This article considers animating evacuation in complex buildings by crowds who might
not know the structure’s connectivity, or who find routes accidentally blocked. It takes into account simulated crowd behavior under two conditions: where agents communicate building route knowledge, and
where agents take different roles such as trained personnel, leaders, and followers.
