Abstract


The process of recognition of road traffic accidents , the accident occurred when an important basis for the identification of the vehicle speed accident identified need . The speed of the confirmation of the accident is to form the necessary link in the chain of evidence of the accident process accident side driver whether evidence of the existence of irregularities in the speed control , but also for handling the case agency . The calculation of the speed of the accident have been calculated , during speed identification based on the morphology of the accident and the collection of information and then combined with the actual selection of a reasonable method of calculation . This paper first discusses the theoretical basis collision mechanics car front , rear-end , vertical sides and oblique collision condition of mechanical laws and solving method , in dealing with the complex problem of accidents , how to take full advantage of the original model simplification exploration docket information theoretical analysis estimates were identified automobile accident speed and impact angle Mechanics certain technical way . Then use the classic collision mechanics method , combined with the characteristics of the car crash accident , several common practical formula of the accident vehicle speed , and a detailed study of the extent and impact of each use of the formula and the values ??of the parameters involved level. Actual collisions , it is proposed in the analysis to consider the various factors affecting the combined effect of the vehicle motion , can be used a variety of calculation methods mutual authentication . Come through a lot of research and analysis for the obvious brake traces and skid marks, and also a lot of fallout, accident , priority should be given to using the brake marks or skidding traces calculate vehicle speed , and then take advantage of the fallout, further validation .
