Option to Forcefully Join Junctions Despite Parallel Edges in Netconvert

[henrigrossmann]

Description:
I am using SUMO's netconvert to generate and process a road network, but I am encountering the following warning:
Warning: Not joining junctions 1628096906,248152002,3256888393,7071685943 (parallel outgoing 149864364#0,741020259#3).

Question:
When joining these junctions manually in Netedit, it works perfectly. Therefore, I would like to know if there is a way to force netconvert to join them even though they have parallel incoming/outgoing edges or if there is a workaround that has the same effect.

I have attached the configuration file used for the network conversion, which should enable junction merging. The current focus is on the junction cluster around edge 572748503_1.

the relevant angular threshold is now user-configurable.

Thank you very much! Quick question from my side: what was the idea behind excluding parallel edges from joining. Just so we know when to be careful 👍

[namdre]

anecdotally, this was causing huge clusters with parallel edges belonging to totally different roads (i.e. whenever you have a dense grid of roads).

Thank you very much for the quick solution and explanation! Highly appreciate your responsive support!
