Modelling Urban Sustainability: The PROPOLIS Experience Michael Wegener SOLUTIONS 2004 Symposium Cambridge, 15 December 2004
PROPOLIS (2000-2004) PROPOLIS (Planning and Research of Policies for Land Use and Transport for Increasing Urban Sustainability) was a project of the Key Action “City of the Tomorrow” of the 5th RTD Framework of the European Commission. Objectives - to research, develop and test integrated land use and transport policy assessment tools and methodologies - to define sustainableurban strategies and to demon-strate their long-term effects

Microdatabase For the synthetic microdatabase zonal data are allocated to raster cells. Two steps are performed: (1) Conversion of polygons to raster cells The polygons of a land-use map are converted to raster cells and each raster cell is assigned a land-use category. Land-use categories Residential high-density Residential low density Industrial Open Space

Sustainability In PROPOLIS, sustainable development consists of three interconnected components: - ecological or environmental sustainability - social or human sustainability - economic efficiency
