It states that adding capacity could actually slow down the speed of the network. Applied to highways, the Braess Paradox means the existence of some roads slows down traffic, or that closing some roads could speed up traffic. The Braess Paradox can also explain the \"Ewing Paradox\" in the NBA and sports--that a star player may hurt a team's offence. There are also applications in physics and how far a pair of strings stretch under gravity. The Braess Paradox is a result that individual drivers are seeking the fastest roads, and when all drivers make the same choices the roads are congested (this is an example of a Nash equilibrium from game theory). The inefficiency is a result of a lack of coordination, so this is known as the \"price of anarchy.\" References from the video 42st street closed traffic \u003ca href='http://www.nytimes.com/1990/12/25/health/what-if-they-closed-42d-street-and-nobody-noticed.html' target='_blank' rel='nofollow'\u003eimproved\u003c/a\u003e NYC Map Data: Google Maps (Bluesky, DigitalGlobe, Landsat, Sanborn, USDA Farm Service Agency) Boston Map Data: Google Maps (Google, Sanborn) London Map Data: Google Maps (Bluesky, DigitalGlobe, Getmapping plc, Infoterra Ltd \u0026 Bluesky, The GeoInformation Group) Closing roads in New York City, Boston, and \u003ca href='http://arxiv.org/pdf/0712.1598v4.pdf' target='_blank' rel='nofollow'\u003eLondon\u003c/a\u003e \"The Price of Anarchy in Transportation Networks.\" Hyejin Youn, Michael T.
