You should read the main page on NETCONVERT before reading this.

OpenStreetMap-project

URL: http://www.openstreetmap.org/
Area: the complete world :-)
Demand data: not available
Extraction:
1. Networks/Import/OpenStreetMapDownload explains how to obtain OSM-data.
2. Networks/Import/OpenStreetMap explains how to create Sumo-networks from OSM-data using NETCONVERT.
Comments: A great source of networks and man-made infrastucture. However, infrastructure data and definitions are still changing which complicates import.

Frida-project

URL: http://frida.intevation.org/
Area: city of Osnabrück
Demand data: not available
Extraction: netconvert --shapefile strassen -o frida2.net.xml --shapefile.street-id strShapeID -t frida.typ.xml --shapefile.type-id strTypID -v --proj "+proj=utm +ellps=bessel +units=m"
Comments: Not really applicable because the streets lack information about the number of lanes and the direction. Especially the second makes the converted network quite useless. Trying to use the option --shapefile.all-bidi solves the problem for inner-city roads but makes highway on/offramps bidirectional, too. The projection might be wrong as well, give --proj.utm a try.
