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 <OUTPUT_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

NETCONVERT is able to import road networks from the following formats:
