Companhia de Engenharia de Tráfego (CET) is the municipal agency responsible for traffic engineering, control, and regulation in São Paulo, Brazil, operating under the aegis of the Prefeitura de São Paulo. The agency administers arterial management, signalization, and road safety programs across the São Paulo State capital, coordinating with state and federal bodies such as the Governo do Estado de São Paulo, Departamento Estadual de Trânsito de São Paulo, and agencies linked to the Ministry of Infrastructure. CET's remit intersects with urban planning, transportation policy, and public safety institutions including the Secretaria Municipal de Mobilidade e Transportes, Guarda Civil Metropolitana, and Polícia Militar do Estado de São Paulo.
CET was created in 1968 during a period of rapid modernization in São Paulo that saw investments from entities such as the Banco Nacional de Desenvolvimento Econômico e Social, coordination with the Departamento Nacional de Estradas de Rodagem, and influence from urban planners trained at institutions like the Universidade de São Paulo and Universidade Estadual de Campinas. Early projects aligned with infrastructure programs modeled after international examples such as the Interstate Highway System and urban traffic solutions observed in Paris, London, New York City, Tokyo, and São Francisco. Over decades CET adapted to policy shifts influenced by actors including the Prefeito de São Paulo offices of figures associated with the Partido da Social Democracia Brasileira, the Partido dos Trabalhadores, and municipal administrations collaborating with international bodies such as the Banco Mundial and the Inter-American Development Bank.
CET's governance structure reports to the Prefeitura de São Paulo and interfaces with municipal secretariats like the Secretaria Municipal de Urbanismo e Licenciamento, Secretaria Municipal da Saúde (São Paulo), and Secretaria Municipal de Educação (São Paulo) for cross-cutting programs. The leadership cadre comprises appointed executives analogous to heads in institutions such as the Companhia Paulista de Trens Metropolitanos, SPTrans, and the CETE (Centro de Estudos de Tráfego). Oversight and auditing can involve bodies like the Tribunal de Contas do Município de São Paulo, Ministério Público do Estado de São Paulo, and legislative scrutiny by the Câmara Municipal de São Paulo. CET coordinates with metropolitan consortia exemplified by entities linked to the Região Metropolitana de São Paulo and agencies engaged in São Paulo's international relations with cities such as Bogotá, Buenos Aires, Lima, Mexico City, and Lisbon.
CET's primary functions include traffic engineering, signal timing, curb management, parking regulation, and implementation of road safety measures across arterials, avenues, and expressways such as the Avenida Paulista, Marginal Tietê, Marginal Pinheiros, and feeder corridors that connect to highways like the Rodovia Anhanguera and Rodovia dos Bandeirantes. It issues permits and coordinates works affecting mobility, interacting with public transport operators such as SPTrans, ViaQuatro, CPTM, and private concessionaires on projects tied to Linha 4–Amarela (Metrô de São Paulo), Linha 6–Laranja (Metrô de São Paulo), and bus rapid transit corridors inspired by models from Curitiba and TransMilenio. CET enforces traffic rules in collaboration with Departamento Estadual de Trânsito de São Paulo (DETRAN-SP), implements safety campaigns in partnership with organizations like Associação Brasileira de Engenharia de Tráfego, and supports emergency responses coordinated with Corpo de Bombeiros do Estado de São Paulo and SAMU (Serviço de Atendimento Móvel de Urgência).
Operationally, CET manages signal networks, incident response, lane control, and special-event traffic plans for venues such as the Estádio do Morumbi, Allianz Parque, Autódromo José Carlos Pace (Interlagos), and cultural institutions like the Theatro Municipal (São Paulo). Traffic operations draw on collaborations with research centers such as the Instituto de Pesquisas Tecnológicas, academic partners at the Universidade de São Paulo (USP), Universidade Federal de São Carlos, and consultancy firms that have worked on projects with the Banco Interamericano de Desenvolvimento. Tactical responses coordinate with the Polícia Militar do Estado de São Paulo, Guarda Civil Metropolitana, and municipal secretariats to manage protests, parades, and sporting events involving organizations like Futebol Clube Corinthians Paulista, São Paulo FC, and Sociedade Esportiva Palmeiras.
CET employs technologies including adaptive signal controllers, closed-circuit television systems, traffic sensors, and centralized traffic control centers inspired by systems used in London and New York City. Infrastructure responsibilities cover road markings, signage conforming to standards from the Departamento Nacional de Infraestrutura de Transportes, and integration with intelligent transport systems promoted by international forums such as the International Transport Forum and International Association of Public Transport (UITP). CET has piloted initiatives in cooperation with companies and institutions like Siemens, IBM, Embratel, and research programs at the Instituto Tecnológico de Aeronáutica for data analytics, mobility apps linked to SPTrans Bilhete Único systems, and trials involving electric vehicle charging networks tied to policies from the Ministério do Meio Ambiente (Brasil).
Public-facing services include driver information, education campaigns with partners such as Instituto Ayrton Senna, school safety programs coordinated with the Secretaria Municipal de Educação (São Paulo), and accessibility initiatives aligning with the Conselho Municipal de Direitos da Pessoa com Deficiência. CET runs awareness projects alongside civil society groups like Associação Nacional de Transportes Públicos and media campaigns using outlets such as Folha de S.Paulo, O Estado de S. Paulo, and broadcasters including Rede Globo and Band. Community engagement has involved collaborations with neighborhood associations in districts like Sé (distrito de São Paulo), Pinheiros, Jardins, and Mooca to address localized circulation, loading zones, and pedestrianization trials influenced by cases in Barcelona and Amsterdam.
CET has faced scrutiny from the Ministério Público do Estado de São Paulo, investigative reporting in publications like Veja and CartaCapital, and campaigns by civic groups such as Movimento Passe Livre for decisions on bus lanes, parking enforcement, and congestion management. Criticisms have involved disputes over metrics used in corridor performance, the impact of schemes on informal vendors in Mercado Municipal de São Paulo, legal challenges in the Tribunal de Justiça do Estado de São Paulo, and debates over privatization and public–private partnerships related to projects with firms tied to the Programa de Parcerias de Investimentos (PPI). High-profile incidents have prompted parliamentary inquiries in the Câmara Municipal de São Paulo and audits by the Tribunal de Contas do Município de São Paulo.
