Abstract Road flooding is a serious operational hazard for many low-lying areas across southern Louisiana. This hazard is especially acute for the regions emergency evacuation routes, which must be accessible for safe evacuation prior to an approaching hurricane. Emergency managers and decision-makers need additional tools regarding the factors and conditions that contribute to inundated roads to mitigate the risk of flooding during hurricanes. Numerous factors contribute to road flooding, including storm speed and direction, tidal ranges, wind speed, and storm surge. Many of these factors are deterministic and can be derived from available coastal weather services. Hurricane storm characteristics are modeled by the National Hurricane Center (NHC) and provided as a geospatial data product distributed for approaching storms at specified intervals. The fundamental objective for this study was to perform the research and develop techniques for quantifying the key factors that contribute to road flooding and a vehicles flood risk. This research will help decision-makers identify and assess the flood potential of vulnerable state-maintained roads, so they can develop mitigation and response strategies for these vulnerable routes. This study assessed the relationship between flood characteristics (e.g., flowing versus standing water and wind driven water) and vehicle class (e.g., size, weight, clearance, etc.).
