Dear @Jakob Erdmann,

Thanks for your response.
I'm trying to automate this process, but users usually don’t have access to NetEdit.
Is there any alternative way to handle this, or should I go with Python scripting?
Please let me know if you have any suggestions or better approaches.


Thanks and regards,
Manohar

The --junctions.join algorithm reaches it's limit with intersections of this complexity. I recommend manual adjustments in netedit (https://sumo.dlr.de/docs/Netedit/index.html#processing_menu_options) so that it looks something like this:

If you do not wish to simulate pedestrians, it will also help to simplify the network with something like: --keep-edges.by-vclass passenger.

Dear sumo team,

I'm here to get the understanding on how to make a common signal for each junction, as of now I'm getting 3 signals, 

I'm using below command

" netconvert --osm-files osm_file.osm.xml --ramps.guess --junctions.join --junctions.join-dist 20.0 --junctions.scurve-stretch 1.0 --tls.guess-signals --tls.discard-simple --tls.join --tls.uncontrolled-within --geometry.remove -t typemap_file.typ.xml --output.street-names --output.original-names --output-file output.net.xml "


I tried increasing or decreasing the junctions.join-dist 20.0  but its making overall network worse.

Also attached the network file for your reference, I need your assistance in removing the small signals nearby , it's making the bit odd in giving the signals to vehicles.

any predefined script is there mean suggest also !



Thanks and regards
Manohar c v
