Traffic Signal Academy

Traffic signal operations play an important role in the safe and efficient movement of people, goods, and vehicles through our roadway systems.

According to the 2012 National Traffic Signal Report Card, the overall quality of traffic signal operations in the US is not satisfactory. In particular, the report stresses the need for routine signal timing updates to keep pace with changes in population growth and traffic patterns.

Investing in traffic signal training, from design to operations to maintenance, demonstrates a robust commitment to continuous improvement in the nation's transportation system

The academy offers a comprehensive discussion on standards, warrants, installation and maintenance guidelines, and strategies to minimize the adverse effects of liability issues. Take all three courses and learn: Timing, Detection & Advanced Operations; Installation & Maintenance; and Performance Measures & Controller Programming. The courses include course materials and light refreshments. Attendees are responsible for meals.  Restaurants and fast-food chains are available close to the UAH campus.


Timing, Detection
& Advanced Operations

September 30, 2020

Discusses traffic signal terminology, traffic signal timing objectives, benefits, characteristics and strategies for coordinated and non-coordinated intersections. Simulation examples will illustrate the functionality of several controller parameters related to current guidelines on detection system design for low and high speed approaches. Volume Density, Traffic Signal Priority Control, Traffic Responsive Control, Adaptive Traffic Signal Control and Preemption will be discussed.


& Maintenance

October 1, 2020

Presents components of a traffic signal system and appropriate traffic signal installation and maintenance procedures for traffic signal controllers, conflict monitors, load switches, detection and communication systems on NEMA 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 agency exposure to lawsuits.


Performance Measures
& Controller Programming

October 2, 2020

Discusses ATSPMs and presents guidelines to identify appropriate operational objectives based on typical observed conditions. Presents available mitigating strategies that can have an appreciable effect on overall system performance. Students will also experiment with controller parameters on a realistic simulation environment and will be presented with information on how to navigate traffic signal controller menus, including programming instructions and interactive examples on timing parameters, detection, coordination and advanced functions.
