WHAT THIS IS ABOUT
A brief introduction to the history of traffic signals will illustrate the evolution of intersection traffic control through the years. The process of justifying the installation of a traffic signal will be discussed, exemplified and supported by a thorough explanation of the current MUTCD Warrant analysis. Additional information on Part 4 of the MUTCD will be presented, focusing on the design and positioning of signal indications and illustrated with examples and tables. MUTCD provisions, such as the optional use of “flashing yellow arrow” for permissive only or protected-permissive modes will be discussed. Guidance to design pedestrian control features will also be provided. An afternoon session on traffic signal terminology will include the definition of phase, a detailed explanation of the standard NEMA ring-and-barrier diagrams, and the treatment of left-turn phases being followed by a presentation on operational characteristics of traffic signals.
