2015 Focus - Stockdale Roundabout Design

Civil Designer has two different methods for designing traffic circles: ADD ROUNDABOUT and ADD MINI-CIRCLE. The difference between the two methods is summarised below:

  • More than 4 incoming legs
  • Can be non-circular
  • Leg & circle road separation
  • Uses Stockdale method
  • Defined by CAD input
  • Kerb lines can be any shape
  • Mini-Circle
  • Up to 4 legs
  • Circular only
  • Primary road runs through mini-circle
  • Circle draped onto intersections
  • Restricted to specific settings
  • Circular Kerb lines

  • Civil Designer's incorporation of the Stockdale Method involves:
    1. Indicating crown lines on the roundabout circle and approach roads such that they coincide. These points of contact are called 'kiss points'.
    2. Calculating the chainage of each kiss-point along the circle crown line, using one of the kiss points as the starting point.
    3. Plotting the start and end point at each approach crown line on a long section (on the same chainage system).
    4. Creating an s-curve for each approach line using the kiss points and the known grades.
    5. Finally, determining the circle crown line (red alignment below) by fitting a spline through all the kiss-points.
