Design of At-Grade Intersections
September 29 and 30, 2026 – 9:30am to 12:30pm EST
PDHs AVAILABLE
6 Professional Development Hours can be granted for this course. No partial credit available. Attendees must attend at least 90% of the webinar to get 6 PDHs.
WHAT THIS IS ABOUT
This workshop will introduce participants to the key concepts, procedures and standards involved in the Design of At-Grade Intersections. Topics covered will include the basics of intersection design: intersection capacity, design criteria and controls, sight distance and geometric design elements. Additional focus will be given to other important issues, including turn lane design, channelization, pavement marking, modern roundabouts, accommodating bicycles and accommodating pedestrians. All of these topics will be presented in relation to their direct application to the design of at-grade intersections. Participants will have opportunity to share opinions and personal experiences in order to broaden the classroom experience.
WHO SHOULD ATTEND
Local and state government employees, consulting engineers, and others with an interest or involved in the design of streets and roadways.
