Two of Belfast's roads have been named among the ten most congested in the UK in 2016.
The report, by traffic and transport data experts Inrix, showed the southbound Lisburn Road from College Gardens to Wallace Park was the most congested road outside of London.
The study said that on average drivers spent just over two days (49 hours) stuck in traffic on the this stretch of road.
The A24 between the Ormeau Road and Ann Street in the city centre was also in the top ten for congestion.
The Inrix study examined 87 cities and large urban areas across the UK and estimated the cost, both direct and indirect, to drivers totalled £30.8bn, which works out at around £968 per driver.
This factored in variables such as wasted time and fuel as well as increased costs to businesses which are passed on to households by way of higher prices.
Despite the heavy traffic on a number of roads, Belfast was not among the ten UK cities worst afflicted by traffic jams.
