Proceedings of the Second International Conference on the International Society for Terrain-Vehicle Systems

Transportation" results from the synthesis of economic, sociologic, political, environmenta l, and technological factors into a means whereby people and goods can be moved with acceptable levels of safety, comfort, convenience, and cost. In defining what form transportation should take now or in the future, here or abroad, these factors must all be examined to the degree appropriate to each particular problem. The problems that are important to transportation planners are those of policy, research, and development, alternative approaches, and specific engineering developments. A methodology that may be used to structure each of these problem areas in any specific situation is discussed in terms of its philosophy, its logic, and its potential. .. . for several hundred years the great evolutionary hormones of knowledge and technology have been pressing us ... whether we like it or not, into a single coordinated humankind. The scattered and competing pasts are being bound together. Everywhere now we begin to see men and nations beginning the deliberate design of development with a growmg confidence in the choice and creation of their own future. ## John R. Platt, The Step to Man TRANSPORTATION DEVELOPMENT PROBLEMS THE PROBLEMS THAT are facing every country in the world today, engendered by mushrooming economic and population growth, impose an extraordinary burden on those responsible for transportation systems development. Without a seasoned, balanced, planned, and co-ordinated "blueprint" for the future transportation capabilities of a country, that country's future strength and economic well-being will be in jeopardy. This fact is recognized at the highest levels that forge political and technological progress in the United States.
