Refresh live trip data after route document changes
Structural edits can signal a new plan, so get current trip data at that moment.
Trigger
Document Structure Changed
Triggers when a Google Doc's structure changes (headers/footers added/removed, tables/images count changes). This trigger monitors a specific document for structural changes like: - Headers added or removed - Footers added or removed - Tables added or removed - Images (inline objects) added or removed - Positioned objects added or removed - Footnotes added or removed
Action
Get GTFS-RT Trip Updates
Tool to fetch real-time trip updates in gtfs-realtime format. use when you need the latest live trip information as raw protobuf.
Why this helps
A route document can change materially through tables or images without an obvious text update.
- Detects meaningful layout changes
- Fetches current raw trip updates
- Creates a prompt for route validation
Setup
Build it in a few focused steps.
- 1Connect Google Docs and Bart in Notis once.
- 2Create an automation named Structural route update monitor.
- 3Ask Notis to inspect the changed document for route context and retrieve current GTFS-RT trip updates.
- 4Pick Document Structure Changed, choose a report channel, and test with a structural edit.
