This paper proposes a modelling strategy to simulate a hospital evacuation. The capabilities of two commercial evacuation models, STEPS and Pathfinder, are explored to evaluate their ability to simulate this type of scenarios. This includes the study of the issues concerning the simulation of horizontal hospital evacuation (i.e. calibration issues, capabilities and limitations). A case study is presented in this paper by using STEPS model. Read More...
