摘　　要：在紧急情况下,疏散标志的清晰度和可识别性对于提升人们的应急效率至关重要。现有研究虽然关注了疏散指示标志的设计与可视性,但对应急照明下地铁疏散标志的易读性及显示角度研究不足。因此,本文旨在量化疏散标志的信息识别能力,利用视觉功效实验建立针对不同疏散场景人们对不同角度的标志信息的辨识率曲线,探讨方向标志在不同疏散场景下的最佳显示角度,以提升地铁应急情况下的疏散标志易读性。实验结果表明,不同显示角度对疏散标志的识别效率存在显著影响。基于数据分析,本文提出了站台区、疏散楼梯及扶梯等典型疏散场景的合理显示角度,同时也对应急疏散灯具设计进行了优化。研究结果不仅为地铁系统疏散标志的角度设计提供了理论支持,也对提升城市轨道交通系统的应急响应效率具有重要实际意义。In emergency situation,the clarity and recognizability of evacuation signs are crucial for improving people’s emergency efficiency.Although existing studies have focused on the design and visibility of evacuation signs,there is insufficient research on the readability and display angles of subway evacuation signs under emergency lighting.Therefore,this study aims to quantify the information recognition ability of evacuation signs.A visual effectiveness experiment is used to establish recognition rate curves for signs at different angles in various evacuation scenarios.The study explores the optimal display angles of directional signs in different evacuation context to enhance the readability of subway evacuation signs in emergency situations.The experimental results show that the recognition efficiency of evacuation signs is significantly affected by different display angles.Based on data analysis,the study proposes reasonable display angles for typical evacuation scenarios such as platform areas,evacuation stairs,and escalators,while also optimizing the design of emergency evacuation lighting fixtures.The research results not only provide theoretical support for the design of evacuation sign angles in subway systems but also have practical implications for improving the emergency response efficiency of urban rail transit systems.
