Traffic Signal Lab
DEPARTMENT OF TRANSPORTATION STUDIES
Traffic Signal Cabinet
The Traffic Signal Lab is a state-of-the-art laboratory dedicated to education, training, and research for traffic signal operations. The lab includes a TS-2 Type 2 traffic signal cabinet, a NEMA cabinet display, several ATC NEMA traffic signal controllers, and other traffic signal related equipment. The Traffic Signal Lab will be used for the course TMGT 865, and it will familiarize students with the design and interpretation of traffic signal plans, the components of a traffic signal system, and advanced traffic signal controls.
Traffic Signal Lab setting
This lab provides us the capability of conducting full intersection signal control demonstrations and tests. The unique environment of the Traffic Signal Lab exposes students to the complexities of setting up and maintaining traffic signal controllers, conflict monitors, load switches, detection and communication systems on traffic signal cabinets; and as a result, the students will have hands-on experience working with traffic signal related equipment. Having those experiences will provide the students better opportunities to apply for the jobs in all areas of traffic operations. This lab can be used for educating and training of signal technicians and traffic engineers in the public and private sectors.

The Traffic Signal Lab has been also established to support research in the area of traffic operations. The lab employs Controller Interface Device (CID) units linking the actual traffic signal controllers with traffic micro-simulation software (hardware in-the-loop simulation, HILS). This system provides the capability of designing and testing optimized signal control strategies in a virtual environment. It allows for the realistic evaluation of controller operations and traffic control strategies without disturbing real traffic flow. It is an essential research asset that will enhance the research productivity and funding opportunities for TSU.
