Many jurisdictions are looking for alternative intersection control methods to improve safety and carry more traffic without widening roadways. Roundabouts provide one of those methods.  Roundabouts are a common form of intersection control used throughout the United States. They are becoming more popular based on the multiple advantages to safety, operations, and aesthetics. However, as agencies become increasingly familiar with these types of intersections, it is important to understand both advantages and disadvantages, which this workshop addresses.

Selection and design of a roundabout, as with any intersection treatment, requires the balancing of competing objectives. These range from transportation-oriented objectives like safety, operational performance, and accessibility for all users to other factors such as economics, land use, aesthetics, and environmental aspects. This workshop highlights roundabout principles, providing participants a foundation, when combined with experience will produce favorable outcomes that benefit the traveling public and community.

Module 1: Roundabout Considerations

Joseph E. Hummer

Joseph E. Hummer, PhD, PE, is the Staff Engineer in the Mobility and Safety Division of the North Carolina Department of Transportation (NCDOT).  Joe is one of the foremost authorities on unconventional intersection and interchange designs practicing today.  He began researching the designs in 1990, has published numerous articles about them, and has invented several new intersection and interchange designs.  His two-part series in the ITE Journal in 1998 helped spark interest in the area.  More recently, he was a co-author of the FHWA informational report on six of the most promising designs, he was the Principal Investigator of the FHWA research project investigating the effects of diverging diamond interchanges, and he was the primary author of the FHWA guidebook on superstreets.  Joe was a Professor at North Carolina State University and was Chair of the Department of Civil and Environmental Engineering at Wayne State University before joining NCDOT in May 2016.

Who Should Attend

The workshop is designed to address the needs of a variety of learners, including the general public, policy makers, transportation planners, operations and safety analysts, and conceptual and detailed designers, as well as those interested in simply learning more about roundabouts.
