Abstract

This project develops a novel approach that couples an image-based structure-and-site-specific bridge fragility generation methodology with regional-scale travel demand and economic loss prediction models.  The established framework is being applied to real-life bridge networks of crucial importance, including the highway network surrounding the Port of Los Angeles, to assess resilience and economic losses at a high resolution. Due to its data-intensive nature, the proposed approach will capture and incorporate many details that are usually omitted in traditional analyses (e.g., HAZUS). It, therefore, promises to yield significantly improved accuracy in estimating economic losses and recovery after a major scenario event and the discovery of finer metrics of seismic resilience for transportation networks.
