TE-04 Traffic Signal Operations: Isolated Intersections
Please Note: This is a computer lab.
DescriptionThis 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.
- 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 LearnStudents learn how to time isolated signalized intersections focusing on how to apply basic principles in real-world situations.
Who Should AttendThe 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.
