A new report shows that Dublin is the 17th most congested city in the world, with motorists spending an average of eight days and 21 hours sitting in peak traffic a year.
The TomTom Traffic Index examines the traffic situation in 416 cities in 57 countries around the world.
The report showed that congestion has risen across the country, especially in Dublin where waiting times have gone up by 3% in the last year.
TomTom noted that Dublin's ten most congested roads include Parnell Road / Grove Road, Dalymount / North Circular Road, Dorset Street Lower, Bothar Mhuirfean, Clanbrassil Street Upper, Drumcondra Road Upper, King Street North / Bolton Street, Church Street / Church Street Upper, Amiens Street and Harold's Cross Road.
"High congestion levels can indicate strong economic activity, but they also represent lost time, productivity and potential for Dublin's workers," said Stephanie Leonard, Traffic Advisor at TomTom.
"It's time for traffic to change and, while plans around congestion charges and new cycle lane networks will help the situation, they can't come soon enough," she added.
Meanwhile, Cork is ranked 75th in the world for congestion, but TomTom noted that congestion is set to reduce when the city's northern ring road is finished in 2027.
Limerick is ranked 118th in the world for congestion.
