Bearing

This is the whole circle bearing taken in a counter clockwise direction for right hand side driving (RHD).

North is 0 degrees bearing.

Besides giving the orientation of the legs of the roundabout it is used to derive the angle between legs for use in the accident prediction.

Accidents increase as the angle between legs reduces below 90 degrees. Small values should be avoided.
