Abstract:

Well-designed Modern Roundabouts enhance the achievement of Access Management principles

  • Maintain Integrity of Arterials

  • Balance Mobility and Access

  • Improve Safety

  • Reduce
    Congestion

  • Extend the life of
    Infrastructure

 

 

Roundabout Operational & Safety Characteristics:

  • Driveway and intersection spacing versatility

  • Geometric flexibility (properly designed)

  • Less queuing

  • Slower & consistent speeds

  • Reduces speed differentials

  • Less conflicts

 

System Effects of Roundabouts

  • Roundabouts work well in series

  • Roundabouts and signals are compatible

  • Roundabouts may reduce the need for expensive roadway or structure widening

  • Roundabouts provide substantial flexibility for driveways and side street spacing and design
