Re: [sumo-user] Resolve network warnings

The following answer assumes that we're talking about this roundabout: https://www.google.com/maps/@54.9880624,-1.5482275,3a,75y,95.49h,61.36t/data="">

OSM doesn't encode lane numbers so the default of 2 lanes gets used for the main road of type "highway.primary".

Having two lanes doesn't do justice to the geometry of the place and this causes the warnings. If you change laneNumber to 1 the warnings disappear.

regards,

Jakob

Hello!

I am facing many warnings in my network. Several of them related to a roundabout as shown in the picture below:

I am thinking about removing this roundabout and recreating it as explained here (Converting an intersection into a roundabout): https://sumo.dlr.de/docs/Netedit/neteditUsageExamples.html But I am not sure if it is the best solution.

Beside that, I also have the below warnings:

Warning: Speed of straight connection '-604070588_1->-33040725_1' reduced by 7.28 due to turning radius of 20.06 (length=7.15, angle=36.28).
Warning: Speed of straight connection '33040725_0->604070588_0' reduced by 5.53 due to turning radius of 27.30 (length=9.84, angle=36.28).
Warning: Speed of straight connection '33040725_1->604070588_1' reduced by 6.14 due to turning radius of 24.65 (length=8.86, angle=36.28).
Warning: Speed of straight connection '713933105_1->604070587_1' reduced by 6.08 due to turning radius of 24.89 (length=11.41, angle=42.13).
Warning: Speed of straight connection '-604070587_0->-713933105_0' reduced by 7.63 due to turning radius of 18.73 (length=8.49, angle=42.13).

By clicking on them it does not go to the warning place on the network and I have no idea on how to get rid of them.

Any ideas and suggestions would be appreciated.
