Abstract

This paper presents the wayfinding and door selection algorithm used by the Pathfinder egress simulator. The development of Pathfinder’s Locally Quickest algorithm will be discussed along with unforeseen consequences and one promising, but discarded, initial attempt. Validation of this new model is presented as well as characteristics of the third party research that make simulator validation possible.
