Topological analysis of a Coupled Weighted Panic Control Reflex (CWPCR) model in the context of terrorist attack

Abstract : A new model of weighted human behaviour in the context of urban terrorist attacks is introduced. In this context, one of the major challenges is to improve the protection of the population. In achieve this goal, it is important to better understand and anticipate both individual and collective human behaviour, and the dynamics of the displacements associated with these behaviours. Based on the recently published Panic-Control-Reflex (PCR) model, this new Coupled Weighted PCR model takes into account the role of spatial configurations on behavioural dynamics. It incorporates, via a bottleneck effect, the narrowness and the length of the streets, and thus the pressure and counter pressure of the crowd in dangerous and safe places. The numerical evacuation simulations highlight that, depending on their size, intermediate places or public squares modulate the dynamics and the speed of flow of the crowd as it evacuates to a safe place.
