Grading and Drainage Design of Modern Roundabouts

Modern roundabouts are a proven and effective safety improvement for roadway intersections. The main focus of roundabout design documentation has been in its traffic capacity and geometry. Once these features are set, the vertical design (grading and drainage) becomes the most critical portion of the design execution and the main component in determining the construction cost of roundabouts. In this interactive online course, engineers, architects, planners and contractors will learn design techniques and best practices to develop efficient roundabout grading and drainage designs.
