ABSTRACT
This group of papers argues convincingly the likely developments in transport over the next 40 years. In spite of minor differences in point of view of the individual authors, a remarkably consistent concensus emerges in which initial growth gives way to a transition to low growth in almost all sectors of transportation. The inevitable progressive replacement of oil-derived fuel with coal or shale-derived fuel, during the period considered, will probably result in a fuel price plateau which will govern the dynamic equilibrium between modes of transport and the economy as a whole. A possible gap in the presentations is a discussion of the function of government in effecting energy savings by legislation. For example, a law which permitted left turn on red at traffic lights could save fuel in urban areas-the USA has already made such a law. Similarly the widespread use of flexi-time in industry would reduce rush hour congestion, again saving fuel on motor cars and permitting better utilization of public service vehicles. The key role of conservation in all modes of transport is emphasized, and in common with other applications of energy conservation principles, it is clear that there is no single solution, but rather an optimization of each transportation system on a case by case basis.
