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-8b48cb1da0f87dea quantitative
began in 2012 under the Arriyadh Development Authority
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The integrator's case study dates the Riyadh Advanced Traffic Control System programme from 2012, with RCRC (the ADA's successor) as client, and describes it as current.
Caveat
Vendor-side dating; the operator's own pages are inaccessible to automated verification.

Sources carrying this claim

  1. KLD Engineering — Riyadh ATCS case study
Claim 2 clm-76cc73a394c9ab5e quantitative
in February 2015 TransCore won a $100 million contract to deploy its TransSuite traffic-management system with adaptive control at 350 of the city's busiest intersections
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
TransCore's press release of February 24, 2015 announces the $100 million ADA contract for TransSuite with adaptive control at 350 of Riyadh's busiest intersections.
Caveat
Vendor announcement; the figure is the contract value, not an audited spend.

Sources carrying this claim

  1. TransCore — Riyadh traffic management contract
Claim 3 clm-55593c69b22afa69 quantitative
1,400 cameras on city entrances, ring roads and main junctions that read licence plates and flag vehicles wanted by security authorities
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
RCRC's own announcement describes 1,400 cameras covering Riyadh's entrances, ring roads, squares, axes, intersections and main roundabouts, able to read licence plates and identify vehicles reported by security authorities.
Caveat
Operator self-description; the RCRC site rejects automated fetches and the wording was verified through search excerpts.

Sources carrying this claim

  1. RCRC — ADA deploys an advanced traffic management system
Claim 4 clm-6494aa92cf29514a descriptive
distinct from Saher, the Ministry of Interior's national enforcement cameras
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Press coverage documents Saher as the national automated enforcement programme launched in 2010 under the Ministry of Interior — a separate system from the city's traffic-signal network.
Caveat
No claim-specific caveat recorded

Sources carrying this claim

  1. Arab News — automated systems against congestion
Claim 5 clm-3d090f4c7d1d4143 quantitative
The 84 junctions of the bus rapid transit corridors were later wired into the same control system for the 2023 bus launch
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
SWARCO's project page records the supply, integration and testing of 84 BRT intersections connected to the RCRC Advanced Traffic Control System as part of the public transport megaproject.
Caveat
Vendor page, bot-walled to automated fetches; verified via search excerpts.

Sources carrying this claim

  1. SWARCO — BRT technology upgrade of Riyadh's bus rapid transit intersections
Claim 6 clm-9aa322762c5ceddf quantitative
losing an average of 52 hours a year to congestion as of early 2025
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport

Claim 7 clm-65ff9bd78d33e812 quantitative
a 28% drop in journey times on Al Takhassusi Road after signal synchronisation
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
RCRC's announcement states journey time dropped by 28% on Al Takhassusi Road after the system optimised and synchronised signals.
Caveat
The operator's own before/after figure; no independent evaluation has been published.

Sources carrying this claim

  1. RCRC — ADA deploys an advanced traffic management system
Claim 8 clm-bbb1d495a0e475a4 quantitative
over 90% of equipped intersections improved or performed comparably

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.
