AFSA Based Path Planning Method for Crowd Evacuation

Path planning is critical to the e‐ciency and fldelity of the crowd evacuation simulation. In this paper, we propose a new path planning method for crowd evacuation based on an improved AFSA. In our method, the crowd simulated by the artiflcial flsh swarm and the position of the crowd in evacuation scenario can be obtained through computing the position and direction of artiflcial flshes. In addition, we also introduce the PSO algorithm to calculate the velocity of artiflcial flshes in order to make the crowd evacuation simulation more realistic. Finally, we implement our method in difierent scenarios on the ACIS/HOOPS platform. The simulation shows that our method can enhance the e‐ciency and fldelity of crowd evacuation simulation.
