Review & Discussion of Web-Based SUMO Tools for Demand and Network Modification

Challenges and talking points

Networks:

• How to edit networks (connections, TLS) without calling netconvert?

  • Reason: efficiency or stability of parts of the network, that were not touched by the patch - possibly a bug in netconvert?
  • WASM wrapper for netedit to bring it to the frontend?
  • Netconvert conversion from OSM is a moving target and constantly adapts to fix bugs (see sources and sumo docs about OSM interpretation of ways)
    • see: https://sumo.dlr.de/docs/Networks/Import/OpenStreetMap.html#netconvert_details

• Network versioning control incl. changes from OSM and manual edits?

  • Davide: initial work on patching solution based on netdiffs
  • Jakob E.: recommends to work with netconvert (do not work with file-based patching)
  • Tool for map matching could be usable to convert patches from one OSM base map to another version of the OSM map
  • Edit in OSM directly (fix it upstream?)
  • Feature request by Moritz S.: preserve original OSM node id in the edge (–> Jakob E.)
    • see https://github.com/eclipse-sumo/sumo/issues/16937

• Reading networks from geoparquet format? (Alternative to geojson)

  • as input from overture maps
  • as output for geojson frontends (leaflet?)
  • Observation: parquet does not save a significant amount of disk space - but that is not the main goal; that is the reading time!

For next time:

• User defined rerouters with preferred alternative route
  • Tickets: https://github.com/eclipse-sumo/sumo/issues/7197 and https://github.com/eclipse-sumo/sumo/issues/3320
• Replay vehicle trajectories from meso simulation
• VISUM / VISSIM Import?
• Repairing demand after scenario network modification?
• Potential for common front-end components?

Any other Business

• None
