This two-hour webinar is designed to enable the participants to obtain a basic understanding of the fundamental concepts for traffic signal timing and coordination of signalized intersections. This will include isolated intersections and those that are in a coordinated signal system.


  • Understanding of basic timing parameters
  • Understanding of isolated or free operation vs. coordinated operation
  • Understanding of coordination timing parameters (Cycle, Offset, Split, Sequence)
  • Identify the different types of traffic control signals and their operating characteristics
  • Learn Leading Pedestrian Interval (LPI) and how to successfully implement LPIs to improve pedestrian safety at signalized intersections


Time Section Topic
8 Minutes Introduction Participant Introductions; Course Introduction; Timing Goals; Review of Timing Goals; Glossary of Terms
