The MRA forms an important platform in this regard with voluntary municipal commitments to a joint spatial vision. The regional transport authority offers another venue for inter-municipal co-operation. These metropolitan governance structures are discussed in Chapter 3. One of the few organisations in place today that can provide such co-ordination is the Austrian Conference on Spatial Planning (Osterreichische Raumordungskonferenz, OROK) that assembles representatives from all levels of government to discuss spatial policies. Further, as it is located at the centre of government (within the Office of the Chancellor), it may also be able to carry out the necessary cross-sectoral policy co-ordination between different branches of the national government. Its decision-making body is chaired by the Federal Chancellor and its members include all federal ministers, the heads of all federated states and representatives of associations of local governments.
