A recently completed study titled "The Price of Anarchy in Transportation Networks: Efficiency and Optimality Control" is throwing water in the face of conventional traffic flow theory, claiming fewer choices in route may lead to smoother traffic flow. The study posits that the choices made by individual drivers in an effort to reach their destinations as quickly as possible leads to the backups drivers face every day. By carefully limiting some of that choice, traffic may be moderated, resulting in fewer jams and reduced travel times. You know what else helps? Driving 62 billion fewer miles over nine months.
