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

Date: 6/23/2020 8:00 AM - 6/23/2020 4:30 PM

Location: Hadley Farms Meeting House
41 Russell Street

Hadley, Massachusetts




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
• Apply signing and marking suggested practices
• Apply design strategies for pedestrians and bicyclists

Transportation professionals with at least one year of working experience.

    Mr. Sides’ first roundabout was the pioneering Clearwater Beach Entryway Roundabout in 1998.  His roundabout projects have won nine engineering, planning and construction awards.  He teaches roundabout courses for the National Highway Institute and the University of South Florida.  Mr. Sides has extensive experience in presentations and public outreach.  He has published nine articles on modern roundabouts.

    Mr. Sides is a long-serving member of both the Transportation Research Board (TRB) Roundabout Committee and the Institute of Transportation Engineers (ITE) Roundabout Committee, and he is chair of the TRB Sub-Committee on Autonomous Vehicles and Roundabouts. TRB is an arm of the National Academy of Sciences. He is a certified Professional Transportation Operations Engineer (PTOE), an accredited member of the Congress of New Urbanism (CNU-a), a certified bicycle safety instructor (LCI), and a certified bicycle group Road Leader/Road Master.  His peers have named him Engineer of the Year four times (2004, 2008, 2011, and 2013).
