As a glimpse of a greener urban transport future, Germany has just opened the first five-kilometre (three-mile) stretch of a bicycle highway that is set to span over 100 kilometres. It will connect 10 western cities including Duisburg, Bochum and Hamm and four universities, running largely along disused railroad tracks in the crumbling Ruhr industrial region. the new track should take 50,000 cars off the roads every day, an RVR study predicts.
