Since 2018 the City of Paris and the Paris2Connect consortium have run a shared 'digital infrastructure' testbed along a 3.5 km route in the Paris Rive Gauche district (13th arrondissement): a private 4G/5G-plus-WiFi network and nine 'connected poles' carrying sensors. A digital-twin layer (built by Siradel) fuses the city's geospatial and regulatory data with the poles' real-time feeds to model traffic, environmental health and disruption scenarios. The City co-funded roughly 25% of the budget under the EU InDiD programme (to 2023); this is a district-scale pilot, not a citywide Paris digital twin.

Claim 1 clm-eef09f57b0982bf9 quantitative
Since 2018 the City of Paris and the Paris2Connect consortium have run a shared 'digital infrastructure' testbed
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Smart City Mag states the project was 'Lance en 2018, dans le cadre de l'appel a projets "quartier d'innovation urbaine" (QIU) pour Paris Rive Gauche (13e arrondissement)' (launched in 2018 under the 'urban innovation district' call for the Paris Rive Gauche district). Paris2Connect's own consortium page states: 'Since 2018, the Ville de Paris and the Paris2Connect consortium have been testing an urban and connected infrastructure...'. The RATP newsroom article (indexed by search engines; direct fetch returned HTTP 403 on every attempt) likewise frames the City of Paris and the consortium jointly. Caveat: the three readable sources document distinct stages of the pilot (a 2018 launch, a 'first building block' deployment around 2019, and a Feb-2021 'operational phase') rather than proof of one unbroken run through to today.
Caveat
The sources confirm the 2018 launch and the pilot's 2019-2021 build-out, but none of the four listed sources is dated later than about 2021-2023, so none confirms the testbed was still running as of 2026, the year this entry says it was last verified.

Claim 2 clm-3756c978f7305683 quantitative
along a 3.5 km route in the Paris Rive Gauche district
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Smart City Mag quotes the consortium's Laurent Benet: 'Courant janvier, nous allons installer nos premiers "smart poles"... sur un parcours de 3,5 km entre les gares d'Austerlitz, Lyon et Bercy' (a 3.5 km route between Austerlitz, Lyon and Bercy stations) and identifies the site as the Paris Rive Gauche district. The RATP newsroom article (search-indexed; direct fetch returned HTTP 403) corroborates the same 3.5 km route and Paris Rive Gauche framing, connecting Bercy, Lyon and Austerlitz stations.

Claim 3 clm-c39cf31387fa2fba quantitative
a private 4G/5G-plus-WiFi network
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The RATP newsroom article, as reflected in search-engine indexing tied to this exact URL and title, describes the testbed as offering 'a private 4G network (soon 5G) and a WiFi network'. This is the only one of the four listed sources that mentions network technology at all — Smart City Mag, which was fetched directly, does not specify it. [find: null — RATP-Seite blockt automatisierte Abrufe (HTTP 403 bei jedem Versuch); der Netzwerktechnik-Satz ist nur ueber Suchindex-Text bekannt, nicht direkt gegen die Live-Seite verifiziert.]
Caveat
Could not be confirmed by directly fetching the RATP page (HTTP 403 on every attempt); this rests on search-engine index text matched unambiguously to this article's URL and title, not on an independently verified read of the live page.

Claim 4 clm-f9704c4aef821bbc descriptive
nine 'connected poles' carrying sensors
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Smart City Mag states 'En 2021, neuf "smart poles" vont etre deployes sur la zone de test' (nine 'smart poles' were to be deployed on the test zone in 2021) — a 2021 target at the time of writing, not a confirmed count as of any later date. The RATP newsroom article (search-indexed; direct fetch 403) separately describes 'nine connected masts hosting a set of sensors' along the same 3.5 km route.
Caveat
The number nine is the target for 2021 in the Smart City Mag article (published February 2021); no source dated after 2021 was available to confirm the count is still nine, or that all nine poles remain functional, as of the entry's 2026 verification date.

