Signalized Intersections Part III – Treatments

Vincent D. Reynolds, MBA, PE

Intersections occur along roadways in order to connect intersecting streams of traffic. Several conflicts can occur at intersections which involve pedestrians, vehicles, and bicycles. These conflicts can be classified as merging, diverging and crossing. The basic function of signalized intersections is to sequence right-of-way between intersecting streams of users. Research has shown that, under the right circumstances, the installation of traffic signals will reduce the number and severity of crashes.

This course will provide methods for evaluating the safety and operations of signalized intersections and the tools to remedy the deficiencies.

This course is based on the document “Signalized Intersections,” published on the website of the Federal Highway Administration.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
