Abstract: While bus accidents tend to draw public concerns in China, much recent research has only focused on the analyses of car accidents due to relative high rates. However, the research dedicated itself to the scope of reconstructing and analyzing traffic accidents involving bus and quasi bus vehicle. Thus, the paper here is to represent a comprehensive method for the reconstruction of bus accidents, introducing analysis of human body injury as an auxiliary approach to verify the results of simulation in order to improve the accuracy of whole judgments, apart from using the technique of trajectory optimization as conventional reconstructions of car accidents, which ignore human body injury. According to clinical results and information collecting and concluding from the accident sites, the studies of body injury, which work as a kind of feedback in order to check and guide ordinary simulations, were carried out investigating the severity levels and dynamic response of hu!
man body under the given conditions calculated from common method. Within the method, the corresponding modifications of modeling, calculating and simulating need to be made, relating to the comparisons between predicted injury parameters and practical effects on victims. Through the demonstrations of the reconstructions and analyses of two real-life paradigms regarding bus accident, this paper indicates the general routing of the method for common cases. The research looks at applying two useful numerical reconstruction techniques, namely Multi-body body dynamics and trajectory optimization methods. With the help of two numerical modeling skills, preliminary results indicate that the combined reconstruction method can reflect the process of bus accident reasonably well. In comparison with conventional methods, the method provides more reliability as well as accuracy.
