Traffic Signal Operations

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.
