Transport in São Paulo plays a key role in the date-to-day life of the people of São Paulo. Although lacking in strong infrastructure, various methods of public transport are offered in the city, including a complex bus system run by SPTrans, and various subway and railway lines. A contactless smartcard is used for fare collection for the buses, subway, and railway systems. São Paulo also has three airports.
Over 16,000 buses form the bulk of public transport in São Paulo; they include about 290 trolley buses. Except for a small network overseen by the EMTU, all bus lines are operated by concessionaires under the supervision of SPTrans, a municipal company responsible for the planning and management of public transport. Some of the SPTrans buses are painted in white, while others are painted with region-specific colors. Up until recently, informal transport vans (dab vans) had a large presence in the city, but the vast majority of such vans are now registered with the city council, legalized, and operating under the same color scheme used as the main system. To increase efficiency in the city, São Paulo is implementing a bus rapid transit system called the Expresso Tiradentes. There is also a fast-lane bus system, which are placed on large avenues and connected with the underground or suburban train stations.
The São Paulo Metro has 74.3 km of underground railway systems (34.6 km fully underground), with 5 lines in operation and 64 stations, while the railway system consists of 260.7 km from the Companhia Paulista de Trens Metropolitanos (CPTM) railways. Both CPTM and the underground railway lines carry some 5.2 million people on an average weekday, and a few new underground lines to be constructed are expected to add another million people to the system within the next five years. The projects expected to expand São Paulo's urban railway system from the current 322.2 km to more than 500 km on the next 10 years.
