How will we get there? New approaches to analyzing low-Socio-Economic Status Household access to destinations in Australian cities

摘要

Access to essential goods and services is increasingly recognized as a key factorinfluencing household socio-economic disadvantage within cities. Socio-economicstatus and spatial location partly determine differential accessibility. Spatial variationof these low-SES groups across cities, and their travel patterns, are mostly ignored bystrategic transport models, which are concerned more with traffic volumes on the roadnetwork and peak hour travel. This paper expands on a method using cluster analysistechniques to identify low-SES groups on the Gold Coast (Australia) from a largeregional household travel survey. This allows for the identification of the actual travelbehavior of low-SES groups. Using this information, the paper advances a neworigin/destination-based land use and transport accessibility model. The model usesthe output from the cluster analysis, in conjunction with 2006 Australian census data,to highlight accessibility to goods and service needs for a set of low-SES groups onthe Gold Coast. The method being developed provides unique opportunities forresearch into spatial disadvantage and accessibility in Australian cities. Theconceptualization of the transport network with outputs provided at the censuscollection district level (approximately 200 households) ensures that the model can berun concurrently with conventional transport models.
