1. What is a system? A group of separate parts that work together to perform a specific function.

2. 1.Take a minute to think about the term Intelligent Transportation System and then name a few of the goals that an Intelligent Transportation System might be designed to achieve.  Improve safety  Improve security  Improve transportation times  Improve fuel consumption

3. 2.Think about how an Intelligent Transportation System might improve your life.

4. 3.Students, working in pairs, will list some of the subsystems that might be part of an Intelligent Transportation System.

5. 1.Systems thinking involves considering how every part relates to others. a.System – A group of interacting, interrelated, or interdependent elements or parts that function as a whole to accomplish a goal. b.Resources – Things needed to get a job done. c.Requirements – The parameters or limitations placed on the development of a product or system.
