Abstract Ship accidents worldwide continue to occur, resulting in an increasing number of casualties. For the safety of passengers on ships, the International Maritime Organization (IMO) regulates standards for evacuation analysis through SOLAS (International Convention for the Safety of Life at Sea). Until now, the evacuation time was calculated using a simplified evacuation analysis that assumes the movement of passengers as a flow of fluid as regulated by IMO. However, according to the revised IMO regulations in 2016, it is recommended to perform an advanced evacuation analysis that reflects the characteristics of each passenger similar to the actual situation, and the evacuation time should be calculated through this. Therefore, the behavior model for a passenger was proposed for the advanced evacuation analysis in this study. It was developed to make it easy to add, remove, and modify various characteristics of passengers by constructing a multi-channel behavior model. The characteristics of passengers generally include individual characteristics for escaping the shortest distance to a destination and group characteristics in consideration of surrounding people. Furthermore, if the ship is damaged, it may be flooded, and the attitude of the ship can change as time goes. Therefore, it was added as one channel in the behavior model for a passenger. In this study, the effectiveness of the proposed model was evaluated by applying it to various scenarios according to the IMO regulations and examples similar to the actual accident.
