Determination of Vehicle Velocities and Collision Location by Means of Monte Carlo Simulation Method

摘要

In road accident analysis the problem of uncertainty of calculation results becomes essential particularly when modification of input values within the adopted ranges leads to diametric change of the answer to the question posed by the court of justice (e.g., "collision from the right-hand side of the center line" -"collision from the left-hand side of the center line," or "the accident could have been avoided" -"the accident could not be avoided"). The aim of the paper was to present a method of collision reconstruction calculation using the principle of conservation of momentum, the principle of energy conservation, and the principle of kinetic energy and work equivalence (energy balance) (Marquard), taking into consideration Monte Carlo simulation method. The applicability of the method in determination of distribution function for vehicle collision velocities was proved and, what is more important, its practical uselessness in determination of collision location.
