In order to investigate the pedestrian evacuation selection strategy in a multi-exit room with unknown exit opening status and to assess the effect of information transfer on movement status and evacuation efficiency during evacuation，an exit-finding SFM based on the information transfer mechanism was proposed. Firstly，A competition mechanism has been introduced into the social force model to improve the simulation's accuracy in reflecting real-life evacuation scenarios. The study then examined the evacuation process guided by rational and irrational strategies to investigate the impact of the herd effect triggered by information change on the overall evacuation. Finally，this paper introduces the information transfer mechanism to investigate the optimization effect of information exchange and cooperation on the escape path. The results indicate that the rational strategy is more robust for individual pedestrians in an emergency escape situation. However，from the perspective of group behavior，an optimal distribution of group strategies exists. Specifically，when approximately 25% of pedestrians choose the rational strategy，and the remaining 75% choose the irrational strategy，the evacuation effect of the whole group can reach its optimal effect. The introduction of the information transfer mechanism enables escaping pedestrians to effectively obtain critical escape information from the surrounding crowd，thus significantly improving evacuation efficiency. The facilitating effect of this mechanism is particularly evident in scenarios with fewer available exits.
