Intersection Safety, Design, and Capacity (1 Day Hybrid Online Class)
February 17, 2021
7:45am EST – 4:00pm EST


This hybrid online class will combine both live instruction and independent online work that you will complete during the day.  Independent work will include quizzes, readings, videos and short assignments.  Access to a computer with a webcam (either a camera that is built into your laptop or one that connects via USB), a reliable internet connection and a workspace that is free from distraction and noise will set you up for success.

This course is designed to give the participants an understanding of the planning, design, capacity, and operations of signalized intersections.  As the first step in the process for signalizing an intersection, the type of data necessary to conduct an analysis will be reviewed.  Participants learn of how to choose the type of traffic control device that should be installed.  They will learn the advantages and disadvantages of each type of control as well as signal and stop sign warrants.  They will estimate the capacity of an intersection and how the signal timing will affect the capacity.  Software will be demonstrated to show how the timing for optimizing the operation of a signal can be determined.  The MUTCD standards and guidelines for signal head location, markings, and signs will be reviewed.

This class is developed for engineers & project managers (design, traffic, safety, utilities, maintenance, and operations), transportation & land use planners, agency directors, Inspectors, safety data collectors, managers, and analysts.
