Methodology Requirements
Road administrations have to determine poor road sections/itineraries where possible improvements will be highly cost-efficient.Methodology for accident analysis has to
be based on costs (Euros)
provide a ranking of sectionsfor further analysis

Safety Potential
actual accident cost per km
= accident cost per kilometre that could besaved by improvement measures
= accident cost to be compared withcosts for measures (cost-benefit analysis)
-target accident cost per km
=safety potential

Network safety management
• highlights worst performing sections/itineraries• provides a priority ranking of sections/
itineraries to be further analysed and improved• permits a direct comparison: potential savings
in accident costs vs. costs of improvement measures
• focuses on longer sections/itineraries complements Black Spot Management
• coincides with EU Commission’s definition

Where do we stand now?
Germany:• Safety potential map for motorways (since 2003)• Pilot for all interurban roads in one state (2006)
France:• Method applied at national level (2005)• Feedback on trials• 16 M€ available for 2006
