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-d8c36da283e9be95 quantitative

Almost 80% of motorised trips in Accra are made on trotros, 10-to-19-seat minibuses run by private operators along fixed lines and stops

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The project record states that in Accra almost 80 per cent of motorised trips use trotro lines, and describes the vehicles as 10 to 19-seater minibuses operated by private operators organised along stops and fixed lines.
Caveat: No claim-specific caveat recorded

Claim 2 clm-8c694ab0a99f0eb3 quantitative

In 2015 Ghana gave four Accra municipalities their own transport departments, and Concordia University students identified the roughly 300 lines that make up the network and assessed the level of service on 60 of them

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The record states that in 2015 Ghana's government provided Departments of Transport in four municipalities of Accra, and that in phases 1 and 2 Concordia University students identified the routes and the 300 lines composing the network and then qualified the level of service for 60 of those lines.

Claim 3 clm-3bcd44bee7c711b2 quantitative

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 with OSM2GTFS

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The project page states AccraMobile3 was launched in July 2017 to map all Accra's trotro lines into OpenStreetMap for the Department of Transport, names the Jungle Bus team, AFD, Transitec and the local OSM community, dates field collection from 19 July to late September, records that bus stops were collected in the field by six OSM contributors, and states a GTFS is created from the data with OSM2GTFS.

Claim 4 clm-8db001e4d9f6d255 descriptive

The network is in OpenStreetMap, where Ghana's mapping community still holds it, and the derived GTFS is published in the World Bank's data catalogue and remains downloadable

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The project page records the data as living directly in OpenStreetMap with the local community as a partner; the World Bank catalogue publishes the derived GTFS, and the project repository holds the project data.

Claim 5 clm-ae3f2cb5c45e298b descriptive

it is the basis of the Trotro App, a passenger app maintained by the Trufi Association

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The Trufi Association lists the Trotro App for Accra as one of its projects, an app for navigating Accra by public transport.
Caveat: No claim-specific caveat recorded

Claim 6 clm-2f3e77615495db1c quantitative

the feed served today carries a service calendar that ran out on 31 January 2020, and no route has been re-surveyed since 2017

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The feed registry entry shows the served feed's service calendar ending on 31 January 2020; the project page documents the 2017 campaign as the field survey and records no later one.
Caveat: No claim-specific caveat recorded

Claim 7 clm-4568a69cc229a4bf descriptive

the data outlived its funder because it was put somewhere anyone can edit, and an app still runs on it

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The project deliberately placed the network in OpenStreetMap rather than in an agency system, and the Trufi Association's passenger app is built on it.
Caveat: No claim-specific caveat recorded

Source dossiers and revision state

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.

unreviewed Revision 2026-08-27-claims-and-sources effective 2026-08-01 · created 2026-08-27

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.

createdAt previously read 2026-09-03T17:00:00Z. The batching script that produced this revision advanced createdAt into the future to satisfy the strictly-increasing order the validator requires per entity. The value never recorded a real event; the corrected value is the moment the revision provably existed in the repository. Corrected to 2026-08-27T04:13:17Z on 2026-08-27; evidence: first appears in commit 914bd7a36a, committed 2026-08-27T04:13:17Z.

Known limits of this passport

Publisher names and source languages have not yet been classified; domains are recorded without guessing.
Existing source notes are descriptive locators, not page- or paragraph-exact citations.
A missing archive, publication date or content hash is shown as null rather than inferred.
The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
