  We numerically study the impact of impulse stops on pedestrian flow for a
straight corridor with multiple attractions. The impulse stop is simulated by
the switching behavior model, a function of the social influence strength and
the number of attendees near the attraction. When the pedestrian influx is low,
one can observe a stable flow where attendees make a complete stop at an
attraction and then leave the attraction after a certain amount of time. When
the pedestrian influx is high, an unstable flow is observed for strong social
influence. In the unstable flow, attendees near the attraction are crowded out
from the clusters by others due to the interpersonal repulsion. The expelled
pedestrians impede the pedestrian traffic between the left and right boundaries
of the corridor. These collective patterns of pedestrian flow are summarized in
a schematic phase diagram.
