The article attempts to identify the shortcomings of the present methods used in Japan for comparing the energy efficiency of various modes of transport. Some new methods of analysis are also introduced. It is hoped that by quantifying factors previously largely ignored (e.g. Quality, mobility, speed and frequency) these new energy efficiency equations will allow the planning of transport systems suited to the needs of large cities, suburbs and rural districts. They also challenge the belief that rail transport is more efficient under all circumstances than road transport. Optimizing the energy efficiency of transportation is of importance in Japan where presently it accounts for about 17% of energy consumption. (TRRL)
