NETCONVERT
From 30.000 feet
NETCONVERT imports digital road networks from different sources and generates road networks that can be used by other tools from the package.
- Purpose: Road networks import and conversion
- System: portable (Linux/Windows is tested); runs on command line
- Input (mandatory): Definition of a road network
- Output: A generated SUMO-road network; optionally also other outputs
- Programming Language: C++
Usage Description
NETCONVERT is a command line application. It assumes at least one parameter - the combination of the name of the file type to import as parameter name and the name of the file to import as parameter value. So, for importing a network from OpenStreetMap one could simply write:
netconvert --osm my_osm_net.xml
and for importing a VISUM-network:
netconvert --visum my_visum_net.net
In both cases, as no output name is given, the SUMO network generated from the imported data is written into the file "net.net.xml". To write the network into a different file, use the option -o <FILE>. If you want to save the imported VISUM-network into a file named "my_sumo_net.net.xml", write:
netconvert --visum my_visum_net.net -o my_sumo_net.net.xml
Many further parameter steer how the network is imported and how the resulting SUMO-network is generated.
Supported Formats
Import
NETCONVERT is able to import road networks from the following formats:
- "SUMO native" XML descriptions (*.edg.xml, *.nod.xml, *.con.xml, *.tll.xml)

Export
NETCONVERT is able to export road networks in the following formats:
- SUMO (*.net.xml)

Warnings during Import
Several types of warnings and errors with different levels of severity may be issued during network building.
| Message | Explanation | Recommended Action |
|---|---|---|
| Error: Could not set connection ... | A connection definition could not be applied because the lanes do not exist or do not share a common junction | Check your input files |
| Warning: Removed a road without junctions ... | Isolated road is removed from the network | |
| Warning: Not joining junctions ... because the cluster is too complex | The heuristic for option --junctions.join cannot handle a complex junction | Inspect the mentioned nodes and provide a join-description manually. |
| Warning: Found angle of ... degrees | An edge has an unusually sharp turn somewhere in the middle | Inspect the mentioned edge for correctness. Warning may be suppressed using option --geometry.max-angle. |
| Warning: Warning: Found sharp turn with radius ... | An edge has an unusually sharp turn where entering or leaving an intersection | Inspect the mentioned edge for correctness. Problems may be corrected automatically by setting option --geometry.min-radius.fix. Warning may be suppressed by setting option --geometry.min-radius. |
| Warning: For node '...': could not compute shape. | The shape of the junction area could not be computed | Inspect the mentioned node and maybe provide a custom node shape. |
| Warning: Junction shape for '...' has distance ... to its given position. | The shape and location of the junction area is suspicious. | Inspect the mentioned node and maybe provide a custom node shape. Warning may be suppressed by setting option --geometry.junction-mismatch-threshold. |
| Warning: The traffic light '...' does not control any links; it will not be build. | The traffic light at the given node sits at a junction without connections or the node was removed altogether. | Inspect the mentioned node if it still exists. Can usually be ignored. |
| Warning: Splitting vector close to end ... | A geometry computation somewhere deep in the code is suspicious. Often related to computation of internal lanes at intersections with bad shape. | Ignore for lack of sufficient information (or try to narrow down the problem by building smaller sections of the network). |
