A traffic simulation system is accurately predicting jams on Germany's autobahn network up to an hour before they happen.
The system, developed by the University of Duisburg-Essen, takes into account real driver behaviours, for example, drivers changing lanes suddenly and forcing following drivers to brake hard and "bunch" in synchronised flow. However the system is in danger of becoming a victim of its own success as drivers modify their routes according to the predictions.
