This paper will present a study of the potential for elevators to reduce occupant egress time and fire department access time for fires in tall buildings. Potential reductions in egress and access times will be compared for some specific cases where times for current procedures are available. The paper will review past research in elevator usage and the structure of existing models for elevator evacuation. From this review, the assumptions and limitations of the current elevator and egress models will be discussed, and future plans for improvement of the existing egress prediction techniques will be presented.
