Olympic organizers staged a large-scale transit rehearsal across multiple venues, routing spectators through the same ticket checks, shuttle transfers, and rail platforms expected during competition. The exercise surfaced predictable friction points—crowd merges, signage confusion, and late-night train intervals.

Officials said the test is less about perfection and more about learning. Small changes—better wayfinding, staggered exit windows, and adjusted security lanes—can dramatically change how a venue feels to fans.

Transport planners warned that the biggest variable is weather. Heat or rain can slow movement and strain shelter space, making contingency planning as important as the baseline timetable.
