Division 3.2.5 The fourth assessment step shall verify whether the number of significant accidents per train-km, with respect to the previous years, remained stable (or decreased). The criteria for this appraisal shall be whether there has been a statistically significant increase in the number of relevant significant accidents per train-km. This shall be evaluated by using an upper Poisson tolerance bound which will determine the acceptable variability based on the number of accidents that occurred in the different Member States.F1
