CDU-YOLO: A Scene-Aware Real-Time Smoke and Flame Detection Framework for High-Rise Building Fire Safety

Reliable optical sensing of smoke and flames in high-rise buildings is challenging due to weak early cues, vertical smoke diffusion, facade occlusions, nighttime illumination, and fire-like urban interferences. We propose CDU-YOLO, a scene-aware real-time detection framework built upon YOLOv8n. Rather than relying on i...

Dynamic Fire-Evacuation Route Optimization in Complex Buildings Using Safe-Corridor-Guided RA-SSA

Dynamic fire evacuation in complex multistory buildings requires route planning across interconnected corridors, stairwells, transfer spaces, and exits while hazards, passage accessibility, and circulation capacity change over time. This study presents a risk-constrained method based on a safe-corridor-guided risk-awar...
