Operation Freeflow has been hailed for luring more Christmas shoppers into the Dublin city centre.
The traffic management initiative winds up today after its tenth year in operation.
Freeflow was designed to facilitate the swift passage of 700,000 consumers and business people through the capital each day.
Dublin Chamber of Commerce today praised the six-week initiative for bringing more consumers into city centre shops, pubs and restaurants.
Chief executive Gina Quin said: "In previous years, people may have chosen the out-of-town shopping centres like Blanchardstown, Tallaght and Liffey Valley, but they all seemed to be back in their numbers again this year.
"A lot of work was done to promote the unique atmosphere and experience of shopping in the city centre during Christmas and the New Year.
"Freeflow definitely helped. Things would have been a lot worse if it wasn't in place."
Operation Freeflow assigned gardaí to 170 traffic black spots, expanded public transport services and provided five park-and-ride facilities on the city's outskirts.
