Abstract:The movement of freight vehicles during hurricane evacuations remains an underexamined aspect of emergency transportation planning. While extensive research has been conducted on personal vehicle evacuations, freight movement patterns before, during, and after hurricanes have received limited attention. This study investigates vehicle movements by classification, with a focus on freight, during the evacuations and reentries associated with Hurricanes Irma (2017) and Michael (2018). The research utilizes traffic volume data from Florida’s statewide continuous-count stations to analyze spatial and temporal travel patterns across vehicle classifications. Key findings reveal that commercial vehicles exhibit distinct evacuation behaviors compared to personal-use vehicles. Notably, truck traffic patterns changed earlier and persisted longer than personal vehicle evacuations, suggesting that commercial operators respond differently to impending storms. Additionally, results indicate that commercial use vehicles may have underutilized or avoided rest areas, possibly due to closures or other operational constraints. This behavior could imply extended driving hours and distances for truck operators, potentially impacting safety.
