NIST’s fire-routing AI stayed in simulation
Real buildings still posed unanswered questions.

NIST’s June 4, 2026 account described Safe Step, a reinforcement-learning model for single-storey fire-evacuation routes. It selected paths to reduce cumulative toxic-gas exposure, rather than simply choosing the shortest route. [1]
An earlier NIST technical-note page describes FD-Gen: it samples fire parameters to produce many simulator inputs. Such synthetic scenarios supply conditions a model can rehearse, rather than observations of successful evacuations. [2]
Multilevel layouts and interacting evacuees remained future work. Deployment would require sensors, reliability tests, regulatory approval and system integration. These were simulation results, not an operational evacuation service. [1]
