Abstract

After 9/11, the Indian Ocean tsunami and Katrina, the production of papers related to mobility simulation in evacuation conditions has significantly increased. Several topics have been developed, but in most cases these are implemented considering an isolated and non-system approach. The aim of this work is to present the major contributions which consider evacuation conditions, classified in respect of simulated user decisions, and to highlight the necessity of a system framework in this analysis. Keywords: evacuation conditions, demand model. 1 Introduction In evacuation conditions, demand models specified and calibrated in ordinary conditions cannot be directly applied. Various specifications can be considered in relation to the type of events, which may be classified in relation to [1–5]: ● effect in a transport system, which may be on demand, supply or demandsupply interaction; ● event kind, which can be natural or anthropogenic; ● effect in space, which can be punctual or diffuse; ● effect in time, which can be immediate or delayed. In this work we propose a classification of literature models which simulate evacuation conditions and are demand-focused in relation to the effect in the transport system. We consider models that deal both with natural and anthropogenic disasters.
