Abstract： Because the tradition traffic accident simulation selects the simulation parameter according to the experience, and revises repeatedly the simulation model through modifying the parameter, the simulation result has very big difference with real accident process. Especially it is difficult to confirm each input parameter Interval to simulation result's influence. Those cause the result to lack the credibility and the persuasive power. This article has discussed how integrates through the traffic accident simulation and the optimized computation to the accident simulation result carrying on the reliability analysis, obtains the input parameter confidence interval distribution. Through the Car-Pedestrian Collision traffic accident actual case, the input parameter confidence interval analysis result indicated that: In each confidence interval, the accident reappearance result reliability and the output parameter distribution conforms to the collision process rule, and can reflect really the input parameter change to the influence of the reappears result.
