Simulation-based approach to mitigate islanding impacts of landslides on the transportation network

Oregon is particularly susceptible to landslides due to its mountainous topography, geology, and climate. The occurrence of the Cascadia Subduction Zone event is expected to trigger multiple landslides, which can severely disrupt the road networks and cause severe islanding effects on communities especially along the coast. This research will simulate the occurrence of landslides and the required roadway recovery operations to provide decision-making support to mitigate islanding of communities.
