São Paulo Transporte (SPTrans) (English: São Paulo Transport), is the name adopted on March 8, 1995 by the municipal local government which aims to manage the public transport system with buses in São Paulo. Until 1995, it was known as Companhia Municipal de Transportes Coletivos, which, when translated from Portuguese to English, it is the Municipal Public Transport Company. All bus lines are operated by concessionaires under the supervision of SPTrans, providing business planning and management of public transport. The SPTrans issues work orders for each line of operation, including setting paths, hours of operation, and necessary fleet. The fare can be made in cash or by contactless smart card called Bilhete Único. The company also manages the bus lanes and bus terminals in the city.
