Thank you Jacob! This again was very helpfull.
Because I want to generate the .net.xml automatically without using Netedit, I searched for a solution to set the stoplines on the right position automatically. I found a solution by
calculating and adjusting the radius at the junction. See the result below.
I’m still having trouble with the bicycle crossings though, because they have no radius. I think it’s because the incoming edges of the bicycle crossings are lengthen for some reason,
is that correct? And what kind of reason could that be? Are the edges maybe too short? If there is another solution to tackle this problem I’ll be happy to know too.
In my opinion using the radius is still a form of symptom control. I hope there will come a better solution for this in time.

The junction shape is indeed strongly influenced by the start/endpoints of the edges.
By default these points are indentical with the junction center but you can set them anywhere you like.
In your example the vehicle edge coming from the right uses the default endpoint of the junction center.
The computation logic is this:
- compute junction shape based on edge shapes, the intersection of neighboring edges and the specified junction radius
- shorten or lengthen edges that reach beyond the junction shape or that do not reach it for some reasion
Note, that a custom lane shape completey overrides the computed shape so you may still have invalid lane geometries depending on what you specify.

Thank you for your answer Jakob,
So if I change the shape of the junction, I should get the stoplines at the right position? I have the start and end positions of the edges, so it should be possible
to make a shape by connecting them
In my opinion the shape of the junction should be determined by the start and end points of the edges that are connected to the junction and not the other way
around. Maybe you could think of another solution for the future?

The waiting position of the vehicles is mainly determined by the junction shape. While you defined the connection shapes to start to the left of the bicycle crossing,
the junction shape starts to the right of it and thus the vehicle edge is made longer to meet the junction shape.

Dear SUMO-users,
Last time I messaged, I had some issues regarding pedestrian crossings en bicycle paths. Thanks to your advices I managed to get a near real visualization of
the controlled intersection. However I still see some strange things.
The stoplines on the left approach are drawn to for to the right, behind the (controlled) pedestrian crossing and bike lanes. This is also shown on the bicycle
paths, so the cyclists on the intersection instead of in front of it. Why is this happening? Do I have to configure an extra option on netconvert?
The SUMO native files and the .net.xml are enclosed here. I call netconvert with the following options:
netconvert --node-files=Output/KR27.nod.xml --edge-files=Output/KR27.edg.xml --connection-files=Output/KR27.con.xml --type-files=Output/all.typ.xml --tllogic-files=Output/KR27.tll.xml
--no-turnarounds=true --junctions.corner-detail=5 --output-file=Output/KR27.net.xml
