GTFS viewer

The GTFS viewer online loads a GTFS feed from a URL or file, parses core files, and exposes a structured data model that can be queried by date, route, and stop. It does not provide live transit data or realtime updates; it focuses on static feed inspection and analysis.\n\nConceptually, it ingests the feed, builds in-memory mappings between stops, routes, and trips, and derives timetables. Users can filter by date, route, or stop to see sequences of departures, headways, and service days. It supports offline analysis and API-ready outputs.\n\nWho benefits include transit agencies, consultants, researchers, and developers who need a fast, deterministic GTFS view without installing tooling. Unique value lies in offline accessibility, deterministic parsing, and structured outputs suitable for analytics pipelines. Core features include feed ingestion from URL or file, validation, date-based filtering, route/stop probes, and exportable JSON summaries. Typical use cases include QA checks, onboarding new feeds, comparing schedules across feeds, and preparing data for analytics pipelines.\n\nUse cases include data validation, schedule auditing, and cross-feed comparisons. Outputs are designed to feed downstream analytics, dashboards, or custom APIs, enabling rapid iteration during data onboarding and transit planning projects.
