quantitative
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
clm-8f85e2f399c04b21
quantitative
Built by IIIT-Delhi with DIMTS and DTC, it began as a beta covering roughly 1,700 cluster buses
clm-c5e4a8a59b4b00b1
quantitative
now feeds Google Maps and the city's own One Delhi app, which tracks more than 7,300 DTC and cluster buses on over 500 routes

descriptive
Real-time access requires a registered API key
clm-d77e8880352ad9eb
quantitative
Reporting in March 2026 found the data patchy on the ground: GPS units drop offline, route changes are not always reflected in the static files, and no bus stop shows live arrivals
clm-3112bcceb0316905
quantitative
By 2022 more than 10,000 entities had downloaded the static data and over 50 organisations — including Google Maps, MapMyIndia and TCS Research — were consuming the live feed, as reported by Swarajya in March 2026
clm-67595971dba94c7d
descriptive
its own documentation warns that the timetable it ships 'is not accurate and is a rough estimate generated by assuming a constant speed of travel'
clm-2e457799bc28d3c6
quantitative
the March 2026 report follows a passenger who establishes which stop serves her route by asking strangers
This layer records what is known about each source, what is still missing, and the exact snapshot this page is rendering. A missing date, archive or hash stays visible as missing.
Awaiting operator and domain-expert review; publication of this revision implies neither.
Erratum on this revision's envelope. The snapshot, its hash and its permanent link are untouched.

src-f45fa40ff45c7279Operator portal, fetched 2026-07-26: lists the GTFS static files and the GTFS-Realtime VehiclePositions endpoint (private key required); names DMRC, DTC, DIMTS, the Transport Department and IIIT-Delhi. States plainly that stop_times arrival times are a rough estimate assuming constant speed.
src-db4f82f54b1ef12aLaunch report: date, ~1,700 cluster buses in the beta, GPS every 10 seconds, GTFS, developed by IIIT-Delhi, and the government's claim that Delhi is India's first city to open bus transit data.
src-58d05461e79cbd45Source for the consumer layer: live tracking of 7,300+ DTC and cluster buses, 500+ searchable routes, developed with IIIT-Delhi; app first launched in 2019 and rebuilt in 2022. The article now renders only as a JavaScript shell to an automated client, so no publication date is recorded here.
src-3f7506e79415a1feCurrency check and counterweight: confirms the portal and app are running in 2026, carries the 10,000 static-data downloads / 50+ live-feed consumers figure for 2022, and documents the gaps — offline GPS units, stale static data after route changes, buses missing from the system, inaccurate ETAs, no real-time displays at stops.
