ABSTRACT: We consider a multi-modal constrained routing problem arising in emergency evacuation situ-ations. Given a three-dimensional geometric structure of the evacuation network related to an area, such as a high-rise building or a city area with tense population, an emergency evacuation route is a sequence of move-ments of people away from the threat or actual occurrence of a hazard (e.g., a fire or a hidden bomb) to a safe exit of the area. The multi-modality condition ...
