  1. Roundabouts in Massachusetts State of the Practice at MassDOT

  2. Roundabouts in Massachusetts • Overview of current MassDOT’s approach to “modern roundabouts” • Negative connotation to the roundabout due to the “rotary” design • Changing driver behavior starts from the top with the Drivers Manual and education of the future motorists in the Commonwealth • Winning the public over to the benefits of a roundabout versus the traditional intersection design

  3. Roundabouts in Massachusetts “Text Book Design” vs. the New England Intersection – Why we have a tough time selling a roundabout. - Standard design layout is hard to obtain and build without ROW takings.

  4. Roundabouts in Massachusetts • What are our biggest challenges: • Overcoming the stigmatism of the “rotary” • Addressing the peak-hour volume flows • Providing for accommodation of all users • Gaining public trust in the dedicated lane assignment configuration of a roundabout • Documenting the safety benefits of the reduction in crashes at roundabouts • Obtaining buy-in from the Public Safety community

  5. Roundabouts in Massachusetts Design Challenges – • Achieve desired capacity with 2 lanes • Provide better pedestrian access • Offer improved Aesthetic qualities • Accommodate the bicycle community

  6. Roundabouts in Massachusetts So where are we now? MassDOT has begun to request project designers and private developers to consider roundabouts as a “first option” to address a uniform approach to traffic operations and providing accommodation for all road-users. Roundabouts are now being considered as viable options for interchange junctions.

  7. COMPLETED IN DESIGN Roundabouts in Massachusetts

  8. Roundabouts in Massachusetts Next Steps for MassDOT • Working with the Central Transportation Planning Staff (CTPS) from the Boston MPO on the development of a “Roundabout Planning Screening Tool” to assist designers in when to consider a roundabout versus a signalized intersection. • Develop a “Local Community Reference Guide” to provide details on the benefits of roundabouts on traffic calming and livable streets. Ensure that a roundabout is considered for the correct reasons.
