Abstract: Abstract Modeling and simulating building evacuation are effective to study human crowd and evaluate evacuation facilities. In most building evacuation models, occupants are assumed to have static information on the layout of the building. However, in reality occupants are able to obtain information from surroundings (e.g., alarms, exit signs or movement of other occupants). The information changes occupants’ decision-making and movement in turn. This paper considers information flow during evacuation and combines the information flow model with a modified social force model by updating the desired velocities of occupants. Inertia is also added for occupants to maintain their desired direction so that oscillations between different targets are reduced. Several cases are studied by simulation and results show that the information significantly affects the evacuation process and with the information model, the simulation is more realistic.
