Signalized Intersections Part II – Project Process and Analysis

Vincent D. Reynolds, MBA, P.E.


Course Outline

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 4 hour course is the second part of a three part series and will introduce to the reader to the project process and analysis methods of signal design. Part II provides tools that can be used to evaluate the safety and operational performance of an intersection.

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


Learning Objective

At the conclusion of this course, the student would have learned the following:

Intended Audience and Benefit

This is intended for planners, traffic engineers, highway engineers, designers, operation analysts, project managers, or any persons working in civil engineering field or anyone with an interest in signalized intersections.

Course Introduction

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.

Course Content

This course will introduce to the reader to the project process and analysis methods of signal design. Part II provides tools that can be used to evaluate the safety and operational performance of an intersection. Chapters 5-7 are the sections that are required to be read in order to complete the quiz for this Part of the series; the remaining chapters are covered in Parts I and II of this course.
