Paris2Connect: shared sensor infrastructure & urban digital twin (13th arr.)
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 (12th/13th arrondissements): 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 and support public consultation. 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.
