The European Commission has published the EU Methodology for Network-Wide Road Safety Assessment, as developed by NTUA, FRED and FPZ and adopted by the EU Member States. Τhis Methodology will assist EU National Road Authorities to carry out safety assessments of their road network easily and efficiently, as required by the EU Road Infrastructure Safety Management Directive. The Methodology comprises both a reactive (crash based) and a proactive (feature based) safety assessment, covering issues such as lane width, road curvature, junctions design, roadside layout and potential conflicts between motorised vehicles and vulnerable road users. Subsequently, the two assessments are integrated into a common safety rating system classifying all roads in a country. This way, Road Authorities will be able to identify priorities for future road safety interventions and investments.
