Abstract

To alleviate the congestion of passenger ship personnel at the emergency evacuation exit, crowd dynamics experiments were combined with personnel evacuation simulation modeling, and baffles at different angles to the wall were set up at the exit to improve the efficiency of personnel evacuation. Firstly, crowd dynamics experiments were designed and conducted for different exit layout configurations to collect data on human evacuation movement, and trajectory tracking technology was employed to extract movement trajectories and analyze evacuation efficiency under different layout configurations. Secondly, based on the social force model and by using ship layout parameters from the SAFEGUARD fullscale evacuation project, a full-scale evacuation simulation model for passenger ship was established and validated for its effectiveness. Finally, taking the exit layout configuration of the crowd dynamics experiment as input to adjust the layout of the passenger ship exit in the established simulation model, the influence of the exit layout configuration on personnel evacuation efficiency on a full-scale evacuation platform was verified and analyzed. Results show that when a baffle is installed at the exit and the angle between the baffle and the wall is 30°, the evacuation situation is optimal, while the evacuation efficiency and congestion relief rate are increased by 6.57% and 11.21%, respectively. The research results can provide decisionmaking basis and technical support for emergency management of passenger ships and ship design.
