NIST has unveiled an AI model designed to optimize fire evacuations by identifying the safest escape routes in real time. The core problem is that traditional exit signs often lead people toward hazards or bottlenecks, which can increase danger during emergencies. To solve this, the new AI model analyzes building layouts and fire sensor data to provide dynamic, step-by-step guidance. This system effectively directs people away from smoke and fire hazards, ultimately improving survival rates and making public infrastructure significantly safer.
