2. Mission and Goals
a) Task Force findings
Task Force Principles
• Holistic view of roundabouts
• Frequent communication and open
• Avoid duplication with the TRB Task Force and other organizations
• Participation is not limited or defined by position on Task Force
• Provide products for the public and profession
• Disseminate information and products
• Objectivity is desired (show good and bad points) rather than prescriptive and
To provide products and services that advance knowledge of roundabouts within
the engineering profession and promote broader acceptance of roundabouts by the
Design Standards and Practices
• To serve as a forum for transportation practitioners to discuss design practices,
considerations, and standards affecting the design of roundabouts.
• To become a resource for and actively work with policy makers in the
transportation industry to develop better and more refined design standards.
• To provide up to date and accurate information and guidance to the
profession on modern roundabouts.
• Help collect and study the results of existing roundabouts to assess the strengths
• Gather the latest research and developments in roundabout safety and design.
• Objectively help practitioners by clearly illustrating the benefits, limitations,
and considerations of roundabouts.
• To educate transportation engineers and decision makers (government
officials, highway directors, State DOT’s, and developers) of the benefits
associated with roundabouts.
• To develop and disseminate educational materials for both professional and

3. Task Force Initial Findings
a) Identified Gaps and Needs - See Attached
DISCUSSION: All present were asked to bring forward one or two points of focus
for the Task Force – based on summary provided or other needs identified.
• Carbon footprint savings, greenhouse gases
• Education of engineers, planners, policy makers and decision makers
• Public awareness and driver education
• Signing and striping varying from state to state
• Present of wide body of information into a single source/one spot
• Get more engineers working on roundabouts
• De-mystify roundabouts in the profession
• Civil engineering students getting only prescriptive design education, if
• Networks of roundabouts – queue interaction between roundabouts in
a grid or corridor
• Workshop of design principles
• Outreach material for a variety of audiences
• Architects and planners introducing circular intersections that haven’t
had engineering review
• Consistency of application and review
• National certification as a training method
• Mainstream roundabouts
• Roundabouts are creative
• Incident management
• Work zones
• Access control
• Construction costs
• Beyond collector/local junctions
• Lighting standards
• Safety benefits need to be identified – SAFETY- LU
• Quality of life
• ADA issues may be deal breakers for installing
• Understanding appropriate applications
• Getting additional info into MUTCD to improve visibility/priority
• Separation of multi-lane and single-lane roundabouts
• Major media exposure – National spokesman (i.e. Michael Phelps as
national spokesman, special report on news shows)
• AASHTO may need to be involved in the education process
• Roundabout safety audits
• High speed approaches
• Sight distance
• Guidance on volumes at intersections
• When do we install and when don’t we – education
• Pedestrian safety
• Life cycle costs and being good stewards of the public money
• Dissemination of information in a rapid manner
• Sight impaired and non-sight impaired pedestrian issues
• Should be a tool – starting down a path similar to traffic calming,
• Design and analysis standardization
Education was the need most heard about from the meeting attendees.
Some of these issues were covered under the NCHRP 572 (NCHRP 3-65 Project) and
are being incorporated into NCHRP 3-65A Project - An Update to the FHWA
Roundabouts: an Informational Guide – due out in August 2009. Lee Rodegerdts, PI
of the project, stated that education is not addressed significantly in the
aforementioned research projects and would be a good area for this committee to
focus some efforts.
Additionally, some of the gaps and needs listed and mentioned are better defined
as research projects and will be referred to the TRB Roundabout Task Force.
From list of gaps and needs, identify where issues are already being addressed by
other agencies or efforts.
4. Product Development
Discussion about what products can be generated from the Task Force. Project
committees will be needed to perform these projects.
a. Sponsored Sessions
Meeting attendees voted informally, by show of hands, that the Task Force
should support a sponsored sessions at the 2009 ITE meetings.
ACTION: Deadline for papers is August 25, 2008. – Isebrands submitted
session themes and speaker ideas to ITE on August 25, 2008.
b. ITE Journal
Themed edition of the Journal is available for the February 2009 issue.
• Deadline for having content ready is November 15, 2008.
• 4 to 5 articles of ~3,000 words. Articles undergo review.
• “Newsies” which are shorter articles, 750-1000 words that look at smaller
projects, case studies, etc.
