Most of the literature focuses on the impact of the single procedures and not on the impact of Directive 2008/96/EC as a whole. Therefore, given that the Directive has only recently entered into force, it is difficult to globally estimate and assign to the RISM procedures a specific impact, namely in terms of a reduction of road victims.
Before the implementation of the Directive, its impact assessment (EC, 2006) made reference to the thematic network EURORAP II2, which showed that, even in a country with a good safety record, deaths could be reduced by approximately 20% through a suitable and comprehensive road safety program.
The ROSEBUD project (EC, 20063) estimated that the reduction potential for implementing the four procedures to the TEN-T roads would have been a reduction of more than 600 fatalities and about 7,000 injury accidents per year.
This corresponded to 12%-16% of the fatalities and 7%12% of the injury accidents.
