic and foreign research results, and does the research of the fast accident reconstruction method. This research introduces the ADAMS software, using the method of computer simulation to accomplish the fast accident reconstruction. This research in the ADAMS software platform has developed fast reconstruction module of road traffic accidents. Through establishing special-purpose menu, interface and parametric accident model for fast reconstruction, achieve dynamics simulation. Through contrasts between the displacement curve and the path displacement gathering from accident scene, we obtain the appraisal result. At the same time, we can achieve the fast reconstruction by the three dimensional animation effects in the analysis process. The important application of this research list as following:①Establish parametric accident model database based on reasonable simplification of accident models. We can establish the corresponding accident model in the different accident by changing corresponding parameters.②In order to guarantee the accuracy of accident reconstruction, the author scientifically adopts "the supposition-simulation-confirmation-appraisal" analysis step, and reasonably uses the parameter and evidence of the accident scene.③Establishments of models, simulation computation as well as the result analysis, all can be completed in the very short time. At the same time, this method operation is simple and easy to understand. Completely embody the advantages, such as simply, fast, and practical usable.④As to part of partial accidents' methods and the models, all is passed through the fast reconstruction analysis in actual cases, and is made contrasts between the analysis result and the empirical formula computation, which has confirmed the computer simulation method in the fast reconstruction analysis of traffic accidents with big validity and feasibility.
