Interaction of Pedestrians on Exit Selection

We investigate the interaction of pedestrians in an evacuation process in a room that has two exits, using the static floor field model. As a result of the simulation, a phase transition of pedestrian flow is observed when pedestrians tend to follow their neighbors, which causes a decrease of flux and an increase of travel time. In addition, we see that an obstacle in front of the entrance would be useful to repress the congestion caused by the interaction.
