I have downloaded real city map from openstreetmap in .osm format and has obtained net.xml file by using netconvert but could not obtain edges file(edg.xml) and node file(nod.xml). So, need help for these conversions.
Open NETEDIT and load your network (*.net.xml). Then from go to File -> Save plain xml . This way you can easily create the nod.xml and edge.xml files.
