This work develops a novel methodology for investigating dynamic evacuation route switching behavior and its influence on evacuation traffic assignment considering evacuees’ intuitionistic fuzzy perception and cognition of multitype multiattribute real‐time variable message sign (VMS) information. The methodology has three distinctive features. First, a link‐based VMS information utility model is developed. Second, two link‐specific dynamic escape speed models (DESMs), characterized by VMS information, evacuee attributes, and hazard‐related information, are proposed. Third, VMS information characteristics and the intuitionistic fuzzy method are integrated into route choice behavior models. The link‐specific DESMs are used to adjust the reactive DYNASTOCH algorithm to simulate emergency traffic evacuation. Results demonstrate that the proposed models are effective in characterizing not only dynamic evacuation route switching behavior (microscopic) but also network‐wide evacuation traffic performances (macro) under behavioral and information uncertainties.

在可变信息标志的影响下对疏散路线选择进行建模

这项工作考虑了撤离人员的直觉模糊感和对多类型多属性实时可变消息标志（VMS）信息的认知，开发了一种用于研究动态撤离路线切换行为及其对撤离交通分配的影响的新颖方法。该方法具有三个独特的特征。首先，开发了基于链接的VMS信息实用程序模型。其次，提出了两种以VMS信息，撤离者属性和与危害相关的信息为特征的特定于链路的动态逃生速度模型（DESM）。第三，将VMS信息特征和直觉模糊方法集成到路径选择行为模型中。特定于链路的DESM用于调整反应式DYNASTOCH算法，以模拟紧急交通疏散。
