Dublin’s Smart Traffic Project: How a Year of Upheaval Led to Citywide Change

Dublin’s long-awaited v85 Traffic Verification System officially launched citywide on Friday, marking the end of a fraught rollout that has tested the city’s drivers, businesses and planners for more than a year. The debut of this digital monitoring programme on July 4 means all private vehicles entering the city centre must now register and display their v85 sticker or face automatic fines.

Why the v85 Verification Now?

The v85 project is Dublin City Council’s response to unmanageable city-centre congestion. By July 2025, daily traffic volumes in the Molesworth Street and Merrion Square areas had jumped by nearly 14%, according to council reports, while average rush hour speeds in the College Green corridor dipped below 8 km/h for the first time on record. Businesses on Dawson Street reported record delivery delays, and air quality monitoring at South Great George’s Street reached its worst levels since 2020.

The old permit paper system couldn’t keep up as the number of vehicles soared and illegal parking remained rampant. Frustrations mounted after repeated enforcement blitzes failed to improve the Luas Cross City tram punctuality. The v85 system, approved by a council majority in October 2025, was sold as a way to tackle those issues through digital registration, GPS tracking and rapid enforcement.

How Dublin Got Here: From Pilot to Full Rollout

The system’s roots go back to a 2023 smart city pilot in Smithfield, aimed at limiting through-traffic on Capel Street and prioritising deliveries. After initial complaints from residents, the pilot was extended to parts of Ringsend and Phibsborough, where pressure from St Mary’s Hospital and local schools shaped the final design. The project gained urgency after the 2025 National Transport Authority data showed Dubliners spent an average of 62 hours stuck in traffic annually.

Over the past year, local businesses—particularly those on Baggot Street Lower and Camden Street—lobbied for exemptions but accepted a compromise: delivery vehicles registered with Dublin Chamber can access the zone until 11am each day. The council invested €13 million in new automated readers, the bulk of which were installed along the Quays and at the O’Connell Bridge bottleneck. Nearby, cycle use on North Earl Street has climbed by 37% since spring 2025 as motorists tried to avoid congestion and registration costs. As of this week, more than 82,000 vehicles are now listed on the v85 database, up from 41,000 at the start of 2026.

Registration costs €35 per year, with a €120 on-the-spot fine for unregistered entry. The city clerk’s reports suggest revenue from early fines could cover system maintenance for the first three years, though some local councillors warn of unintended impacts and administrative hiccups.

For residents and commuters, the advice is to ensure vehicles are registered at v85.dublincity.ie before entering the energy zone. The council promises an official review in October to address any teething problems and revisit exemptions. Until then, expect continued enforcement along all main city access points—from Christchurch Place to Dorset Street Upper.
