On Curitiba, Brazil’s former Mayor, Learning from Lerner:

Next year marks the 35th anniversary of a simple but transformative idea in urban planning and transportation: Curitiba, Brazil launched a surface bus system that behaves like a subway. Better than, in some ways. Double-articulated vehicles carry large volumes of commuters, passengers prepay their fare in glazed boarding tubes, designated lanes keep traffic flowing smoothly, and one bus trails the next by one minutes’ distance. Curitiba’s transit system was established with little municipal investment and at a fraction of the cost of subterranean excavation, and today it carries some 2 million people per day.
