Description: The need to accelerated bridge construction (ABC) activities due to flooding has complex interdependencies with many physical, social, and environmental factors in urban areas. Flood-related factors can also contribute to bridge scour, the biggest cause of bridge failure in the United States. This Seminar presents a GIS-based, multi-criteria decision analysis framework in to assess the vulnerability of urban areas against flooding and socio-environmental factors and risk of bridges considering structural and traffic conditions. The final product is a risk map that shows an overall risk factor for each bridge. Application of the framework will be demonstrated for existing bridges in Miami-Dade County, Florida. The proposed framework is systematic, structured, and flexible, making it adjustable to be implemented in different geographic locations. Hence, it can be used by state DOTs as a practical, risk-based decision support tool for prioritizing bridge rehabilitation activities based upon technical, social equity, and environmental justice criteria in the presence of limited budgets.
