1 9 Conclusion What makes a road a sustainable safe road ? - A systemic approach (on the infrastructure / the driver / the vehicle) - Complemantary methodologies (preventive / reactive) - A structured reasoning (stake analysis / diagnosis / action plan / evaluation) - An action based on the understanding of accidents, adapted to the local context - An optimisation of public money (benefit/cost ratio) - A mix of a self-explanatory road (easy to understand) and a forgiving road (which gives users a chance to avoid an accident or to reduce the gravity of an accident) Titre et sous-titre.
