  • Balance Mobility and Access
  • Improve Safety
  • Reduce Congestion
  • Extend the life of Infrastructure

Roundabout Operational Characteristics Allow for:

  • Capacity at Intersection, less roadway width 
  • Flexible driveway and intersection spacing versatility
  • Less queuing
  • Roadway Geometric Flexibility
  • Slower & consistent speeds
