When calculating the required cumulative width of emergency egress points for a permanent venue, what specific factor, besides total occupancy and exit factor, must be rigorously accounted for to ensure effective evacuation time, particularly for large crowds?

Beyond total occupancy and exit factor, the specific factor that must be rigorously accounted for is the effective flow capacity per unit of clear egress width. This concept recognizes that the physically measured width of an egress path does not always translate directly into a proportionally equivalent capacity for unimpeded flow, particularly for large crowds. Effective flow capacity per unit of clear egress width refe....
