Here's a clip from Transportation Alternatives' documentary Contested Streets wherein Copenhagen is profiled and architect and urban planner Jan Gehl is interviewed and guides us through the last four decades of Copenhagen's transformation to one of the world's most liveable cities.

As Gehl says in the documentary:
"It's really wonderful to live in a city where every day when you wake up in the morning you realise that the city is a little bit better than yesterday. I've had this feeling now for over forty years."

The bicycle features prominently in the segment. Gehl says about Copenhagen:
"...one third go by bicycle, one third go by public transportation and one third in private cars. That is why we are the city in the western world that has least traffic - in any big million city [metropolis] - because the bicycle is carrying such a great weight in the total traffic picture."

Brilliant clip and interview with Jan Gehl highlighting Copenhagen's journey.
