'Green wave' for cyclists
It's just not fair. For decades cars have been whizzing through cites, unimpeded by constant stops at red lights. The phenomenon Germans call the Gruene Welle, or "green wave" (when a string of traffic lights turns green in sequence), has become an everyday occurrence in big cities, thanks to ingenious traffic control systems. Cyclists, however, constantly have to put on the brakes for red phases. Now, those days are over. Thanks to Siemens technology, cyclists can now experience the joy of the Gruene Welle on German streets.
