Thanks for the hint,
at this time I only note that update of the graph is not perfectly well, but I
guess that you know that.
Without zipper, the junction shows white and grey connections towards the same
target (see attachment, where the cursor lives).
Before that, I noticed some small graph behavioural habits, which all can be
managed by doing some mode changes.
Normally, changing from Network to Demand mode automatically updates junction
shapes. But only... when the junctions in Network mode occur as simple filled
circles. To accomplish that, I do beforehand M, then click in a junction,
before doing F3.
Only then, changed lane widths are visually updated as well.

Excellent!
the alt-4 is a bit counterintuitive. Why?. Because this action flag is default on, and I'd
interprete that as lane select (the more >>specific case related to the generic edge,

shift->>click works perfect for doing some casual lane operations.
I opted for narrowing instead of making a single wide lane after your advice.
Regarding the other problem of a never occupied lane before a junction: This has been solved by introduction of two lanes on the
>>junction output. But because after a few hundred meter a real narrowing to one lane was to be executed, the problem was
merely >>shifted towards that place (at a small junction to a side street). But because of the simplicity of that junction,

"conflicting" lane. Voilà!
Since I know that the drivers in the simulations behaves as real humans do :-),
during simulation, no accidents occur on the >>narrowing spot.

Either- toggle the 'clicking should select edges' button (Alt+4)
- or shift-click to inspect the lane
It is possible to have vehicles driving side by side on a wide line when activating the
sublane model (https://sumo.dlr.de/docs/>>>Simulation/SublaneModel.html) but
often it is simpler and more performant to use two narrow lanes instead.

Or can the extra wide lane be modeled such that passenger cars drive alongside? (e.g. when

Thanks for any help appreciated!
