Game theoretic modelling of evacuation dynamics — •Michalis Smyrnakis and Tobias Galla — Complex Systems Group, School of Physics & Astronomy, The University of Manchester, Manchester M13 9PL, UK

We model and simulate the dynamics of crowd evacuation in a game theoretic setting, based on extensions of the Helbing-Farkas-Vicsek model. In particular we consider situations in which agents evacuate rooms, bridges or corridors with several exits. Each agent then needs to make a decision on which exit route to choose, trying to optimise their own 'payoff', i.e. their chances of safe escape. Overall crowding and limitations in the geometry lead to potentially competitive strategic interaction between individual evacuees. Agents make their decisions based on information available to them (e.g. local degree of crowding, distance from the different potential exits, local direction of flow) and within the physical constraints imposed on them by other agents. The available information may change over time, and agents may revise their decisions as the evacuation progresses, using a myopic adaptation rule. We will also examine the impact of communication between pedestrians and how the number of agents with access to communication devices (e.g. mobile phones) can influence the total evacuation time.
