Exporting AequilibraE model to GMNS format#

After loading an existing AequilibraE project, you can export it to GMNS format.

example

As of July 2022, it is possible to export an AequilibraE network to the following tables in GMNS format:

  • link table

  • node table

  • use_definition table

This list does not include the optional use_group table, which is an optional argument of the create_from_gmns() function, because mode groups are not used in the AequilibraE modes table.

In addition to all GMNS required fields for each of the three exported tables, some other fields are also added as riminder of where the features came from when looking back at the AequilibraE project.

Note

When a node is identified as a centroid in the AequilibraE nodes table, this information is transmitted to the GMNS node table by means of the field ‘node_type’, which is set to ‘centroid’ in this case. The ‘node_type’ field is an optinal field listed in the GMNS node table specification.

You can find the GMNS specification here.
