Aiming at the improvement of emergency evacuation efficiency of cruise ship, three-dimensional emergency evacuation simulations were studied. As to the evacuation model construction, firstly, the road network model with width was proposed, based on which the algorithm of dense crowd passing in road sections with width, as well as the algorithm of evacuation path searching considering distance and traffic flow were proposed. Besides, an improved model of individual collision avoidance was proposed. As to the simulation system, taking a large cruise ship as an example, based on the three-dimensional ship model, the road sections model with width were built, and the spatial nodes such as rooms, restaurants and cinemas were connected to form a path network with width. then the path network of each floor was connected with the evacuation exit to form an evacuation topology network of the whole ship. With the support of the proposed path finding algorithm and the improved individual collision avoidance model, the simulation of emergency evacuation processes were realized and the cruise ship emergency evacuation three-dimensional simulation system was developed. Based on the three-dimensional simulation system, the paper focuses on the simulation of different escape exit layout and different evacuation strategies. By comparing and analyzing the simulation results, the key factors affecting the efficiency and safety of emergency evacuation of cruise ships are accurately identified, which can provide auxiliary support for the design of space layout and evacuation facilities of cruise ships and the optimization of emergency evacuation plan.
