Modeling Information Sharing Process Between Pedestrians in Evacuation Simulations

Knowledge and communication are key aspects of interactions between humans. If the authors consider the evacuation from a facility with broken escape routes, people will likely share the information with others who run into coming from the opposite direction and heading towards the broken route. In the case of a dense crowd, the information about the state of an escape route for instance needs some time to reach the people at the back. In this contribution the authors model the process of gathering and sharing information. The authors use a variation of the Sznajd missionary model for propagating the information, where neighbours have a probability of changing their opinion. In addition the authors introduce different traits of pedestrians steered by a risk awareness probability. With lower risk awareness, people are more probable to accept the new information given by others. People with a higher risk factor will only trust information they have gather themselves. The concept has been demonstrated on scenario with multiple escape routes. Two of the escape routes become unavailable during the simulation. The influence of the propagation speed and the personality traits of pedestrians on the overall evacuation times has been investigated. The authors show that the compliance rate to new information has a positive impact on the egress time. The propagation speed plays a major role when the evacuees are less refractory to the new information. In the other case, the dominant factor is the percentage of evacuees refusing new information.
