Phantom Traffic jams are REAL!
Who hasn't been sitting on a highway and no one is moving – then when you drive on only to find there is no accident or reason for the traffic jam. Technology has helped to develop strategies to prevent PHANTOM TRAFFIC JAMS and they have found that it is all because of 'tail gating'. It's fascinating that research has been directed to animals (such as schools of fish and flocks of birds) that exhibit strategies of spacing because they don't have Phantom Traffic jams in their movements. They exhibit something called 'Bilateral Control' and technology is now being developed with Toyota to modify cruise control systems in cars so that 'Bilateral Control' can be achieved. Live Science
