- Abstract
- This paper describes an attempt to introduce occupant interaction with signage systems into evacuation simulation through the newly developed concept of the Visibility Catchment Area or VCA. In this paper we describe the concept of the VCA and how it has been extended to incorporate the presence of physical obstructions and termination distance. The VCA concept is then linked to a prototype behaviour model intended to represent the occupant's interaction with the signage system. The functionality and performance of the newly developed model is then demonstrated through the simulation of various evacuation scenarios within a hypothetical supermarket layout.
