Crowd modeling analysis for all 16 World Cup 2026 venues across the U.S., Mexico, and Canada. Our work includes developing arrival and departure forecasts, simulating ingress/egress flow, and assessing emergency egress capacities using international standards such as the Green and Purple Guides. These models directly inform venue readiness, operational planning, and matchday safety strategies, ensuring a data-driven and globally aligned approach to managing the world’s largest sporting event.
