Risk-based approach for the protection of land transport infrastructure against extreme rainfall
(2016)
The aim of the research project "Risk based approach for the protection of transport infrastructure against extreme rainfall RAINEX" is the development of a practical methodology for the identification and assessment of both vulnerable as well as critical transport infrastructures towards extreme rainfall events consequences. The developed methodology is based on expert knowledge and includes qualitative and semi-quantitative analyses regarding the assessment of the vulnerability and criticality of relevant transport infrastructures. The process chain from the spatial rainfall to the concentrated runoff in the river channel was shown to assess the local hazard resulting in the local risk. The main result of the project is a practice-oriented and applicable methodology and a comprehensive and well-developed security handbook.
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.
Various climate projections predict changing climatic parameters like temperature, precipitation, wind speed etc. for Germany. This could have severe impacts on road transport infrastructure as well as road traffic itself. At the Federal Highway Research Institute (Bundesanstalt für Straßenwesen (BASt) a strategy was developed to adapt roads and engineering structures to the impacts of climate change. The strategy "Anpassung der Straßenverkehrsinfrastruktur an den Klimawandel / Adaptation of the road infrastructure to climate change (AdSVIS)" comprises currently about 15 projects. On the basis of the identification of the hazards and the combination of the climate and road network data, the road transport infrastructure which might be affected is to be determined. Adaptation measures are to be developed for the identified risk areas and assessed as to their effectiveness. Special attention is given to international cooperation since climate change is a truly global challenge.
