Introducing Large Scale Urban Model to Sydney’s Metropolitan Planning
Year: 2011

Abstract: By 2036 Sydney’s population is expected to reach six million, an increase of 1.7 million since the 2006 census. To achieve a liveable and attractive city, Sydney Metropolitan Strategy 2006 presents detailed plans for Sydney’s future and allocates a precise number of additional residents to each local government area using the planning tool named METRIX. As the pattern of human settlement directly impacts on the issues of transport, environment and economy, METRIX, however, is limited and incapable of accounting for the external restrictions to population distribution. There is a further question of the extent to which this strategy will be implemented, since there is no appropriate planning system currently in place. Therefore, a planning model capable of evaluating the suitable locations to accommodate the growing population and providing alternative options for Sydney’s future, as well as facilitating the cooperation among different departments, is in urgent need to produce a flexible and responsive metropolitan strategy.To resolve these practical issues, this paper turns to academic research on the concept of planning support system. By reviewing the presently popular urban models, the author argues that most previous efforts are forced on modelling techniques, and these methods cannot simulate the correct process of urban growth. This also makes the relative research more successful in the laboratory than that in practice. The proposed model in this paper, instead, takes the notion of “Enterprise Resource Planning” to pull the endeavour back to constructing a collaborative population distribution model. The model first examines the macro level influences in people’s choice of living through spatial regression, and then generates suitability score using factor analysis to reflect the micro fitness. Afterwards, the additional population is distributed along the logistic curve with a yearly basis. The whole model is constructed in ModelBuilder of ArcGIS 10 employing the data of 55158 polygons, where the smallest area of residential block is 154 m2.
