City of cyclists
4 of 10 from Denmark's pragmatic shades of green (photos)
Copenhagen calls itself the "City of Cyclists" and with good reason. The city has more than 350 kilometers (217 miles) of bike lanes, many of them cycle tracks that give cyclists a hard barrier between them, the pedestrian sidewalk, and the general road for cars. Some bike intersections, like this one, even have their own miniature traffic light.
