Most theoretical and empirical research on the subject of urban transport
energy consumption has addressed the role of urban form and urban spatial
structure (primarily population density and degree of centralisation), city
size (population and/or area), the level of economic development, transport
patterns, and transportation infrastructure. Our analysis encompasses a wide
range of socio-economic, spatial, transport and infrastructure indicators, as
well as energy efficiency and energy consumption indicators in a sample of 35
world cities, covering the period from 1960 to 2005. Comparative analysis
indicates there are significant differences regarding the determinants of
urban transport energy consumption, especially between the US and Australian
automobile-dependent cities, on the one hand, and the wealthy Asian
metropolises, on the other. Despite some recent positive trends (a decline in
automobile vehiclekilometres and reduction in urban transport energy
consumption), a large number of cities in the developed world still rely
predominantly on cars, while sustainable modes of urban transport play an
almost negligible role. Due to trends of urbanization, demographic growth and
a rise in living standards, the main focus of attention has shifted to
metropolises in developing countries. In the long run, the urban form itself
is particularly significant, not only because it critically influences
transport demand, but also because of its inertness.
