Traffic design engineers are invited to a TRB webinar on Thursday, August 29, 2019, from 1:00 PM to 3:00 PM ET. The webinar will provide guidance that overcomes challenges of roundabout implementation and provides successful outcomes. During the last ten years, the roundabout implementation experience started to show how transferable a concept or design is to many locations. Existing research and guidance shares these basic concepts, but there is very little real-world experience to help decision-makers with these applications within the roadway network. Facing challenges with the public, design, signals and operations, traffic design engineers may use case studies, modeling assumptions, and traffic models to assist decision-makers in seeing the possibilities of a roundabout and address the challenges they are often concerned about.

This webinar features a presentation on modeling insights and shares two individual case studies of roundabout intersections at locations where the implementation experience played a significant role in achieving success for the roundabout. Presenters will also discuss how engineers may assist decision-makers in looking at their previously held assumptions about roundabouts and instead view them as a valuable tool in traffic design.

This webinar was organized by the TRB Standing Committee on Roundabouts.

Some registrants will need to pay $105 to attend this webinar.  Sign into to view registration information.

Webinar Presenters

  • Doug McClanahan, Washington Department of Transportation
  • Mike McBride, America StructurePoint Inc.
  • Mike Maurovich, America StructurePoint Inc.
  • Hillary Isebrands, Federal Highway Safety Administration

Moderated by: Daniel Spann, Barge Design Solutions

Webinar Outline

  1. Overview of traffic analysis modeling
  2. Overview of flexible needs and requirements
  3. Case study on roundabouts and regional bicycle trails
  4. Case study on roundabout operations near a railroad crossing
  5. Question and answer session

The first 90 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.

Learning Objectives

At the end of this webinar, participants will be able to:

  1. Describe how to design safer roundabouts through traffic analysis modeling
  1. Identify flexibility needed in roundabout implementations
  2. Describe how roundabouts may lower speeds to enhance pedestrian and bike integration outcomes
  3. Utilize other tools outside modeling to support the roundabout implementation experience

 Professional Development Hour Information

A certificate for 2.0 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For approved webinars, TRB’s webinar program awards Registered Continuing Education Provider (RCEP) Professional Development Hour (PDH) credits associated with participation only to the registered individual and not to other members of a group that view the webinar together. To receive PDH credits, please register as an individual and sign into the webinar from your personal computer. After doing this, you may join your group in a meeting room.  To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.

In addition, advance registration is available until just before the webinar starts. Once the webinar starts, you will be unable to submit your registration. Individuals that are registered for a webinar but do not receive their confirmation emails due to their organization’s internal firewalls should contact the TRB Helpdesk ( for assistance in signing in.

Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that TRB provides through as verification of your attendance to the Florida Board of Professional Engineers.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

This webinar was developed in March 2019. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP). Credit earned on completion of this program will be reported to RCEP by TRB. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005.
