A research titled ‘Testing a framework for the efficiency assessment of road safety measures’ co-authored by G.Yannis, V.Gitelman, E.Papadimitriou, A.S.Hakkert and M.Winkelbauer was published in the Journal Transport Reviews in May 2008. An exhaustive review of standard methodologies and practices related to cost-effectiveness and cost-benefit analyses was carried out. Moreover, a number of case-studies are performed, concerning the efficiency assessment of various road safety measures in different countries. The procedures and barriers involved in the use of efficiency assessment techniques at different levels of decision-making are also highlighted, by means of feedback received during and after the various case-studies.
