Re: [sumo-user] Resolve network warnings

If you recreate the roundabout you can change the radius at will and if the radius is large enough the warnings will disappear. However this would not reflect the real-world geometry. The root cause is the wrong number of lanes which is even easier to fix in netedit.

Thanks for your response. What about the warnings of the roundabouts?  Do you confirm removing this roundabout and recreating it as explained here (Converting an intersection into a roundabout)? https://sumo.dlr.de/docs/Netedit/neteditUsageExamples.html

warnings:
Warning: Found sharp turn with radius 7.94 at the start of edge '-23537059'.
Warning: Found sharp turn with radius 8.65 at the end of edge '-23537059'.
Warning: Found sharp turn with radius 8.26 at the start of edge '1149894368'.
Warning: Found sharp turn with radius 7.71 at the end of edge '1149894370'.
Warning: Found sharp turn with radius 8.65 at the start of edge '23537059'.

I cannot see the connections but those messages may be normal, as by default netconvert will reduce the allowed speed inside intersections depending on the curvature. Please look at the options --junctions.limit-turn-speed and --junctions.limit-turn-speed.min-angle.

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.
