Error analysis of traffic accident reconstruction based on pc-crash

The parameters in the Software Pc-crash were analyzed in this paper. The work included: a car-car oblique impact model was designed, analysis and control variate method was used to acquire the key parameters and an orthogonal test was set to acquire the weights of these key parameters. Based on the parameters research the weights of the key parameters which influence the simulation result and the type of influence were obtained and used to seek the method for reducing traffic accident reconstruction Error. In addition, a typical traffic accident of four-wheel vehicle-two-wheel vehicle in China was reconstructed and confirmed the conclusion. The paper contributes to the further deep analysis about improving precision of traffic accident reconstruction in China with Pc-crash.
