The Porto Metropolitan Area (Área Metropolitana do Porto, AMP) is a framework of cooperation
between 17 municipalities and several districts. This metropolitan area has a specific, inter-municipal
model of urban governance. In our research, we found that cooperation is significant mainly in sectors
where the central legislature has essentially made this mandatory, by designing the AMP and defining
its powers. In addition to AMP, only partial cooperation has been established in the field of waste
management, and in the field of human public services and in the performance of public authority, there
is essentially a set of autonomous organisational solutions. However, despite all this fragmentation,
the above system ensures the satisfactory functioning of the metropolitan agglomeration. This also
underlines the importance of transport management in urban areas, since this functioning system is
based on an integrated and intermodal transport system
