The second BRT system in the world was the Rede Integrada de Transporte (RIT, "integrated transportation network"), implemented in Curitiba, Brazil, in 1974. The Rede Integrada do Transporte was inspired by the previous transport system of the National Urban Transport Company of Peru (In spanish: ENATRU) , which only had quick access on Lima downtown, but it would not be considered BRT itself. Many of the elements that have become associated with BRT were innovations first suggested by Curitiba Mayor architect Jaime Lerner. Initially just dedicated bus lanes in the center of major arterial roads, in 1980 the Curitiba system added a feeder bus network and inter-zone connections, and in 1992 introduced off-board fare collection, enclosed stations, and platform-level boarding. Other systems made further innovations, including platooning (three buses entering and leaving bus stops and traffic signals at once) in Porto Alegre, and passing lanes and express service in São Paulo.
