| This project uses a model (PUP – Projections for Urban Planning) to forecast the location of housing development and population growth on large city fringes. The model couples the land use and housing unit methods of population forecasting in a GIS framework. Work has focused on incorporating spatial relationships, calibration, and visualisation. Three factors are involved: land availability; accessibility to facilities and other stimuli; and adjacency to existing development. These are weighted and combined to determine the probable location of future development. The model has been implemented in Adelaide but its generic structure yields a flexible, interactive forecasting system to assist in urban planning and other fields. |
