Public Transport evaluation

[kiselev-dv]

GTFS

• Evaluate GTFS availability
• GTFS data deduplication
  • How often trips vary for the route
  • Geometry artifacts for trip/route geometry
    • are stops always within some distance form route geometry
    • do we have geometry tails for route
  • different transit aggregators giving the same route but with different details

OSM data related to GTFS

OSM taginfo for GTFS: https://taginfo.openstreetmap.org/search?q=gtfs#keys

• Check how well data from OSM https://taginfo.openstreetmap.org/keys/gtfs_id#map matches with GTFS

PT Routing algorithms / libraries

GTFS aggregators

• transitland

[kiselev-dv]

Singapour

• Use their own format JSON/XML
• Data available at https://datamall.lta.gov.sg/content/datamall/en/dynamic-data.html#Public%20Transport
• OSM data use ref and route_ref on stops

Canada / New Brunswick

• GTFS feed: https://open.moncton.ca/documents/moncton::transit-files-gtfs/about
• OSM data use gtfs_id on stops, ids are AlphaNum

Canada / Toronto

• GTFS: https://www.transit.land/places/Canada/Ontario/Toronto
• Different providers
• OSM data: Some stops have ref matching gtfs code, also there are ref:<transit operator>

there's also this list on the OSM wiki: https://wiki.openstreetmap.org/wiki/List_of_GTFS_feeds
might be good to copy what we learn on this thread to it, for future people :)

Thank you, I agree and I will update the osm wiki.
