Since 2007, the Trinational Agglomeration of Basel has allowed the coordination and implementation of concrete measures across the entire territory of the agglomeration. These measures meet the objective of articulating the preservation of landscapes,, the management of urban development and the implementation of public transport services within the territory of the agglomeration. The project is led by a trinational association Agglo Basel of which all the local authorities making up the agglomeration are members. The overall project is designed to ensure that investments in infrastructure are coordinated and balanced between the three national components of the agglomeration.
