CEUs: 1.60


This course covers the concepts, practical applications, and operations of isolated traffic signals. The course engages students through hands-on exercises and real-world examples of signal timing and operations. Class exercises and demonstrations are taught in a computer lab. A basic knowledge of EXCEL is needed to complete the exercises.

NOTE: This is an introductory course in a series of courses on traffic signal operations offered by the Technology Transfer Program. It is strongly recommended that students complete this course before taking either Traffic Signal Operations: Coordination for Corridors (TE-10) or Synchro and SimTraffic (TE-13). It is also helpful for students to complete this course before taking Type 170 & 2070 Traffic Signal Controllers (TE-25).

What this class is not:
  • You will not learn how to coordinate signals, this is covered in TE-10.
  • We will not teach you to use Synchro, this is covered in TE-13.
  • You will not learn how to program controllers and equipment - only partial instruction on timing sheets and detector settings, etc., this is covered in TE-25.
  • You will not learn how to design signals, only how to define specifications like detector setbacks, turn lane lengths, etc. Traffic signal design is covered in TE-02 and TE-41.
For other Tech Transfer courses for the above topics beyond this course, please see Traffic Signals.

Topics Include

  • types of traffic signals
  • principles of signal timing
  • timing of fixed and actuated signals
  • pedestrian considerations
  • introduction to signal coordination
  • detector logic
  • gap settings
  • recall and other features
  • signal timing using Excel Spreadsheet (PlanSig)
  • when to change timing settings
  • Synchro input
  • learn to understand Synchro output (PlanSig results will be compared to Synchro output for one of the in-class problems)
  • hands-on problems and filling timing sheets

What You Will Learn

Students learn how to time isolated signalized intersections focusing on how to apply basic principles in real-world situations.

Who Should Attend

The class is for traffic engineers, planners, consultants, and technicians who are new to traffic signal timing. Experienced practitioners who desire a "refresher" course might also benefit from this course.
