Junction Box over Roundabout
There are three scenarios where it is necessary to apply a Junction Box over a Roundabout (JuBra):
- Exit options (TRs) must be set to red on the roundabout because the roundabout is built in such a way that driving all the way around is not allowed.
- The roundabout must give appropriate instructions (turn right, straight ahead or left over the roundabout) in order to be able to use the directions from the signs at the roundabout.
- For an exit segment, depending on which side you approach the roundabout, you have to work with different direction names.
