The field of safety in road tunnels has always been an important issue for operators, owners and the responsible authorities. After the tunnel accidents in 1999 the subject gained however in importance. On European level the Directive 2004/54 EC on "Minimum safety requirements for tunnels in the Trans European Road network" has been published. This guideline has to be implemented into national law by all Member States. According to the guideline all Member States of the European Community shall develop a methodology for risk analyses to be applied in certain cases. For Germany, a standardized methodology for a probabilistic quantitative risk assessment has been worked out.
Improving the security of critical road infrastructure is a major task for owners and operators of tunnels and bridges in the European TEN-T Network (Trans-European Networks of Transport) (European Parliament and Council 1996). Up to now, there has not been a systematic procedure for identifying and assessing critical infrastructure objects and selecting appropriate protection measures. The EC FP7 project SeRoN for the first time presents an innovative methodology in order to support road owners and operators in handling this complex task. This paper describes the methodology and project results in detail by giving an introduction into its practical application.
