DUBLIN City Council has set out three options for dealing with the 30kph limit controversy ahead of a crucial transport meeting this week.
City officials have told councillors they can leave the speed restriction unchanged, reinstate the 2006 bye-laws or amend the boundaries of the 30kph zone.
The latter two options would require the introduction of new bye-laws, meaning a lengthy process would have to be instigated.
Thursday's special meeting of the transportation and traffic policy committee was convened following the furore over the council's 30kph limit on Dublin's North and South quays.
The meeting will also consider a motion submitted by councillors Henry Upton, Michael Conaghan, Dermot Lacey and Rebecca Moynihan.
It calls on the council to restrict the 30kph to an area on the quays between Capel Street Bridge and O'Connell Bridge.
The councillors also want the lower limit to be scrapped for Winetavern Street and Kildare Street in favour of a reintroduction of a 50kph zone.
Members of the public have expressed anger at the go-slow policy, while Conor Faughnan of AA Roadwatch has also been a prominent critic.
"In road safety terms, Dublin City is one of the safest places in the country. The road safety justification does not exist," Mr Faughnan said.
However, representatives from a dozen civic organisations urged councillors to maintain the 30kph speed limit.
In an open letter, the group said that 49 people lost their lives in the area in road collisions over the last 15 years while 300 people were seriously injured.
Signatories came from a wide range of bodies including the Children's Rights Alliance, National Council for the Blind of Ireland, An Taisce, Dublin Cycling Campaign and pedestrian advocacy group Cosain.
The longest delay caused by the speed reduction along the quays is 68 seconds which is "a small price to pay for safety", the letter stated.
The extended limit came into effect on January 31 and applies from Bolton Street in the north inner city to Kevin Street Lower and St Stephen's Green on the other side of the Liffey.
It was also extend from the Church Street and Bridge Street areas in the west to Gardiner Street, Tara Street and Dawson Street on the east.
