“Brasilia is not a city designed for cyclists or pedestrians. It’s a city designed for cars”. This phrase is very common to be heard by the Brazilians citizens. Despite that fact, it seems that the Government is changing that image of the city. The Government of the Federal District is implementing 600 km of bicycle paths until 2014 [1]. After this achievement, Brasilia will have one of the world's largest bicycle paths in the world.
The effort that the Government of the city of Brasilia is performing is the result of the perception that the current model of transport in which the overwhelming majority of the city residents use car as transportation is not a sustainable one.
