Module 4: Lesson 1 - Traffic Signal Design

This learning module, from the National Center for Autonomous Technologies (NCAT), provides a lesson on traffic signal design for middle school students. The lesson introduces students to Intelligent Transportation System (ITS) concepts whereby the transportation infrastructure of roadway sensors, signals, and communication networks, in combination with vehicles, can control traffic signals to minimize wait times and maximize traffic flow efficiency. Learning outcomes include the following: 

• Through discussion, data collection, and various activities, students will recognize the need for traffic signals.
• Students will use the engineering process to effectively evaluate a signalized intersection.
• Students will identify specific ITS technologies that can be used to improve traffic flow and reduce vehicle delay.
