• What are the safety benefits of having a Roundabout verses a Traffic Signal?
  The benefits of a roundabout versus a traffic signal have become quite evident over recent years. Roundabouts reduce vehicle delay, roundabouts reduce vehicle emission, roundabouts reduce accident frequency and severity.
  
• What is the approximate size of a Single Lane Roundabout?
  The diameter of a single lane roundabout ranges from 110 ft to 120 ft.
  
• What is the approximate size of a Double Lane Roundabout? 
  The diameter of a double lane roundabout ranges from 165 ft to 180 ft.
  
• What is the difference between a Traffic Circle and a Modern Roundabout?
  A common traffic circle does not have the capacity nor the accident reduction capability of a modern roundabout. A traffic circle does not have the geometric design standards that exist with today's modern roundabouts.
  
• What is the maximum roadway grade on which a Roundabout can be placed?
  It is recommended by the Federal Highway Administration that the modern roundabout have approach grades of no greater than 3% to 5%.
  
• Are there standards and is it simple to design a modern roundabout?
  The Traffic Group, Inc. has gone through years of extensive training, both on a national and an international basis, to understand the "nuances" of designing today's modern roundabouts. "Tweaking" of poorly designed roundabouts can significantly increase capacity and reduce accident severity by simply making minor changes to the entrance radii.
  
• Does my private property need to conform to rules and regulations under the MUTCD?
  Maryland Law now states that private property owners in residential communities, commercial communities, and retail communities, must be in conformance with the Manual on Uniform Traffic Control Devices relating to signing and markings. Failure to do so could lead to unnecessary accidents and potential lawsuits.
