Abstract
Hurricanes Katrina and Rita had a tremendous impact on transportation infrastructure and services in the United States. While other parts of the world have suffered greater losses from natural disasters, Katrina and Rita rank among the deadliest and costliest natural disasters in U.S. history (NOAA, 2014). They ravaged the Gulf Coast of the United States within a three-week period, with landfall first on August 29 then September 24, 2005. These disasters led to the largest mass evacuation in U.S. history, strained the region’s transportation infrastructure and services, and tested the effectiveness of state emergency management offices to respond to calls for transportation needs. Although there is a growing literature on the impacts of natural disasters on transportation infrastructure (Freckleton et al., 2012; Szyliowicz, 2013; TRB, 2008; Wolshon et al., 2005), there is scant research on emergency response to transportation needs, particularly unmet needs of disaster victims who face barriers to affordable transportation and services.
Objectives
This study fills this important gap through an unprecedented analysis of transportation-related 2-1-1 (non-emergency) disaster call data collected in real-time during the period of the hurricanes, allowing for the investigation of unmet transportation needs by location and disaster phases. We conducted a spatial and longitudinal analysis of 2-1-1 transportation-related calls in the US state of Texas to identify “hot spots” of unmet transportation needs.
