Curitiba
Because it is a planned city, the administration uses a rigid plan for growth, aiming to facilitate the use of public transport. The idea was to organize the city along transport corridors. The buildings are close to major bus lines. The rule is simple: buildings with more than eight floors can only be built in the first block, near the corridor. Buildings with less than eight floors, in the second block, and in other, smaller buildings and houses. This encourages the system bus, that is widely used, reducing the number of cars.
