Within the framework of the BMBF-funded (German Federal Ministry of Transport and Digital Infrastructure) project "Resilient Road Tunnels (RITUN)", the increase in the resilience of road tunnels towards external events is being examined by the project partners: the Federal Highway Research Institute (BASt), ILF Consulting Engineers and the motorway authority for southern Bavaria.
PTV AG supported the project partners in this work by studying the effects on traffic of the unavailability or limited availability of two tunnels in the German road network and quantifying the associated macroeconomic costs. This work built upon the findings of previous projects, within which appropriate procedures were developed. For the two tunnels analysed, the effects of unavailability or limited availability were quantified for different scenarios that differ in terms of traffic restrictions and duration of these restrictions. The effects on traffic were determined using PTV Validate traffic model and an Excel-based control and evaluation module, which has been conceived and created during the project.
