This looks a bit complicacted:

We could just add all of them and hope deduplication is fast enough

vkrause commented 3 months ago

Right, that's the only option I see as well, similar to the situation in DE.

Which kind of de-duplication is currently in place? Otherwise there are also existing tools to combine GTFS-RT feeds, which might be worth a look: https://github.com/mbta/concentrate

We don't have any Transitous-specific deduplication so far, only what's already in MOTIS.

With the latest release v0.12.5 it should be fast enough. At least before it was approx 50% of the import time, now it's gone from the profiler. So my hope would be that this approach would work on a larger scale (e.g. also in Germany).

Are there any blockers in MOTIS to try this? If I remember correctly, I read somewhere that Sweden uses the alternative method to identify trips via route_id, direction, etc. (maybe I'm wrong.. can't find it anymore) but I tried to check with the first feed from https://www.trafiklab.se/api/ and didn't get any unsupported_no_trip_id in the statistics.
