netconvert Warning: Could not write OpenDRIVE geoReference #8159

Closed samidh93 closed 3 years ago

samidh93 commented 3 years ago

I imported openstreetmap osm to sumo netedit and add demands .rou.xml. I exported the network as .net.xml and switch to sumo-gui and save sumocfg file. I ran the simulation and everything was working. last step i tried to convert the network .net.xml to opendrive xodr but i got the following message:

netconvert -s map2.net.xml --opendrive-output map2.xodr 
Warning: Found angle of 144.82 degrees at edge '376269501#2', segment 1.
Warning: Could not write OpenDRIVE geoReference. Only unshifted Coordinate systems are supported (offset=-387572.76,-5821156.19)
Success.

Unfortunately, the output xodr file could not be processed for later purposes. I tried different osm maps with different sizes and complexity but i got always a lot of warnings. Any help on this issue? is there a better way to use netconvert? is it faisable to convert osm map with sumo at all?

If you need a geo-referenced xodr file, add option --offset.disable-normalization during initial osm import. Regarding other warnings (i.e about angles), note that you are converting from a format with comparatively low geometric detail into a high detail format. Netconvert does some smoothing but this is often guesswork. I know projects that have successfully used used osm-derived xodr. Are the other warnings you are getting on the netconvert side or from other applications that are using the generated xodr?
