FHWA-NHI-380096 Modern Roundabouts: Intersections Designed for Safety

The modern roundabout is a proven strategy for improving the safety and operations of intersections. The physical characteristics of a well-designed modern roundabout reduce the frequency and severity of intersection crashes for all users including pedestrians and bicyclists. This course highlights the benefits of modern roundabouts and gives participants the fundamental knowledge needed to plan and consider applying roundabout intersection projects in their area. This course is an introductory level course with a blend of technical and non-technical planning, design and operations considerations.

Upon completion of the course, participants will be able to:
• Distinguish a modern roundabout from other types of circular intersections
• Describe the safety advantages of roundabouts
• Describe the operational advantages roundabouts provide
• Identify what type of locations roundabouts may be appropriate
• Describe strategies to overcome common barriers to implementation of roundabouts, such as negative public perceptions
• Describe the key considerations when planning an area's first roundabout
• Apply basic traffic operational models and capacity calculations for roundabouts
• Describe key geometric design principles of a modern roundabout
