The Green Wave in Copenhagen from Colville Andersen on Vimeo.
The Green Wave in Copenhagen is in place with high levels of bicycle traffic. If you bicycle at 20 km/h, the traffic lights are timed so that bikes hit green all the way into the city center.
This video is taken along Nørrebrogade, a main arterial which (until a few weeks ago) was one of the main arterial roadways for automobiles, but now reserved for bike and bus through-traffic. While the East Bay bickers over exclusive bus lanes on Telegraph, Copenhagen is well on its way to reaching its goal of 50% bicycle mode share by 2015. Currently, they are at a whopping 36% — nearly even with automobile mode share.
