Abstract：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.
