Lesson focuses on how engineers have developed and improved traffic management over time by engineering and re-engineering the traffic light. Students work in teams to design a new traffic light system to meet the needs of a potential client. They must devise a system or technical enhancement to accommodate a busy bicycle lane and roadway that
intersects a hospital emergency room entrance. As a team they devise their planned improvements, draw a design of the improved traffic signal, develop a written and verbal presentation to the client, present their designs to the class, provide feedback on other team’s designs, and share observations about re-engineering.
8 – 18
- Learn about traffic engineering.
- Learn about engineering design and redesign.
- Learn how engineering can help solve society’s challenges.
- Learn about teamwork and problem solving.
Anticipated Learner Outcomes
As a result of this activity, students should develop an understanding of:
- traffic engineering
- engineering design
Students explore how engineers redesigned or re-engineered the traffic signal over time to enhance its functionality. They work in teams to develop a proposal to a prospective client for a new enhancement to the traffic signal that accommodates both a bicycle lane and the entrance to a hospital emergency entrance for ambulances. They consider patenting options, how the new design might impact costs, and present their ideas to the client (class).
