i. Physical and Spatial Dimension: Built form, physical extent and location.• Development intensity - higher floor areas, higher coverage;ii.iii.Quantitative Dimension: Population, residential density, land and floor area, landuse activity, facilities/ services, open space and other; andQualitative Dimension: Urban management, safety and security, public openspace, basic needs/ health, social support/ community, access/ transportation,and employment.• Located at most connected and accessible points within the urban system;• Form economic and employment centres (include business, commercial and retailactivities);• Have logistics and freight transport support and access;The focus of the urban morphological model is on the spatial and quantitative dimensions,as these are incorporated into the GIS system.• Mixed use activities - vertical and horizontal mixed use, diversity of activities thatreinforce one another and form a mixed economy;• Public transport supported/ driven (reduced car dependency, environmentaland health benefits, even reducing parking requirements);• Higher residential densities and mix of residential types;• Streets have multiple functions (beyond mere vehicle conduits);• Walkability, with supporting public space environment;• Predicated on a street grid system, most efficient;Figure A.2.4: Modelling key components of Urban Morphological Types.The development principles that underlie the establishment of the urban morphologicalelements include:• Concentration/ agglomeration of activities - economies of scale and efficiency;• Sustainability in terms of environmental respect, social needs and economicviability;• Provision of supporting public facilities and social services; and• Supporting engineering services (capital web).The consolidation of the development principles forms a baseline to establish the potentialphysical and spatial extent, and associated quantitative dimension of the morphologicalelements. Collectively these identify the typical performance of an element.
