Abstract. In this paper we describe an evacuation modeling framework based on a graph representation of the scene. Typically such graphs (geometric networks) are constructed using Medial Axis Transform or Straight Medial Axis Transform. In our work we use Voronoi tessellation of a set of points approximating the scene (a single floor plan) along with the dual graph - Delaunay triangulation. Using these two graphs we extract not only the information about paths in the building, but also information about path widths and areas assigned to vertices. We discuss a typical density-based evacuation model coupled with a partial behavioral evacuation model within proposed framework.
