Traffic Engineering

Abstract

The transportation system is often referred to as the nation ' s

" lifeblood circulation system." Our complex system of roads and highways, railroads, airports and airlines, waterways, and urban transit systems provides for the movement of people and goods within and between our densest urban cities and the most remote outposts of the nation. Without the ability to tavel and to transpot goods, society must be stmctured around small self-suicient communities, each of which produces food and mateial for all of its needs locally and disposes of its wastes in a similar manner. The benefits of economic specialization and mass production ae possible only where transportation exists

to move needed mateials of production to centralized loca- tions, and inished products to widely dispersed consumers.
