The movement of people and goods throughout the world is primarily dependent upon
a transportation network consisting of roadways. Most, if not all, business economies,
personal economies, and public economies are the result of this transportation system.
Considering the high initial and annual costs of roadways, and since each roadway
serves many users, the only prudent owner of roadways is the public sector. Thus it is
the discipline of civil engineering that manages the vast network of roadways.
