Roundabouts

Roundabouts are a Proven Safety Countermeasure because they can substantially reduce crashes that result in serious injury or death. Roundabouts can:
  • Improve safety
  • Promote lower speeds and traffic calming
  • Reduce conflict points
  • Lead to improved operational performance
  • Meet a wide range of traffic conditions because they are
    versatile in size, shape, and design
