All residential areas across Dublin City are to see speed limits cut to 30km/h under new laws that will kick in next year.
According to the Irish Times, members of the council's traffic committee will be asked to approve the lower limits at a meeting this week.
It follows a public consultation that received more than 900 submissions, 700 of which supported slower speeds.
The city council has been introducing lower limits since 2007 when officials first reduced speeds from 50km/h to 30km/h in the shopping and central business district.
The changes will be introduced in three phases, starting with north-western suburbs in March that don't already have the lower limit in place, such as Finglas, Ballymun and Santry.
Areas like Ballyfermot, Rathgar and Clonskeagh in south Dublin will follow in June.
While the rest of the northeast areas, such as Donnycarney, Beaumont and Darndale will fall under the 30km/h zone by September.
