Abstract
One of the most important issues for enhancing environmental quality, especially
in the urban environment, is developing accessibility versus mobility. With
regard to this, we calculated the accessibility indicator by a zonal opportunity
gravity model (employed person) for 38 local government areas (zones) with
GIS tools, and, in addition, the changes in accessibility measured during 1991–
2001. In addition, the relationship between the accessibility index and six sub
socio-eco-physical factors was calculated by multiple regressing. The result
yielded from a map of accessibility changes shows that two scenarios had taken
place simultaneously. One is a high positive change of accessibility value both in
the central core, mostly strap pattern (concentration) and sub-urban areas
(decentralization), the other is the low positive or negative change of
accessibility value in the middle rings of Sydney. The results achieved by
calculating the relationship between the accessibility index and the socioeconomic
variables show that zones that have low car usage to work have high
accessibility value. In contrast, zones with low weekly income families, far from
the city center, with a high percentage of car usage to work have a low
accessibility value.
Keywords: accessibility, Local Government boundaries, urban environment,
sustainability.
