Prelude to Chapters 3 through 5
Chapters 3 through 5 introduce you to the physical portion of the built environment. The broadest categories are termed infrastructure sectors, such as transportation, structural, or environmental. Some sectors are further broken down into subsectors; for example, the transportation sector includes aviation and mass transit. We will also introduce various components, the most fundamental “building blocks” of the sectors. Examples of mass transit components include roadways (with sub-components of pavement, curbs, etc.), buses, rail lines, and trains. Knowledge of these sectors, subsectors, and components is necessary to understand topics presented throughout the remainder of this textbook. In addition to being able to identify components, you will also begin to understand the interrelationships between components, sectors, society, and the environment.
