Critical Transportation Infrastructure Identification and Prioritization Under Flooding Risks

摘要: Climate change is challenging human society with frequent and serious impacts. Transportation infrastructures in the coastal area are especially vulnerable to flood impacts from storm surge, sea level rise, intense precipitation, so on. infrastructure maintenance retrofit plan should give priority critical whose failure will have important on network performance. In order better inform decision makers of criticality transportation case flooding, this study explores an accessibility-based prioritization methodology identify rank under flooding risks. particular, evaluates network-wide based increase travel cost taking traffic congestion, trip cancellation, location importance into account. The applied road Hillsborough County, Florida. Light detection ranging elevation data, network, zone-based population data County processed for analysis. approach yields results not only at risks but also most regions as a result inundation. authors show that some its surrounding areas, while become much broader region. further demonstrate more if it serves people area.
