      abstract     = {In performance based fire safety design, ensuring safe
                      egress, e.g. by visibility of safety signs, is a crucial
                      safety goal. Compliance with the building requirements is
                      often demonstrated by simulations of smoke spread. Numerical
                      models like the Fire Dynamics Simulator generally compute
                      visibility as a local quantity using the light extinction
                      coefficient, without the consideration of the actual light
                      path to a safety sign. Here, visibility maps are introduced,
                      providing an approach for post-processing fire simulation
                      data. They indicate safe areas along egress routes, with
                      respect to visibility. At each location, the available
                      visibility is calculated using Jin’s empirical relation,
                      as an integrated value of the extinction coefficient along
                      the line of sight to the closest exit sign. The required
                      visibility results from the distance between those points.
                      Additional parameters like view angle or visual obstructions
                      are considered. The presented method allows for temporal
                      visibility assessment, e.g. in an ASET-RSET analysis.},
