摘　　要：灾害事故的突发性和危险性使研究人员难以安全复现现场条件从而获取人员疏散数据。搭建虚拟疏散试验环境,模拟再现真实疏散场景中的多人实时交互,组织验证试验并对比真实试验数据,证实虚拟试验可重现真实环境中人员路径选择特征。进而设计并开展多人在线虚拟试验,研究可用出口数量差异对不同规模人群路径选择的影响。结果表明:人员更倾向选择出口信息明确的路径,这种倾向在人群规模不同时略有差异;当两条路径上可用出口数量均已知时,人员倾向于选择可用出口数多的路径,且选择占比随可用出口数差值D增加而增加;当存在可用出口数未知的路径时,人员在已知可用出口数N较少时倾向于探索未知路径,选择出口信息已知路径的占比随N增加而增加。Accidents often occur unexpectedly,making it difficult to gather real-time evacuation data from individuals at the scene.Moreover,due to the inherent dangers and the need to protect participants,it is challenging to safely conduct experiments that replicate such scenarios.Therefore,modern computer technology is used to create virtual experimental environments that accurately reflect real-world conditions for conducting such experiments.This 3D virtual environment simulates various scenarios and accident types,supporting both individual and multiple participants through a local area network.A multiplayer online evacuation experiment,based on real-world scenarios,was designed and organized for comparative analysis of route choice.The results indicated that this virtual experimental environment effectively replicated the route choice behaviors observed in real-world settings.Following this,a series of controlled multiplayer online virtual experiments were designed and conducted to study the impact of incomplete exit information and varying crowd sizes on route choice behavior.The results showed that participants were more likely to choose a path with clear exit information.When the number of available exits on both paths is known,or when one path has an unknown number of exits,both the difference in the number of available exits(D)and the known number of exits(N)significantly influenced route choice.As the values of D and N increased,the proportion of participants choosing the path with more exits,or with a known number of exits,rose from 64.24%and 33.33%to 80.63%and 70.83%,respectively.Overall,there was no significant correlation between crowd size and route choice results.However,when the crowd size was moderate(20 pedestrians),route choice showed a significant correlation with both D and N values.Additionally,when confronted with scenarios involving paths with an unknown number of exits,participants tended to explore the unknown path.However,as the known number of exits(N)increased,individuals were more inclined
