A key UoG contribution to IDIRA requires the development of urbanEXODUS (buildingEXODUS for large-scale incidents) in order to inform the procedural response to specific disaster scenarios. This requires both the enhancement of the EXODUS tool and an understanding of the subject matter being addressed. In order for the model to be suitably developed, an understanding of the individual response is required (e.g. evacuee behaviour) as well as the potential conditions that might be produced as these individuals interact and are influenced by the conditions around them (e.g. emergent crowd conditions). In addition, the physical and situational space within which these actions and conditions exist need to be considered to identify the factors that influence them and to represent these behaviours within a simulated environment. To address these considerations, the following broad areas of development have been identified.
