Traffic Signal Operations
Length: Approximately 8 hours.
Description
This course gives the student an overview of the terms associated with signal timing; discusses the concepts of cycle length, split, offset, midblock friction, phase sequences, the signal timing process, and signal timing optimization; and looks at the types of actuated controllers, passage time, extension, and the coordination of actuated and pretimed controllers. It also discusses the development of timing plans, explores types of signal control (first generation control and advanced techniques, including Rhodes, RT-TRACS, SCAT, and SCOOT) and investigates the relationship of signal timing to ITS: regional and system/design considerations.
Objectives
Upon completion of the course, participants will be able to:
- Discuss the fundamental concepts underlying traffic control signal timing
- Identify the different types of traffic control signals and their operating characteristics
- Define the terms used to evaluate the effectiveness of traffic signal control
- List the steps involved in developing timing plans
- Recognize the role of traffic signal control systems within the broader context of ITS
