There are a variety of roundabout designs that deviate from the traditional circular roundabout. These include (but not limited to):

  • Teardrop/raindrop
  • Dog bone
  • Dumbbell
  • Tennis Ball
  • Peanut
  • Turbo
  • Squarcle
  • Cut through
  • Hamburger

Each of these can be used in unique situations where the cost, effectiveness or safety of traditional circular roundabouts is not optimal. Each of these non-circular roundabouts needs to be designed carefully taking into account a raft of complex factors.
