COURSE NO: C04-070
Characteristics of Successful Roundabout Projects
Course Highlights

This online engineering PDH course presents the characteristics of successful roundabout projects.


Roundabouts, modern versions of traffic circles and rotaries, offer superior safety, environmental benefits, and cost savings compared to traditional intersections. Implementing roundabout projects can be challenging, so understanding the key factors for success is valuable. Successful construction projects require effective coordination among designers, contractors, tradespeople, and suppliers. This course focuses on identifying the crucial characteristics necessary for achieving successful roundabout projects, including a detailed examination of roundabout advantages and a review of notable projects by the U.S. Department of Transportation.


This 4 PDH online course is applicable to civil and transportation engineers as well as other technical professionals who are interested in promoting the use of roundabouts.
