Propagation of the Error in the Estimate of the Speed of Circulation of a Vehicle for Lost of Kinetic Energy 2002-01-2230
In the investigation of a catastrophe it is important the determination of the speeds of the units interveners. Therefore, generally, the reconstruction of sinister are made from a model based in the variables values measured in the sinister scene. In this work, the influence of uncertainties involved in restrained distances is investigated and the choice of a friction coefficient value, μ, is made to determinate the circulation velocity. As a conclusion, the uncertainties cause an important error propagation, which increases with decreasing values of μ, making the situation more critical when the estimated velocity value is around 11,11m/sec or (24,85mph), which has a critical understanding at the judicial area, for our regulation of the traffic (in Argentina).
