Your usual strategy should be to replace a faulty junction or a cluster of nearby junctions with one correct junction by placing a new junction on top of the existing junction or group of junctions.

Cartouche tries to be clever and usually succeeds. When you place a junction it will look for neighbouring junctions and roads. It will replace the existing junctions (more than one) and connect the roads. If a little segment of road goes past the junction, it will be deleted automatically.

You should normally tick "enable all turns" when adding a junction. Cartouche will correctly handle one-way roads. You should then apply any additional turn restrictions.

How far away Cartouche looks for nearby junctions and roads depends on your zoom level. The close you zoom in, the closer you can place junctions to each other, and to roads, without them connecting. The mid zoom level of 100m/200ft is best for normal work.

If you zoom out one level, placing a junction will clear up junctions and dangling road ends in a wider area. Zoom in one or more levels for close work around complex intersections.

Do not place junctions at zoom level of 200m/1000ft or higher. It is too inaccurate.
