New: GTFS-Realtime Service Alerts authoring (Agency plan)

You can now author GTFS-Realtime Service Alerts directly in GTFS·X and serve them at a stable, spec-compliant URL that Google, Apple, and transit apps can consume.

What's new

• A new Service Alerts section (under Operations in the left rail) on any cloud feed.
• Post detours, delays, stop closures, and system-wide notices with Cause / Effect / Severity, one or more active time windows, and affected entities (whole feed, specific routes, or stops).
• Alerts are decoupled from publishing — post or expire an alert instantly, without republishing your GTFS schedule.
• Served live at feeds.gtfsx.com/<your-slug>/alerts.pb (protobuf) and /alerts.json — a GTFS-RT FeedMessage v2.0 carrying only currently-active alerts, with a short cache.
• The alerts feed is automatically advertised in your feed_info.json so downstream consumers discover it.

Availability — Service Alerts authoring is part of the Agency plan (and Enterprise). The served alerts feeds are public; only authoring is gated.

v1 is single-language for now (multi-language is on the roadmap). Trip Updates and Vehicle Positions remain out of scope — they need live AVL.

Try it: open a feed → Operations → Service Alerts → New alert. Feedback welcome in this thread!
