An Emergency Egress Model Based On A Macroscopic Continuous Approach

Thomas Gasparotto, CNPP/LEMTA-Université de Lorraine

Abstract

Many modelling approaches can be used to assess evacuation time of buildings in fire situations. We present in this paper a new model, implemented in a collaborative work between LEMTA and CNPP, and based on a macroscopic continuous approach. First, the assumptions and algorithm of pedestrian movement model are detailed. Secondly, our model is compared to results from full-scale tests carried out without any fire constraints and to other egress models on typical test cases extracted from literature. Finally, the complete model (including fire stresses) is compared with FDS+Evac on a simple fire scenario.
