Information Spread during Building Evacuation Scenario with Long and Short-range Communication — •Mirko Kämpf and Jan W. Kantelhardt — Institut für Physik, Martin-Luther-Universität Halle-Wittenberg, 06099 Halle/Saale, Germany

Based on extended lattice-gas simulations with additional short-range and long-range interactions we study the spread of information between human agents during a large-scale building evacuation scenario. Our evacuation simulation tool utilizes established algorithms for the emotional and intelligence driven motion of human beings in a building and includes direct (short-range) as well as communication technology enabled (long-distance) information spread between them. We compare our results with those from simulations in an unrestricted geometry (free space) and for varying prevalence of long-distance communication. This way we study the impact of futures communication technologies on effective exit strategies during emergency evacuation. To detect phases (steady flow, panic, jam, etc.) and phase transitions in the system we apply detrended fluctuation analysis and return interval statistics to the simulation data. The results help us to define basic functional requirements for the underlying communication and network topology as well as to needed sensors.
