What is the minimum radius of a roundabout?

Entry Curb Radius – Entry radii at a single-lane roundabout typically range from 50 to 100 ft.

What is the purpose of roundabout design?

Roundabout design is an iterative process. well-designed roundabout achieves a balance of safety and efficiency. Good design is a process of creating the smooth curvature, channelization, and deflection required to achieve consistent speeds, well-marked lane paths, and appropriate sight distance. Roundabout

What do truck aprons look like on concrete?

From a distance the concrete looks like red paving stones. Truck aprons are used on roundabouts and slip lanes to compensate for the off-tracking of larger vehicles. Off-tracking is the shorter path that the rear wheels follow as a vehicle moves around a corner.
