Optimizing group egress times reduces crowd density without significantly increasing total evacuation time. This system improves pedestrian flow and comfort in complex facilities.
Area of Science:
- Engineering
- Computer Science
- Social Science
Background:
- Pedestrian facility design has improved safety, but congestion and inefficient infrastructure use persist.
- Research often focuses on extreme crowd scenarios, neglecting methods for non-critical conditions.
- Crowd sensing technology is underutilized for real-time crowd management.
Purpose of the Study:
- To develop a system for computing optimal egress times for groups in complex facilities.
- To demonstrate that optimizing individual group egress times can reduce overall crowd density.
- To improve comfort and reduce close contact during crowd events.
Main Methods:
- A system was developed to calculate optimal egress start times for distinct groups.
- A small-scale experiment was conducted to test the system's components in a simplified scenario.
- The system utilizes crowd conditions to inform egress time computations.
Main Results:
- A 5% increase in total egress time enabled a 35% reduction in maximum crowd density.
- Optimized egress timing significantly reduced density without substantially impacting overall evacuation duration.
- The system proved effective in a controlled experimental setting.
Conclusions:
- Accurate computation of group egress times can effectively manage crowd density.
- This approach enhances crowd comfort and reduces close physical contact.
- The developed system offers a practical solution for improving crowd flow in complex facilities.
