The European Directive 2008/96/CE requires member states to establish and implement procedures related to road safety impact assessments, road safety audits, the management of road network safety and safety inspections. In the Directive, great emphasis is given to road Safety Inspections (SI) as an effective tool for the safety management of existing roads. This chapter presents an overview of road SIs tools in Europe and discusses the new software tools designed to improve efficiency and safety during SI and to carry out actual values of RI. It describes the prioritization and optimization procedures based on risk index (RI) to identify the intervention strategies that produce the highest accident reduction and/or the highest safety benefit‐cost ratio. The optimization process is carried out by means of a total enumeration algorithm, evaluating the number of years in the analysis period and costs for each road segment and each strategy adopted.
