Hi Mirko, SUMO only supporting a constant lane width is indeed a difference with respect to OpenDrive and would explain what I've been seeing. Good to know, thanks! I did not use *--opendrive.min-width, *no, so the resulting edges were mostly coming straight out of netconvert. I used something like:
*netconvert --opendrive-files myfile.xodr -o myfile.net.xml --sidewalks.guess true --crossings.guess true* Kind regards, Ruud On Tue, Jan 30, 2024 at 3:56 PM Mirko Barthauer <[email protected]> wrote: > Hi Ruud, > > > > in general importing an OpenDrive network will result in some > simplifications.
