All lines operated by Metro will operate normally this Sunday (21st), day of the National High School Examination (Enem). As reported by the Metrô, there are no scheduled tests or maintenance activities on the roads that interfere with the operating hours on the weekend. 
The fleets scheduled to circulate on lines 1-Blue, 2-Green, 3-Red and 15-Silver will be similar to those used on other weekends, however, due to Enem, reserve trains will be prepared to go into operation at any time if any increase in demand is observed.
To avoid last-minute surprises, Metrô recommends that everyone, if possible, schedule their trip to the venues in advance and make advance purchases. In case of doubt, passengers may contact the Metro Information Center daily, between 8:00 am and 8:00 pm, by calling 0800-770-7722.
Traffic
The Traffic Engineering Company (CET) will carry out a special traffic operation for this Sunday in Enem, monitoring the main corridors of the city, to ensure safety conditions for pedestrians and fluidity in traffic in the capital of São Paulo.
The CET teams will intensify monitoring, streamlining the removal of interference, inspection in embarkation and disembarkation areas, guidance of pedestrian crossings and the operation of traffic lights.
Avenida Paulista, which is part of the Open Streets Program, will be closed to the public on Sunday morning (21st), until 13:00. The measure aims to facilitate the movement of students who are going to take the Enem tests, with free traffic for buses and vehicles.
For those who want to follow alternatives to the traffic on Avenida Paulista, the tips are:
Direction Paraíso/Consolação: Avenida Bernardino de Campos, Rua Treze de Maio, Rua Cincinato Braga, Rua São Carlos do Pinhal, Rua Antônio Carlos and Rua da Consolação.
Consolação/Paraíso Direction: Alameda Santos, Cubatão Street, Abílio Soares Street, Bernardino de Campos Avenue.
For traffic information, occurrences, complaints, removals and suggestions, call SP156. The service is 24 hours a day.
Buses
SPTrans, the public bus transport system in the city of São Paulo, informed that the fleet scheduled for this Sunday will correspond to 100% of a Sunday.
See the list of lines and schools served here to facilitate the arrival of students to the Enem test sites.
single ticket
On Sundays, those who have a Single Student Ticket (free or half-fare) can use up to four different buses in a two-hour period, paying only one fare. Those who have the Bilhete Único with common credits can use up to four buses in a period of eight hours during Sundays and holidays, paying only one ticket (provided that the last recharge was at least four fares).
In the first two hours, it is possible to use the Single Common Ticket in the integration with Metro or train. For the next six hours, only buses should be used, as long as the total number of trips by bus + subway / train does not exceed four trips, in order to avoid charging a new fare.
