The transportation system is a basic component of any areas physical, economic, and social structure. Not only does the design and performance of the transportation system provide opportunities for mobility; but over the long term, it influences patterns of growth and the level of economic activity through the accessibility it provides the land. What is Transportation Engineering? The field of Transportation Engineering focuses on the planning, design, construction, and management of transportation systems. These systems consist of the facilities, vehicles, control mechanisms, and the policies that combine to permit the efficient conveyance of people and goods. Designs highway systems (layout, routing), pavement material, airport runways, and rapid transit projects. Also involved in computer control of traffic signals. Transportation Engineering What is Transportation Engineering? It contains the planning, design, construction, maintenance, and operation of air, highway, and urban transportation, as well as pipeline facilities for water
