AMT, the Autoridade da Mobilidade e dos Transportes, is Portugal’s national regulator for mobility and transport. Based in Lisbon, it was created under Decree-Law No. 78/2014 of 14 May and operates as an independent public authority with a broad mandate across land, river, rail and maritime transport, as well as the infrastructure that supports them.
Its mission is to regulate and supervise the sector, combining oversight of operators with monitoring of infrastructure and market conditions. In practice, that means AMT issues opinions, carries out supervisory actions, publishes statistical reports and monitors compliance in areas ranging from rail investment execution to port market developments and road freight transport requirements. The authority also manages a user portal, a complaints system and an observatory for mobility and transport, indicating a role that goes beyond pure regulation into consumer protection and market transparency.
Recent activity on its website shows a steady flow of analysis and supervision. In 2026, AMT published a statistical report on the implementation of Covid-19-related support measures, monitored delays in railway infrastructure investment, released monthly port market updates and launched a new centralized complaints management system using artificial intelligence. It also approved a new regulatory model for railway infrastructure access charges. These outputs show an institution focused on both enforcement and sector monitoring.
AMT’s scope is national, but its work is relevant to wider European discussions on transport regulation, infrastructure governance and public service oversight. Its headquarters are in Palácio Coimbra, on Rua de Santa Apolónia in Lisbon, placing it at the center of Portugal’s transport administration.
