Building codes specify means of egress mainly in terms of requirements concerning the arrangement of means of egress, egress capacities and maximum travel distances, derived on an empirical basis. Alternative solutions are increasingly substantiated by egress simulations and resulting evacuation times. Indicative values for the appraisal of calculated times are available, however, they refer to flow times only and no systematic evaluation of evacuation times for means of egress complying with code requirements has yet been performed.
