REGIONAL IDENTITY: Identity is another characteristic that strengthen the relations within polycentric structures. In this regards, it is important that PUR could be considered as a single urban region in terms of its identity. 4. GOVERNANCE: The governance of polycentric structures is one of the most complex issues, since it deals with multi-level of actors in different levels and competences. One argument for planning at the scale of a PUR is that the governance arrangements provide the region with greater organisational capacity. PUR promotes co-operating of local authorities through voluntary arrangements.Introduction Theoretical Framework Historical Review of Planning in TMR Analysis the Urban Structure of TMR Next Step…

  37. 37. Analytical DimensionThe analytical dimension uses the concept of polycentricity to explain or analysis an existing or emerging polycentric system.This part of the research investigate the urban condition of the TMR in four aspects:• Morphology,• Functional relationship,• Regional identity,• Governance.5. How the population and activities distributed over the TMR territory?6. What is the level of functional interaction and interdependence between various centres in the TMR?7. Could the TMR be considered as a single urban region in terms of identity?8. How the existing governance of the TMR can promote the PUR?
