GTFS
The General Transit Feed Specification: the schedule format that puts a city's buses into every journey planner. Adopting it is the cheapest interoperability decision a transit agency can make, and the one most often left half-done.
How this list is decided. Membership is not a field an editor set: it is every published entry whose own text names GTFS, matched at build time, with the sentence printed under each row so you can judge the match yourself. 27 entries in 24 cities. For what the term means rather than who uses it, see GTFS (General Transit Feed Specification) in the glossary.
✔ Every published entry is checked against the public sources it cites before publication.

A second campaign from 19 July to late September 2017, run with the consultancy Transitec, the Jungle Bus team, the French development agency AFD and Ghana's OpenStreetMap community, sent six contributors into the field to record stops and routes directly into OpenStreetMap; a GTFS feed is generated from that data w…
No public GTFS or developer feed for Ankara could be found.
In 2024 the bus and metro operators published their schedules as GTFS on the state transport directorate's data hub, the first release of BMTC data in a global open standard.
TransMilenio S.A., the district company, is also the managing entity for Bogotá's wider SITP bus network and TransMiCable, and it publishes static and real-time GTFS feeds with no licence attached.
The most detailed technical account found: GTFS as the data standard, the CSO housed in a converted warehouse in the TCB garage near the Palácio do Buriti at a cost of about R$9 million, and the two-packets-every-30-seconds figure used in the snippet.
Two round-the-clock control rooms track train positions alongside traction power, ventilation and pumping, and SBASE publishes static GTFS plus a real-time feed that Google and Moovit consume.
The measurement layer the city actually owns is narrow: camera enforcement of the exclusive lanes, and an open transport data platform publishing GTFS and real-time feeds.
Nothing measurable comes back out of it either: neither operator publishes ridership or a schedule feed, circulating daily-ridership claims run from 3 million to 5 million with no reconciliation, and the only machine-readable Cairo Metro GTFS is a third-party estimate released by Transport for Cairo in 2016 under a …
Riders now meet the predictions largely inside other people's apps: the agency publishes Bus Tracker, Train Tracker, alert and GTFS-Realtime feeds, each behind a free registered key.
In July 2026 the Jalisco transport ministry completed the first stage of digitising the state's public transport network, publishing more than 275 routes to the international GTFS standard so that routes, stops and timetables can be read in Google Maps and comparable applications from any phone or computer.
Current, actively maintained routing/GTFS API documentation confirming the platform is still live.
Every bus now reports its position through a public GTFS-realtime feed powering the RideMETRO app and SMS next-bus lookup.

İETT also publishes GTFS schedules and real-time vehicle web services on İBB's open data portal, letting third-party apps reuse the same feed.
Carris, Lisbon's municipal bus and tram operator, has published a static GTFS schedule feed since 2020 and tracks its fleet by GPS through the XTraN Passenger platform, contracted from Tecmic for about €3.4M between 2019 and 2020 and migrated through 2022.
Those buses report their position by GPS into a public GTFS-Realtime feed, and a control centre opened in the Escandon district in 2023 monitors the network as cameras are fitted to buses and stations.
Static GTFS is a public download, while GTFS-realtime for buses, Metrorail and Metromover is served through Swiftly and requires requesting access — the real-time layer is published but gated.
Researchers from MIT, Columbia and the University of Nairobi rode roughly 130 matatu routes with GPS-equipped phones, then converted the data into a modified GTFS loose enough for a system with no calendars, no service frequencies and no operating schedules.
It is the older sibling of Digital Matatus, and the difference is the object: Digital Matatus mapped a transport network into GTFS from 2012 and was university-led, while this mapped a place, and residents did the surveying.
Alongside the real-time services Nantes Métropole publishes GTFS, NeTEx stops and NeTEx offer files, plus GBFS feeds for four separate shared-mobility operators.
Delhi's transport department has published its bus network as open data since November 2018 — GTFS timetables, stop coordinates and route maps, plus a GTFS-Realtime feed of vehicle positions refreshed every ten seconds; the government called it the first such portal in India.
The oldest datasets were created in April 2014 and the newest in June 2023; the live transit feeds have since moved to the national access point transport.data.gouv.fr, where the Métropole has published GTFS, NeTEx, SIRI and real-time GTFS-RT vehicle positions since June 2025.
Every bus carries GPS and cameras feeding an operational control centre at Terminal Alvorada, and the city publishes a real-time BRT vehicle-position API and monthly GTFS on data.rio.
Roma Servizi per la Mobilità, the mobility agency of Roma Capitale, runs the "Muoversi a Roma" traffic-and-transit information portal and app (launched 2014) and publishes the city's public-transport data as open GTFS and GTFS-realtime feeds.
Operator page for the AVM fleet-tracking system: roughly 300 electronic bus-stop displays, GTFS and real-time feeds.
Carries GTFS, GTFS-Realtime (Trip Updates, Vehicle Positions, Service Alerts) and SIRI/NeTEx APIs, lists SFMTA among operators, requires a registered API token, defaults to '60 requests per 3600 seconds', and applies its own data agreement on top of any operator terms.
Transport for NSW's Open Data Hub has published live GTFS-realtime feeds — vehicle positions, trip updates and alerts — for Sydney's trains, buses, ferries and light rail since 2016, with feeds refreshing about every 15 seconds under a CC BY 4.0 licence.
Vilnius publishes municipal datasets — including public transport GTFS feeds — on one open CKAN portal, letting developers and residents build on official city data directly.
