1. Download Czech Republic (.osm): https://download.geofabrik.de/europe/czech-republic.html

2. Use osmium-tool to extract Prague: https://osmcode.org/osmium-tool/manual.html#the-osmium-command

   1. Polygons describing Prague (.geojson) - 57 districts: https://www.geoportalpraha.cz/en/data/opendata/E9E20135-18B3-4163-B516-45613956B856

   2. Join the districts into one polygon: ./dissolve-polygon.py MAP_MESTSKECASTI_P.json prague-polygon.json

   3. Run: osmium extract -p prague-polygon.json czech-republic-latest.osm.pbf -o prague.osm.pbf

   4. Optionally convert to osm: osmium cat prague.osm.pbf -o prague.osm

3. Optional: Create a multimodal network (roads, pt, rails, ...) __https://github.com/matsim-org/pt2matsim/wiki/Creating-a-multimodal-network-(Osm2MultimodalNetwork)

OpenStreetMaps

Allows to export only a small area!

1. Export OSM data (map.osm)

2. Compress using some tool to .osm.pbf (e. g. osmium-tool): https://osmcode.org/osmium-tool/

3. Use SupersonicOsmNetworkReader to change data to MATSim XML (OsmNetworkReader is deprecated)

4. Run NetworkSimplifier from MATSim - improves simulation performance, introduces artifacts

5. Run NetworkCleaner from MATSim

Cycle Data in OSM

Refer to: https://2018.stateofthemap.org/slides/A35-Using_OpenStreetMap_to_model_bicycle_traffic_in_an_agent-based_transport_simulation.pdf

Bikes in MATSim: https://github.com/matsim-org/pt2matsim/issues/137

• Main road with a bicycle lane

  • highway=? and cycleway=lane

• Bicycle lane on the sidewalk

  • highway=? and cycleway=track

• A bicycle track away from roads

  • highway=cycleway

OSM Tags in MATSim OsmNetworkReader

To process the OSM file into a MATSim network correctly, the following tags must be used:
