Hello, Diego. I have studied Curitiba some and seen a couple of interviews of the man that made it possible or at least is taking credit for it(former mayor). I can't remember his name. I am interested in finding out if the public transit is as effective as people want you to believe, and what types of policy were put in place that made it all possible. I realize you may not be familiar with the policy, but you may have ridden the bus or ridden a bicycle through town, a I would like to hear about that experience. Any info. that you have would be greatly appreciated. Thanks.
