How Closing Roads Could Speed Up Traffic - The Braess Paradox

The Braess Paradox is an unexpected result from network theory. 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."
