Steps
Confirm the feed version: GTFS-Flex was merged directly into core GTFS in 2024, so current authoritative reference lives under the google/transit repo and gtfs.org, not the deprecated standalone MobilityData/gtfs-flex repo
Look for flex-specific files such as booking_rules.txt and location_groups.txt/locations.geojson alongside standard GTFS files
Identify stop_times.txt rows referencing flexible service via start_pickup_drop_off_window/end_pickup_drop_off_window instead of fixed times
Read booking_rules.txt to determine how far in advance a rider must request a trip and by what mechanism
Note that GTFS-Flex is static-only — it models business rules for demand-responsive service, not live vehicle location or real-time booking availability
Known gotchas
The standalone MobilityData/gtfs-flex GitHub repo is explicitly marked deprecated/no-longer-up-to-date; don't cite it as the current spec source
Flex data describes eligibility/booking rules, not real-time dispatch — pair it with a separate booking system for actual reservations
