invalid junction shape at roundabout #12624

Open namdre opened 1 year ago

namdre commented 1 year ago

the junction space is to small to contain the curving internal lanes that stay within the roundabout.

@mehmetnedimyavuz this is from your network (#12618). If it bothers you, you can work around this by setting custom end positions for the edges that enter the roundabout (https://sumo.dlr.de/docs/Netedit/neteditUsageExamples.html#using_set_geometry_endpoint)

Actually I set junction radius=0 for the 4 junctions that make up each roundabout (#12426). But when I changed radius to "default". It seems work image

Thanks for the info. It's supposed to generated "safe" intersections with all radius values though.
