Re: [sumo-user] connecting bike lane + generic lane to a single lane yields a warning, despite zipper junction

2022-02-02 Thread Rob Maris

Thanks for clarification, Jakob,

At the time I inserted a zipper junction just at the start of the edge without 
bicycle lane - in order to (believe to) get rid of the warning, I already 
concluded that something is overseen in the behavioural rules: Two normal lanes 
merge (in a zipper) to one lane without warning, while merging a normal lane 
and a bicycle lane results in a warning.

In a way, that warning message is no longer needed.It dates to a time where 
multiple connections to the same lane were unsafe in SUMO and could cause 
collisions.
This has long been fixed and now multiple connections to the same lane are either 
resolved with zipper logic or (for any other type of >junction) with 
right-of-way rules that give priority to one of the connections.
In the case you describe, the cars moving from north to west would have yielded 
to the bicycles that are coming from the north.With your change, they are doing 
zipper merge. Which one of those two behaviors is more realistic probably 
varies between localities.

Originally (from OSM wizard) the small zipper junction that resulted from a manual 
splitting of the upper edge was not present. The >>bike lane from the north got 
into the residential lane, together with the standard lane (see screenshot).
I'm wondering that the warning after insertion of a zipper junction is only 
"relocated just left of the zipper junction.

Since I'm doing clean-up of the network prior to doing other steps, this problem 
popped up >>yet...___
