Faster-is-slower effects in traffic and production systems — •Dirk Helbing — Institute for Transport and Economics, TU Dresden

The faster-is-slower effect has been first discovered for panicking pedestrians, where evacuation times may increase, when a crowd is in a rush. Similar phenomena have now been discovered for other traffic and production systems. We will present various examples, analytical approaches to intermittent pedestrian flows and methods of self-organized flow optimization.The applications reach from intersecting pedestrian and vehicle streams over chip production upto harbor logistics. We will also address the optimization of productions processes and traffic light scheduling in urban traffic networks. The theoretical challenges of these problems and the economic potentials of related results can hardly be overestimated.
