Everything's green in Duisburg. Well, almost. That's because many green dots and only one red one can be seen on a huge display that shows the city's street network. Every dot represents a traffic light. Green means everything is working perfectly; red means the opposite. Bakir Bijedic-Hoffmann, Head of the RCM Support Center in Munich, clicks on the red dot. The display tells him that one of the traffic light's red lamps has burned out. This is not a big problem, because traffic light systems generally have at least two traffic lights for each direction or two light bulbs for the red signal.
