Member authorities (PTAs) in the HVV association
On amendment of the basic legal framework (Regionalization) in 1996 the Bundesländer or Regional German States assumed total responsibility for the organization and funding of local public transport in their areas. Regional states such as Schleswig-Holstein and Niedersachsen (Lower Saxony) subsequently undertook a split of the various obligations. The counties were assigned the task of organizing and funding the bus service offer. The regional states themselves remained responsible in the local rail sector.
