Overview
- An Apur study finds average noise down about 2.7 dB, with residents reporting noticeably quieter nights along the 35 km ring road.
- Traffic volume declined roughly 4% and both congestion hours and accidents fell by about 14% compared with the prior year.
- Île‑de‑France president Valérie Pécresse renewed her push to transfer management of the Périphérique to the region.
- Pécresse, citing the Institut Paris Région, argues users are losing around 20,000 hours per day, calling the measure antisocial.
- Airparif reports mixed air‑quality signals, with PM10 concentrations rising and NO2 levels falling, as the region proposes co‑funding more acoustic surfacing that Apur says loses effectiveness after about ten years.
