Simulation research on cruise evacuation based on improved social force model

The evacuation of cruise ship personnel under an emergency is an extremely complex process, and how to safely evacuate pedestrians is a difficult point in the study of cruise emergency evacuation. In this paper, a simulation model of cruise personnel evacuation is established through the AnyLogic simulation software based on the social force model, considering the congestion of pedestrians in the passenger cabin corridor in the face of emergency, and the effect of panic on the expected speed. By improving the social force model, the actual movement behavior of pedestrians is more realistically simulated. The simulation results show that by improving the social force model, in the cruise evacuation model, when the pedestrians in the cabin are very crowded in the corridor, they will be forced to insert the corridor for evacuation. Due to the panic generated by pedestrians, the evacuation speed of pedestrians farther from the exit will be faster than that of pedestrians closer to the exit, which improves the evacuation efficiency to a certain extent.
