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.


Local and state government employees, consulting engineers, and others with an interest or involved in the design of streets and roadways.
