Hello Jakob,
1) steps as follows (NETEDIT 1.2.0)
- open network
- open additionals
- save additions (dialog will appear, which seems superfluous, since I
just opened a specific file?)
- switch to TAZ mode with z
- select a TAZ
- disable the "keep" checkbox
- change a value in either the Source or Sink textboxes
- hit the Save changes button
- check the menu item
2) thanks!
3) this is not actually a zipper junction, but a junction belonging to
multiple other junctions that form an intersection (there is a single
(externally controlled) traffic light): see below, the one on the left
without traffic light lines is the current zipper one
I set the type to zipper cause cars arriving on the edge the is selected
in the image (blue) would only use the rightmost lane. Maybe a better
solution then is to include that junction in the complete intersection,
that is, control is as well with the same traffic light?
Thanks again,
Greets,
Menno

Hello,
1) I could not replicated the disabled menu item. Can you give exact
steps for this?
2) For the ordering-related error, see
https://github.com/eclipse/sumo/issues/5640
3) Zipper junctions only support lane-drop type junctions at the
moment. Real intersections with zippering are not supported at the
moment. To be more precise, zipper connections that cross other
connections before merging into the target lane are not supported.
Since the check for this is only done when a vehicle encounters an
unsupported intersection type, it may take a while for this error to
come up in your simulation.
Does the layout in your example reflect a real intersection where
multi-lane roads merge without prioritization ? I was not aware that
such things exist.
best regards,
Jakob

Hello all,
after a while away from sumo and simulations, I have picked this
up again now. Great to see the new features! Eg. being able to
edit taz items within NETEDIT is really helpful.
I have noticed:
* when changing 'source' and 'sink' values for edges belonging
to a TAZ, after hitting "Save changed", the "Save additionals"
menu item stay disabled. Only after for example moving a
detector can those changes then be saved to an additionals
file that had been opened and saved before.
* NETEDIT sometime saves TAZ items like this:
<taz id="P2" shape="1183.39,406.32 1188.58,398.44
1194.54,402.09 1190.31,410.36 1183.39,406.32" color="blue">
<tazSource weight="0.00" id="gneE120"/>
<tazSink weight="1.00" id="gneE120"/>
<tazSource weight="1.00" id="gneE121"/>
<tazSink weight="0.00" id="gneE121"/>
</taz>
Important here is source-sink-source-sink: SUMO will be unable
to read this and report an error. It seems odd that this is
incorrect, because it is valid XML and the order of the items
should (in my opinion) be irrelevant. Saving, closing, opening
and saving again of the additionals file solves the problem:
then we have source-source-sink-sink.
A question: given the junction in the picture below, SUMO
complains after a while of simulation: "Error: Zipper junctions
with more than two conflicting lanes are not supported". I wonder:
why? How to solve this?
Thanks, greets, Menno
