New publication by PhD student Hossein Nasrazadani in the journal of Infrastructure Systems!
Prof. Bryan T. Adey's Chair of Infrastructure Management congratulates PhD student Hossein Nasrazadani on the publication of the article “Simulation-Based Stress Tests: Integrated Simulation Approach for Assessing Resilience of Transport Systems under Multiple Stressors” in the Journal of Infrastructure Systems.
In this article, Hossein Nasrazadani shows how to conduct detailed quantitative simulation-based stress tests on transportation systems. He shows this by presenting both an approach to conduct simulation-based stress tests and example simulation-based stress tests for a transportation system subject to potentially disruptive hydrometeorological events. He conducts three types of stress tests for the transportation system in the region of Chur, Switzerland, which is subject to heavy rainfalls that may result in floods and landslides. These include the stress caused by climate change leading to increasing the intensity of extreme rainfall events in the future, stress caused by uncertain future mobility behavior of people leading to excessive travel demand on the network, and stress caused by poor planning of the required resources for restoration interventions leading to having less resources for restoration than planned. He argues that conducting such stress tests makes it clear to decision makers whether or not a transportation system is sufficiently resilient against various stressors, and if not, gives clear indications as to how it could be improved.
This is the first published paper from Hossein Nasrazadani's doctoral thesis. His work builds on the previous work of former IM member Dr. Jürgen Hackl.
