Brach, R.M.; Guzek, M.; Lozia, Z.: Uncertainty of road accident reconstruction computations
Length of the stopping distance
The article demonstrates selected issues related to assessment of uncertainty in vehicle motion reconstruction during an accident. Five methods are described in this study: two deterministic methods (the total differential method and the extreme values methods) and three probabilistic methods (the Gauss method, the method based on descriptions of stochastic processes, and the Monte-Carlo method). Most of them are well-known for their application in assessing uncertainty. The methods are compared on the basis of example applications in the case of stopping process of a vehicle in rectilinear
motion. Also for the aforementioned case, the results obtained by means of various computational methods of vehicle motion (analytical and simulation models) are compared with experimental data.
