Commission Decision of 5 June 2009 on the adoption of a common safety method for assessment of achievement of safety targets, as referred to in Article 6 of Directive 2004/49/EC of the European Parliament and of the Council (notified under document number C(2009) 4246) (Text with EEA relevance) (2009/460/EC)

2.1. Methodology for calculating NRVs

2.1.1. For each Member State and for each of the risk categories the NRV shall be calculated by applying in sequential order the following process:

(a)

calculation of the values returned by the corresponding measurement units listed in Appendix 1, by considering the data and provisions referred to in section 1.1;

(b)

analysis of the results of the process described in point (a), to check presence and recurrence of zero values for the FWSIs in the observed safety performances for the years concerned;

(c)

if the zero values referred to in point (b) are no more than two, the calculation is made of the weighted average of the values referred to in point (a), as described in section 2.3, and the returned value is taken as the NRV;

(d)

if the zero values referred to in point (b) are more than two, the Agency shall attribute to the NRV a discretional value to be identified by consulting the Member State concerned.
