The Surprising Impact of Braess' Paradox on Traffic and Systems

TLDRBraess' Paradox is a phenomenon where adding a road to a network can increase travel times. In the city of Seoul, tearing down a congested highway improved traffic flow. This paradox occurs because people are selfish and seek to optimize their own routes, leading to overall inefficiency. The same behavior can be observed in other systems, such as electrical circuits and water pipes. Identifying and mitigating the effects of Braess' Paradox requires computer simulations and analysis of network connectivity.
