Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-be0544b9d92b3686 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
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The November 2018 launch report gives the date, the GTFS format and the ten-second GPS refresh; Swarajya in 2026 restates it — 'In November 2018, Delhi became the first Indian city to publish its transit data in an open, machine-readable format' — and the portal itself lists the static GTFS files and the VehiclePositions endpoint.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Business Standard / PTI — Delhi government launches portal for spotting location of cluster buses (23 Nov 2018)
  2. Swarajya — Delhi has the buses, the data, and the apps. Why can't you still find your bus? (10 Mar 2026)
  3. Open Transit Data Delhi — developer documentation
Claim 2 clm-8f85e2f399c04b21 quantitative
Built by IIIT-Delhi with DIMTS and DTC, it began as a beta covering roughly 1,700 cluster buses

  1. Business Standard / PTI — Delhi government launches portal for spotting location of cluster buses (23 Nov 2018)
Claim 3 clm-75c4d8bd5881e256 quantitative
now feeds the city's own One Delhi app, which tracks more than 7,300 DTC and cluster buses on over 500 routes
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
ThePrint, 2 November 2022: the revamped One Delhi app 'comes with several new features including live tracking of over 7,300 DTC and cluster buses, searching more than 500 bus routes and locating over 2,200 Electric Vehicle (EV) chargers among others.'
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. ThePrint — Revamped version of 'One Delhi' app launched (2 Nov 2022)
Claim 4 clm-5e95d0f1f5a2ed12 descriptive
Real-time access requires a registered API key

Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The portal documentation: 'Authorised users can request for real-time data at /api/realtime/VehiclePositions.pb?key=YOUR_PRIVATE_KEY'.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Open Transit Data Delhi — developer documentation
Claim 5 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
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Swarajya, 10 March 2026: 'Bus GPS units go offline. Routes change without the static data being updated. DEVI buses stopping informally generate no location signal a passenger at a notional stop can use.'
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Swarajya — Delhi has the buses, the data, and the apps. Why can't you still find your bus? (10 Mar 2026)
Claim 6 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

What the mapping says
'By 2022, more than 10,000 entities had downloaded the static data, and over 50 organisations, including Google Maps, MapMyIndia, TCS Research, and researchers at Harvard, were consuming the live feed.'
Caveat
Downloads and feed consumers measure uptake by developers, not what a passenger can see at a stop.

Claim 7 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'

What the mapping says
The portal's Warnings section, verbatim: 'The arrival and departure times of buses as mentioned in stop_times.txt is not accurate and is a rough estimate generated by assuming a constant speed of travel.'

Claim 8 clm-2e457799bc28d3c6 quantitative
the March 2026 report follows a passenger who establishes which stop serves her route by asking strangers
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The report opens with a passenger who walks to one stand, waits ten minutes, learns from a fellow passenger that her buses do not stop there, walks to another, and confirms it 'with two or three strangers before crossing over'. At the right stop there is no shelter.

Currency 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.
