A process for the assessment of infrastructure related risk due to natural hazards Hackl, Jürgen; Adey, Bryan T.; Heitzler, Magnus; Iosifescu-Enescu, Ionut; Hurni, Lorenz
The determination of network related risks for transport infrastructure systems, such as road or railway networks, is a challenging task. Due to such complex systems, it is generally impossible to abstract the global behavior from the analysis of single components, especially under conditions such as failures or damages. People who manage infrastructure have to handle these risks. The proposed overarching risk assessment process is constructed in a way so that computational support can be constructed in modules. This allows to couple the process with detailed sub-processes to achieve varying levels of detail in the risk assessment. The use of the overarching risk assessment process is demonstrated by using it to evaluate infrastructure related risk due to natural hazards for an example region in Switzerland.
