A sustainable planning strategy is globally important for metropolitan areas. Sustainable planning addresses the development of strategies to reduce the use of resources, increase economic efficiency and improve integration of social aspects (e.g. pedestrian friendly environments, well balanced public and private transport modes, efficient street networks; land use, movement economy,access for all to jobs, retail, services, healthcare, culture, and leisure). In order to reduce urban sprawl, numerous authors recommend going back to the concept of compact cities. However, policies favoring the compact city concept turned out to be less efficient than expected.
Hence, instead of rejecting urban sprawl it seems more reasonable to find solutions better managing the dynamic aspects of cities, in order to reduce traffic costs and pollution, and to avoid undermining natural and agricultural resources. Frankhauser (2004) first proposed reflections onto what extend urban planning concepts referring to fractal geometry could be of interest for reducing negative impacts of urban sprawl.
This paper addresses the further development of Frankhauser´s theoretical model, extending it to be a holistic, comprehensive system. The idea of an "urban" hierarchy (street network, green areas, building blocks, building heights, and urban centres), generated as a multi-scale urban planning model for developing scenarios (regional, urban, architectural scale - 2D & 3D) for metropolitan areas, allows the implementation of highly efficient, functional and sustainable transport networks, masterplans and mass models.
