Digital Twin of Buildings and Occupants for Emergency Evacuation: Framework, Technologies, Applications and Trends
Published in Advanced Engineering Informatics, 2025
This study, by analyzing literature from 2004 to 2025, proposes a digital twin framework for emergency evacuation that integrates buildings, occupants, and their interaction mechanisms. The research shows that the current related technologies are mostly at the L0 - L2 maturity level. In the future, multidisciplinary collaboration is required to optimize data integration, improve the performance of sensors and algorithms, integrate emerging artificial intelligence technologies while addressing data ethics issues, and enhance robustness of DT systems.
