About GTFS data imports into OSM

We should probably warn public transport enthusiasts against the idea to blindly import GTFS feeds into OSM. Common sense and human review should always prevail.

For instance, the public transport company operating in my area sometimes removes stops that have no service within the current 14-day period or adds temporary stops to GTFS data; it also adds some non-existing stops that are used exclusively for timetabling purposes. In addition to that, stops can be relocated or renamed and sometimes it will take months before the transit authority updates their files to the real situation.

Every now and then, we see new mappers changing or removing valid OSM data because they do not realize how GTFS data is produced, and want OSM to match GTFS data, regardless of ground truth or existing standards, such as mapping normal itineraries and ignoring short-term service changes.
