5 What is Engineering? en·gi·neer·ing (n.) -The application of scientific and mathematical principles to practical ends such as the design, manufacture, and operation of efficient and economical structures, machines, processes, and systems. Chemical EngineeringChemical Engineering Mechanical & Industrial EngineeringMechanical & Industrial Engineering Electrical & Computer EngineeringElectrical & Computer Engineering Civil & Environmental EngineeringCivil & Environmental Engineering

6 What is Transportation? The safe and efficient movement of people and goods! the branch of engineering which applies technology, science, and human factors to the planning, design, operations and management of roads, streets, bikeways, highways, their networks, terminals, and abutting lands The objective is to provide for the safe, rapid, comfortable, efficient, convenient, and environmentally compatible movement of people, goods, and services.
