A pedestrian evacuation ABM in a complex environment based on Bayesian Nash Equilibrium

This research proposes an updated evacuation model incorporating Bayesian Nash Equilibrium (BNE) within multi-agent systems. It augments the rationality of pedestrian decision-making processes and improves the evacuating behaviours of pedestrians. Recent research found that BNE pedestrians could evacuate more quickly by avoiding clogged areas, closely matching the pedestrian evacuating behaviours in reality. This paper extends this work by introducing a number of diamond- shaped barriers in the model to evaluate whether and how BNE affects the pedestrian evacuation process in more complex scenarios. It provides a detailed introduction of the updated simulation model and identifies several limitations and potential research directions.
