Junction Box en rotondes
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.
The Junction Boxes are drawn all over the Roundabout. Any by-pass segments remain outside the Junction Box.
A Junction Box over a Roundabout (JuBra) is used, among other things, to get the instructions left, straight ahead, right and turn around on roundabouts and to enter RS/TI set per approach direction.
