Irish capital tops European rankings for rush-hour delays as experts warn transport system “skating on thin ice”
Dublin — Dublin has been ranked the 11th most congested city in the world, climbing four places from 15th position last year, according to INRIX’s 2025 Global Traffic Scorecard released by the American data agency.
While Dublin ranks 11th overall globally, it frequently tops rankings for rush-hour traffic congestion. The average Dublin commuter spends approximately 158 hours, or over six days, stuck in traffic annually, the highest figure in Europe.
Professor Brian Caulfield of Trinity College warned that Dublin’s transport system is in a precarious state, describing it as “skating on thin ice.” He noted that even a minor accident on the M50 motorway or in the city center can trigger major traffic jams lasting hours.
The average speed of vehicles in the city during rush hour is just 13.4 kilometers per hour, slower than cycling. When accounting for fuel and time costs, drivers lose more than €2,000 (approximately ₹1.8 lakh) annually due to congestion.
As of June 2025, more than 187,000 vehicles passed through the M50 highway daily, a record number highlighting the intensity of traffic pressure on Dublin’s road network.
Authorities fear the city will come to a complete standstill unless major projects such as MetroLink and BusConnects are accelerated. The findings underscore urgent need for investment in public transport infrastructure and alternative mobility options to reduce car dependency.
The congestion crisis has significant economic implications beyond individual costs, with the Department of Transport estimating total congestion costs for the Greater Dublin Area at approximately €330 million annually, forecast to increase to €1.5 billion per annum by 2040 without intervention.
Transport advocates argue the rankings demonstrate the failure of road-building strategies to solve congestion and highlight the necessity of prioritizing public transport, cycling infrastructure and land-use planning that reduces travel distances.
The government’s €20 billion National Development Plan transport investment, including MetroLink construction beginning in 2028 and expanded BusConnects corridors, represents an attempt to address the crisis, though critics question whether these measures will be delivered quickly enough to prevent further deterioration.
