ManyJia, XiaoluFeliciani, ClaudioYanagisawa, DaichiNishinari, Katsuhiro present studies have illustrated the influence of obstacle on the egress efficiency of the crowd. In this paper, we have explored the influence of obstacle on both the egress efficiency and congestion status of pedestrians in a corridor with fixed width. A series of experiments with variable pedestrian number and obstacle size have been conducted with a wall-shaped obstacle set in the middle of the corridor. Results showed that the egress time would linearly increase with the pedestrian number while was not apparently affected by obstacle size. However, the variation of obstacle size would affect the congestion status of the crowd. To be specific, we have observed the congestion-sharing effect, which indicates the phenomenon that increasing the obstacle size could help share the congestion before the exit. Numerical analysis showed that the congestion-sharing effect would only be apparent when the pedestrian number is large enough. Furthermore, we have estimated the optimal obstacle size with the most balanced congestion status in the walking environment, which is expected to help with the actual design of obstacle for better congestion status.
