Determinants of the severity of passenger vessel accidents Academic Article uri icon


  • This study investigates determinants of the number of injured, deceased and missing occupants and the damage cost of passenger vessel accidents that were investigated by the US Coast Guard for the years 1991-2001. Negative binomial and Poisson regression estimates suggest that: (1) passenger-freight combination vessel accidents incur greater injuries than other types of passenger vessels, (2) deaths are greater when precipitation weather and poor visibility exist and (3) missing occupants are greater for capsize accidents and larger the vessel. The damage cost per vessel gross ton is less for ocean cruise and steel-hulled vessels. The major conclusion of the study is that human (as opposed to environmental and vessel) causes of passenger vessel accidents result in increases in the number of injured, deceased and missing occupants.
