Abstract

The present master’s thesis investigates the effect of exit configurations on evacuation performance in outdoor mass gatherings, using advanced agent-based simulation techniques. The study is inspired by safety and emergency preparedness in Danish festivals, which often attract large crowds in open-air environments. To this end, simulations are conducted using Pathfinder software to evaluate how exit width, placement, and clustering impact egress times and congestion levels. The response surface method is applied in order to formulate the egress time as a function of statistically significant exit confirmation parameters. The results indicate that while wider exits significantly reduce evacuation time, the optimal arrangement involves a balanced trade-off between exit width and the number of available exits. Exit clustering emerges as a critical factor, influencing crowd flow dynamics and the formation of bottlenecks. Practical recommendations for event organizers include optimizing exit placement and width to enhance evacuation efficiency while maintaining compliance with safety regulations. The findings underscore the importance of simulation-based analysis in improving the safety and operational planning of mass gatherings, with implications for policymakers and festival organizers in Denmark and beyond.
