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
