Around the world, particularly in North America and Australia, urban sprawl combined with low density
suburban development has caused serious accessibility and mobility problems, especially for those who do not own a
motor vehicle or have access to public transportation services. Sustainable urban and transportation development is seen
crucial in solving transportation disadvantage problems in urban settlements. However, current urban and transportation
models have not been adequately addressed unsustainable urban transportation problems that transportation disadvantaged
groups overwhelmingly encounter, and the negative impacts on the disadvantaged have not been effectively considered.
Transportation disadvantaged is a multi-dimensional problem that combines demographic, spatial and transportation
service dimensions. Nevertheless, most transportation models focusing on transportation disadvantage only employ
demographic and transportation service dimensions and do not take spatial dimension into account. This paper aims to
investigate the link between sustainable urban and transportation development and spatial dimension of the transportation
disadvantage problem. The paper, for that purpose, provides a thorough review of the literature and identifies a set of
urban, development and policy characteristics to define spatial dimension of the transportation disadvantage problem.
This paper presents an overview of these urban, development and policy characteristics that have significant relationships
with sustainable urban and transportation development and travel inability, which are also useful in determining
transportation disadvantaged populations.
