Students will become familiar with components of a traffic signal system and with appropriate traffic signal maintenance procedures. The Center for Transportation Research Traffic Signal Laboratory is a unique learning environment that allows the user to be exposed to the complexities involved with setting up and maintaining traffic signal controllers, conflict monitors, load switches, detection and communication systems on both NEMA TS-1 and TS-2 cabinets. Installation and maintenance guidelines of traffic signal supports and indications will also be provided. General information on the design and interpretation of traffic signal plans and a checklist for preventive and responsive maintenance will also be discussed. Appropriate information regarding liability and negligence will be presented in addition to guidelines to reduce exposure to lawsuits.


Since 2010, the Traffic Signal Academy has provided services to over 1,000 participants in 6 different courses. Federal, state, county and city agencies plus consultant firms have attended our classes.
