While much research has shown that vehicle demand is related to urban spatial structure, very little research has investigated the spatial patterns of private vehicle fuel efficiency (VFE) and its association with socio-spatial circumstances in urban areas. This study has combined State-level motor vehicle registration datasets with standard vehicle efficiency measures that permit a comprehensive understanding of spatial variation of VFE in urban areas. A spatial-based technique was applied to explore intra-urban patterns in socio-spatial conditions of private vehicle efficiency in Brisbane and Sydney. In both cities, the VFE of the private vehicle fleet tends to be lower in outer suburbs than in middle and inner suburbs. The analysis further shows that by linking the standard vehicle efficiency measures to the entire urban fleet datasets the VFE outcome showed a moderate relationship to socio-spatial variables in both cities. The built environment and household economic status are more transferable factors that relate to the VFE across different urban contexts. Outcomes from this research are of relevance to policy makers charged with identifying highly oil-vulnerable communities and designing intervention strategies to improve household vehicle efficiency.

The Brisbane ferry network has grown significantly over the past fourteen years and is now a key commuter and tourist transport mode that in 2008 carried 6.28 million passengers, servicing 23 locations throughout the city. Two new ferry terminals will be built over coming years with private land developers contributing partial ...

Socioeconomic status (SES) and spatial location partly determine differential accessibility. Spatial variation of low-SES groups across cities and the travel patterns of these groups have been mostly ignored by strategic transport models, which have been concerned more with traffic volumes on the road network and peak hour travel.

However this apparent similarity belies some fundamental differences between the two regions in terms of context and the approach to regulating development. This paper describes some of these key differences, but focuses on two research questions: 1) do these differences affect the built environment; and 2) if so, how does the built form differ? There has been considerable research on how to best measure urban form, particularly as it relates to measuring urban sprawl (Schwarz 2010; Clifton et al. 2008). Some of the key questions identified by this research include: what are the best variables to use?; what scale should be used?; and what time period to use? We will assimilate this research in order to develop a methodology for measuring urban form and apply it to both case study regions. There are several potential outcomes from this ...

The burgeoning conurbation of South East Queensland (SEQ) is an example. Recent growth management policies and plans (e.g. South East Queensland Regional Plan and local authority growth management strategies) have sought to curtail urban sprawl through urban footprints, growth management boundaries, urban consolidation, and other measures. The ‘density imperative’ presented by these collective urban policies affects the sourcing, provision and management of open space in inner-city locales in SEQ which may soon run out of land for parks and urban greenspace. This paper presents results from recent research into the environmental equity dimensions of providing urban greenspace in SEQ. Critiquing the long-entrenched parks-standards approach, the paper offers a ‘needs-based’ alternative, and considers its utility for SEQ and other fast-growing Australian urban areas. Questioning orthodox planning perspectives about who lives in higher density areas, we argue that local and state governments should look towards a variety of new types of green and open space to meet the needs of existing and future residents living in denser built environments.
