Traffic Signals

This is a self-study introductory traffic signals course that provides an overview of traffic signal procedures to Department personnel, municipal officials, planning partners, contractors, developers, consultant engineers, and other traffic signal stakeholders.

Participants will understand the various laws, regulations, standards, policy, and guidance information provided by the Department along with understanding the various components of a traffic signal. The course also serves as a refresher for experienced staff or as an introduction to additional subjects related to traffic signals outside of their current job duties.

This course is intended to be a high-level overview of various traffic signal items.

At the end of the course, you will be able to:

- Locate and navigate the various publications related to traffic signals in Pennsylvania

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 seven 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.

Module 6 will introduce you to the signal timing and phasing. This includes controller elements such as cycle length and phases, pedestrian timing requirement, pre-times and actuated signal control, and system control.
