Auckland opens its live bus, train and ferry feed to any registered developer. The auditor found the part riders need most, the disruption alerts, is still entered by hand.
what does this mean?
The strongest source is an independent non-academic evaluation: an audit office, a government or EU review, or an NGO. It grades who did the looking — not how well the project went. All four grades →Part of 1001 Smart Cities — 1,216 documented projects · 🏙️ 9 more in Auckland · 📊 Open data guide · 📡 Data & IoT projects
Auckland Transport publishes its timetables as a downloadable GTFS file and its vehicle positions, trip updates and service alerts as a GTFS Realtime feed open to any developer who registers for free. A beta API opened before a May 2014 hackathon; real-time GTFS data reached registered users only in November 2015, after a developer used an official information request to ask when the API would stop serving mocked data. AT's own AT Mobile app uses the same APIs. AT says the data it releases is licensed under Creative Commons Attribution 4.0, but the developer portal's terms say their licence does not apply to the datasets themselves. In May 2025 the Auditor-General found that AT's disruption alerts are entered manually and that ferry tracking is not always accurate.
📊 Impact
No source measures an effect of publishing the feeds themselves. What the Auditor-General recorded in May 2025 is what the tracking data changed inside Auckland Transport: it uses the information to measure the reliability and punctuality of every mode, in 2023/24 it introduced a reliability measure that considers services that were cancelled or did not start their route within a reasonable time, and it has strengthened reliability and punctuality expectations in its operator contracts in line with improvements in its ability to track their services. Outside AT, a University of Auckland statistician described in August 2022 bots that report punctuality, cancellations and headways for Auckland buses from the AT GTFS feed, and warned that some outliers appear to be errors, such as buses that start updating their position long before a trip or keep updating long after it.
🎓 Lesson
An open feed answers whether the data exist, not whether they are complete. Bus positions in Auckland come from automatic vehicle location devices, but the auditor found that the information a passenger most needs at a stop, that a trip is disrupted, still depends on operators notifying AT and on staff entering it by hand, with limited or no information about unplanned disruptions outside business hours. The paperwork matters too: an outside count of cancellations built on the feed is only as complete as the alerts AT types in, and a developer reading the API terms finds a licence for the portal's pages, not for the data.
