It is clear from the passage that transport requirements in the industrial countries ----.

Transport represents 22 per cent of total energy
consumption in industrialized countries, mainly in the
form of automobiles. Although this is the fastest
growth sector in such countries, the rate of increase
in road transport energy demand has slowed in most
developed countries since the late 1960s. This has
reflected both improved vehicle efficiency and a
slowing down in the level of acquisition of
automobiles by households. These developments
have encouraged hopes that saturation levels may
operate at lower levels than sometimes projected. In
developing countries, transport represents 14 per
cent of total energy consumption but the number of
automobiles is approximately 20/1000 people,
compared to 600/1000 people industrialized
countries. In attention to strictly technical
improvements that can be made to automobiles and
trucks, there is another important area of action
which could help in the solution of the problems,
namely, system operation. In this category, there is a
variety of actions that could be performed more
efficiently such as transporting passengers and
freight by other means, such as bus and rail that
would result in lower energy consumption and
therefore, lower emissions.
