Uncertainty Analysis of Accident Vehicle Speed Based on Tire Marks

Abstract Accidents without video information often cannot obtain trace accurately, and it is difficult to accurately select parameters when using the tire marks formula, resulting in inaccurate results calculated during research analysis. To more authentic reliable analysis improve reliability authority of accident identification treatment, necessary reflect measurement error into conclusion calculation completely reliably, ensure that true value result within range theoretical error. Therefore, through Monte Carlo method Subinterval method, uncertainty speed carried out, vehicle restored which conducive handling personnel judge analyze speed.
