The Paradox in the Wild

The Prompt

Find and document a real-world instance of the Braess Paradox — a case in which removing capacity improved system performance, or adding capacity made it worse. This may come from transportation (the 42nd Street closure, the Stuttgart road removal, the Seoul Cheonggyecheon restoration), electrical engineering, internet routing, or another domain. Describe the system, the intervention, and the counterintuitive outcome. If a published account exists, cite it; if you observe it firsthand, document your observation.

Completion Criteria

A description of the system, the capacity change, the observed outcome, and a citation or firsthand documentation.
