Transit Analytics Copilot
Stop wrestling with GTFS. Start asking it questions.
Ask your schedule a question, get a real answer — in seconds. No spreadsheets, no pivot tables, no waiting.
15 routes have AM peak headways exceeding 30 minutes. The worst:
| Route | Headway |
|---|---|
| 963 | 58 min |
| 955 | 56 min |
| 833 | 53 min |
| 874 | 48 min |
Data sources:
query_gtfsYou shouldn't need a data scientist to understand your own schedule.
Transit planners spend hours filtering stop_times in Excel, piecing together headways, and running one-off scripts just to answer basic questions for leadership or the public.
Marga changes the workflow. If you can type a question, you can analyze your entire network.
