  2. French-German Elysée Treaty (1963) • Co-operation in • Politics • Public Services • Science Source : Bundesbildstelle, Berlin Exchange of experience on safety analysis of existing road networks

  3. National Guidelines

  4. ACCIDENT DATABASE ANALYSIS NSM Know Understand DIAGNOSIS AND DEVELOPMENT OF MEASURES RANKING AND IMPLEMENTATION OF MEASURES Act ASSESSMENT OF MEASURES Evaluate Improving Safety of Existing Road Networks

  5. 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

  6. Accidents 0 - 0,06 (n=1158) 106 veh•km 0,06 - 0,25 (n=3661) 0,25 - 0,42 (n=360) 0,42 - 0,72 (n=106) 0,72 and more (n=37) Accident Rate Accidentswith personal injuryon German motorways2002

  7. accident cost Accident Cost instead of Number number of accidents severity • joint analysis of accidents of different severity • consideration of different casualty structures • basis for cost-benefit analysis

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

  9. 1000 Euro km Safety Potential 50 - 105 (n=671) 105 - 250 (n=555) 250 and more (n=187) Accidents with personal injury and serious damage-only accidents on German motorways 2001-2003

  10. Ranking of sections/itineraries Basis for further analysis, development of measures and assessment

  11. Understand DIAGNOSIS AND DEVELOPMENT OF MEASURES RANKING AND IMPLEMENTATION OF MEASURES Act ASSESSMENT OF MEASURES Evaluate Improving Safety of Existing Road Networks Ranking of sections/itineraries NSM

  12. 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

  13. 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
