Abstract:
This paper identifies sources of uncertainty in RSET
(required safe egress time) calculations, with focus on
data and modeling. A model for efficiently calculating
the range of egress solutions for a particular design is
presented. Three recommendations for future research are
proposed. First, future data collections and model
inputs should utilize distributions. Second, future data
collections should focus on emergency evacuation data
rather than fire drill data. Finally, modeling output
should utilize cumulative distribution functions to
visualize the range of egress solutions.
