This report examines demographic, economic and market trends that affect travel demand(the amount and type of travel people will choose), and their implications for transport
planning. Motorized mobility grew tremendously during the Twentieth Century due to
favorable demographic and economic conditions. But many factors that caused this
growth, such as declining vehicle operating costs and increased vehicle travel speeds, are
unlikely to continue............... : Click here
Global economic, environmental and political issues are pushing car manufacturers to considerelectric power systems as an alternative to the current spark ignition engine. In this article, we analyse the power and energy requirements of a modern car and conclude that a viable electric car could be operated with a 50 kW polymer electrolyte fuel cell (PEFC) stack to provide power for cruising and climbing, coupled in parallel with a 30 kW supercapacitor or battery bank to supply additional short term burst power during acceleration.......... : Click here
Hybrid vehicles may provide some limited efficiencies, but tend to initially cost more to buywhich negates their perceived advantage. Various hybrid types have been produced or are under
investigation with the latest trend being toward plug-in varieties that seem to combine the benefits
of electric cars with an engine in reserve. Electric vehicles have a long history of development but
suffered from range and safety problems, which have only recently been addressed with new
nanotechnologies. Other options, like compressed air cars and hydrogen concepts, seem to have a way to go for acceptance by the vehicle industry, consumers and driving commentators.............: Click here
