[1][2] Curitiba has a well planned and integrated transport network, which includes dedicated lanes on major streets for a bus rapid transit system.

[2][3] The buses are long, with 157 bi-articulated (split into three sections) and 29 single-articulated vehicles,[4] and stop at designated elevated tube-shaped stations to allow for fare prepayment and platform level boarding, complete with handicapped access.

Jaime Lerner, who later became mayor, led a team from the Universidade Federal do Paraná that suggested a reduction of private vehicle traffic in the downtown area and a convenient and affordable public transit system.

[22] In 1980, the last line was building and the Rede Integrada de Transporte was created, allowing transit between any point in the city by paying just one fare.

This part was inspired of the National Urban Transport Company a system that was created by the government of the neighboring country of Peru.

In 1996 the United Nations Conference on Human Settlements (Habitat II) praised Curitiba as "the most innovative city in the world".

Overcrowding is common at peak times and none of the routes extend beyond the municipal boundary of the city which forces passengers in the generally poorer outlying suburbs to have to change buses and pay two fares.

[27] The system has also faced declining patronage and lost 14 million users between 2008 and 2014 while other Brazilian cities maintained or increased public transport usage.