Claim 5 clm-6ffb44573f786ead descriptive
A digital-twin layer (built by Siradel)
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The Paris2Connect consortium's own digital-twin page names Siradel among the partners credited specifically on that page (alongside ATC France, Aximum, Nokia, RATP group, Signify and Meersens), but the fetched text contains no explicit sentence such as 'built by Siradel' or 'Siradel developed this layer'. The attribution that Siradel specifically built the digital-twin layer (rather than just being a general consortium member) is an inference from Siradel's placement on this specific page, reinforced by outside reporting (not one of the entry's four sources) that credits 'Siradel and Meersens' with designing the Paris2Connect digital twin. [find: null — Siradel erscheint unter den Partner-Hashtags der Seite, aber ein eindeutig zitierbarer Wortlaut liess sich nicht sicher genug feststellen.]
Caveat
The source credits Siradel as a partner named on the digital-twin page, not as an explicit statement that Siradel built the layer; the 'built by Siradel' attribution is inferred rather than quoted.

Claim 6 clm-662db622d36dac1c descriptive
fuses the city's geospatial and regulatory data with the poles' real-time feeds
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The consortium's digital-twin page states directly: 'The digital twin integrates regulatory, geospatial, environmental and usage data alongside real-time sensor information.' This confirms the fusion of the city's geospatial/regulatory data with the poles' real-time sensor feeds; the page also names environmental and usage data as additional inputs, which the claim does not need to cover.
Caveat
No claim-specific caveat recorded

Claim 7 clm-d3db3f0873c5eeb1 descriptive
to model traffic, environmental health and disruption scenarios
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The digital-twin page states the replica is 'a real strategic tool for managing urban planning and development, simulating day-to-day management, or playing out disruption scenarios' (confirms 'disruption scenarios' almost verbatim) and separately says Paris2Connect 'offers the City of Paris a relevant tool for rethinking the use of roads and developing sustainable mobility', plus that the infrastructure 'generates local data beneficial for enhancing traffic models' (confirms 'traffic'). 'Environmental health' is the weakest of the three: the page references France's 4th National Environmental Health Plan as policy context and lists 'environmental...data' among the twin's inputs, but never states that the twin itself models environmental-health outcomes or scenarios.
Caveat
'Traffic' and 'disruption scenarios' are supported close to verbatim ('enhancing traffic models', 'playing out disruption scenarios'). 'Environmental health' is weaker: the source ties environmental data ingestion to France's National Environmental Health Plan as context and to improving traffic models, but does not say the twin models environmental-health scenarios as such — the snippet's phrasing simplifies a narrower claim.

Claim 8 clm-af6ca318dbca45b2 quantitative
The City co-funded roughly 25% of the budget
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Could not be confirmed by directly reading this source: every fetch attempt on the Usine Digitale URL returned HTTP 403 (a documented pattern for this and other French trade-press domains in this project). The 25% City-of-Paris co-financing figure, against a roughly EUR 3.5m total budget, is corroborated by several independent secondary outlets covering the same project in the same period (none of which are among this entry's four listed sources, so they cannot be cited here directly). The entry's own note for this source ('use to help confirm 2023-2024 status') suggests the original editor drew this figure from this article, but that could not be independently verified in this review. [find: null — Usine Digitale blockt automatisierte Abrufe (HTTP 403 bei jedem Versuch); der Seitentext liess sich nicht direkt lesen.]
Caveat
This figure rests on an inaccessible source (HTTP 403 on every attempt) plus corroboration from outlets outside the entry's four listed sources; it has not been confirmed against the Usine Digitale page itself.

Claim 9 clm-31996743ab9e7633 quantitative
under the EU InDiD programme (to 2023)
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Same access limitation as the funding-percentage claim above (HTTP 403 on every fetch attempt). Independent secondary sources consistently describe Paris2Connect as continuing 'within the framework of the European programme InDiD ("infrastructure digitale de demain") until 2023' — InDiD is reported as a genuinely EU-linked co-financing stream (Connecting Europe Facility) that runs alongside, not identical to, the City of Paris's own direct 25% budget share; other reporting lists local (Paris&Co Urban Lab), national (SAM/EVRA) and European (InDiD/CEF) co-financing as three separate strands. [find: null — Usine Digitale blockt automatisierte Abrufe (HTTP 403 bei jedem Versuch); der Seitentext liess sich nicht direkt lesen.]
Caveat
Could not be verified against the Usine Digitale page directly (HTTP 403 on every attempt). Also, as phrased, the entry's sentence can be read as saying the City's 25% share is funded 'under' the EU InDiD programme; independent reporting instead describes InDiD as a separate EU co-financing stream running in parallel with the City's own direct contribution and other local/national streams, not as the mechanism through which the City's own 25% was paid.
