Riskanalys och tunnlar – hur bör händelser med låg sannolikhet och hög konsekvens hanteras?
Events that can be described as high impact and low probability (HILP-events) have been proven difficult to deal with, for example background data often is sparse. Due to the construction of traffic tunnels these events need to be taken into consideration. A tool for doing this is risk analysis, and with this tool the events can be identified and handled with a quantitative or qualitative approach
