Simulation Pedestrian Flow Under Vertical Bottleneck Constraints: How Stair Configuration Affects Pedestrian Movement Efficiency

As a result of the geometric constraints stairs, pedestrian movement features on stairways are different from level ambulation. Therefore, it is necessary for us to consider stairs' three-dimensional geometry when we try explore how stair configuration affects efficiency. Based fundamental previous single-file experiment investigated flow under various configurations with an improved agent-based model. Our simulated indicates that both inclinations and tread depth step sensitive dynamic stairs. Generally speaking, decreases increasing slope When stairs increased 5, 10, 15 20 degree, evacuation efficiency dropped 5.8%, 12.8%, 19.3% 28.4%. Besides, effect total time not changed monotonously. Scenarios 0.3m size present optimal Other scenarios differ 3% 27.9% in terms time.
