Abstract
In this study, we propose a novel analytical model of the ship passage space evacuation accessibility based on the spatial analysis of a geographic information system (GIS). From the perspective of space accessibility, the proposed model analyzes the evacuation capacity of ship personnel. This model analyzes and measures the spatial shape, structure, and evacuation capacity of ship passages, along with the spatial factors affecting the evacuation behavior of people. Then, GIS spatial modeling and calculations are perfomed on the spatial network structure, spatial proximity of ship passages, and the evacuation behavior of people for the spatial analysis and safety assessment of the evacuation capacity of people in each ship space. Finally, from the perspective of spatial layout, based on spatial overlay calculations, the spatial feature information and potential spatial law information of evacuation accessibility for ship personnel are extracted. This study employs the M/V YU KUN as the experimental evacuation area for simulations. The results demonstrate that the proposed model exhibits good accuracy in the evacuation accessibility analysis of a ship's passage space. The results provide a good reference for future evacuation safety assessment and emergency decision-making of smart passenger ships and improve the efficiency of the emergency evacuation of ship personnel and passengers.
