Support ssim format for flights? #652

Closed Altonss closed 5 days ago

Altonss commented 5 days ago

Data for airlines doesn't seem to available very often as gtfs formats. I see that the ssim format seems to be used quite often, would it make sense to support it in motis? (see for example https://github.com/planarnetwork/ssim2gtfs to convert into gtfs)

Sounds interesting. Thank you! Is there any disadvantage to use the tool you linked and let MOTIS consume GTFS?

Good point, I don't know actually :) Projects using Motis (e.g. Transitous), could indeed just have a GTFS converter for those types of feeds. The advantage of having it directly integrated in Motis, is that all projects using Motis would directly benefit from it and not have to reimplement this functionality.

Since transitous (and most other MOTIS users) has a preprocessing pipeline anyway, using ssim2gtfs seems like the easiest solution for now. Let me know if any problems come up with this approach. Closing this for now. Reopen if any issues with conversions pop up.

Asking from the Transitous perspective, are you aware of any publicly available SSIM datasets?

A quick search gave me this for example: https://transport.data.gouv.fr/datasets?locale=en&type=air-transport
