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-8736dc43de49b901 quantitative

travel times improved 29% for bus riders and 20% for motorists, plus ~86,000 tonnes CO2 avoided per year

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: No support note recorded
Caveat: The 2011 evaluation reports improvements in travel time, not in speed, and no independent re-evaluation has updated it since; current ridership of roughly 1 million a day is an operator figure.

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.
