Traffic Signals

This PennDOT Traffic Signal Maintenance and Operations self-study was created from a need to understand that the congestion and delays that exist on our streets and roadways can be better managed with a thorough understanding of effective traffic signal operations and maintenance. Well maintained and operated traffic signal control projects are essential to this process. This course will focus on the proper elements of a well maintained and operated traffic signal system. The course is divided into two primary parts: Traffic Signal Operations and Traffic Signal Maintenance.

Learning Outcomes: At the end of this Traffic Signal Operations and Maintenance course, you will be able to:
• List the types of traffic signal maintenance classifications
• Create the types of documents required for maintenance
• Describe typical maintenance activities
• Develop a traffic signal maintenance agreement
• Design basic phasing of the intersection
• Devise an appropriate data collection plan operating a signalized intersection
• Calculate signal timing for both actuated and coordinated operational strategies, including pedestrian clearance intervals
• Implement traffic signal timing and phasing plans

In order to receive credit for completion of the course, the participant must pass a final quiz built at the end of the course and follow the instructions to submit their results to PennDOT.

The course includes nine modules plus one final exam; an estimated completion time of the entire course is seven hours (includes review time). Any module may be viewed as many times as desired.

PennDOT provides continuing education credits (3 PDHs total) for completion of all modules, including the final exam. Follow the instructions on the Final Exam module to submit proof of completion to PennDOT to receive a Certificate of Completion.
