Course Description

The Designing Signalized Intersections course is a new certificate-based, blended learning program that provides students with a comprehensive coverage of the technical elements of designing signalized intersections.  This training program consists modules covering major topic areas, which will include overall introduction discussing the design of traffic signals, geometric design for signalized intersections, and detailed coverage of signal control elements.  This course will provide a full understanding of the practice of designing signalized intersections including interactive instructor-led discussions and pre-recorded sub-modules accessible anytime within the program period to accommodate the pace and schedule of the student.  This program is targeted towards practitioners early in their careers with a focus on foundational knowledge and skills necessary for designing traffic signals from planning through implementation.  Additionally, students will have the opportunity to interact directly with a live panel of experts as they explore the intricacies of real world examples.

Four live instructor-led discussion sessions will also provide real-world case studies, addressing emerging issues such as bicycle signals, cybersecurity, and sustainability among other topics. These live discussions are designed and intended to reinforce the content learned from the modules completed prior to the live session. Individuals who successfully complete this training program will receive an ITE Designing Signalized Intersections Certificate.

Here is a brief summarization of the topic areas covered under each module:

Part 1: Course Introduction

The introduction will provide an overview of the course purpose and intent, intended audience, delivery approach for content, schedule, and the requirements to receive the ITE Designing Signalized Intersections Certificate.

Part 2: Geometric Design

These modules address the fundamentals of the geometric design of intersections and the choices of traffic control.  Topics addressed include the type of intersections and traffic control, sight distance and sight triangles, swept path and curb radii, the design of left and right turn lanes, and safety assessment.

Part 3: Signal Control

The modules on traffic signal control begin with an introduction to the overall topic touching the history of intersection signalization, purpose, alternatives, benefits and challenges, justification, human factors and safety, queueing, sustainability, and basics of signal phasing and sequencing , as well as on-going maintenance and operational considerations. The course continues with material on the physical design infrastructure of a signalized intersection including signal heads, controllers, detection and electrical facilities. The next group of modules cover the various facets of signal timing such as the basic timing considerations, preemption and priority, bicycle and pedestrian treatments, and special signal applications as well as coordination and timing strategies with their performance measures.  The course closes with content on system control, intelligent transportation systems, and an overview of systems engineering, connected vehicle applications, cybersecurity plus the issues surrounding design document development.

Course Learning Objectives
Upon completion of this course, participants will be able to:
