Seattle region: Sound Transit routes, stops and schedules, as a static GTFS zip.
Good for
Verdict
A regional timetable feed for Seattle-area routing, alongside king-county-metro-gtfs. Licence: Custom, listed under the express-permission exception. The Transit Data Terms of Use, which govern the documented GTFS feed, say "You are free to use the Data in any way you choose with the following exceptions:" The exceptions cover malicious intent, intent to commit a crime and public distribution of rider or transit-worker personal information; the data terms do not restrict automated retrieval. The general website Terms of Use separately bar users who "Use any robot, spider or other automatic device, process or means to access the Website for any purpose, including monitoring or copying any of the material on the Website." That website clause is quoted for completeness; the specific Transit Data Terms govern this documented feed, so use the GTFS download, not the website pages. Rate limits: Not stated. Signal Lab links only.
