About this site

The São Paulo State Transportation Regulatory Agency (ARTESP) is a government agency responsible for the regulation, oversight, and monitoring of public transportation services delegated by the State of São Paulo. Its mission is to ensure that these services are delivered with quality, safety, efficiency, and sustainability, contributing to the social and economic development of the state.

In 2024, ARTESP significantly expanded its responsibilities by assuming oversight of services previously managed by the Metropolitan Urban Transport Company (EMTU). EMTU was responsible for managing intermunicipal public transportation in the metropolitan regions of São Paulo, Campinas, Baixada Santista, Vale do Paraíba and North Coast, and Sorocaba. This expansion brought metropolitan bus services, light rail systems (VLT), and other metropolitan transit modes under ARTESP's regulatory scope.

ARTESP also assumed responsibility for regulating the state's rail concessions, including both passenger and freight rail services operated under public-private partnerships. This move further strengthens the agency’s strategic role in the planning and oversight of São Paulo’s transport infrastructure.

Today, ARTESP regulates over 11,000 kilometers of concessioned highways, hundreds of metropolitan bus lines, light rail networks, ferry crossings, charter transport services, and the transport of specialized cargo. The agency operates with transparency and public accountability, making updated and accessible information available through this open data portal.
