Planned expansion of 30km/ph in Dublin City

The Transportation Strategic Policy Committee will begin the process of considering whether to expand the areas included in the 30 km/ph speed limit within Dublin City.

As outlined at the November 2017 Transportation SPC Meeting, Dublin City Council has committed to a review of the Special Speed Limit Bye-Laws this year. Included in the draft Dublin City Council Special Speed Limit Bye-Laws 2018, is the third phase of the 30 km/h speed limit roll out, highlighted in red, which has included a review of the arterial routes around the city and also examined additional areas for inclusion in the 30 km/h zones. Dublin City Council has also included in this review a pilot scheme where the periodic speed limit of 30 km/h would be introduced outside Schools on Arterial Routes which are unlikely to have the speed limit reduced on a full time basis.

Arterial Routes Review:

Having reviewed the Arterial Route Network around the city taking factors such as road legibility (layout), road classification, length of road etc into account, Dublin City Council is only reducing the speed on one arterial route. The change will see the speed limit of 60 km/h on the Howth Road between Brookwood Avenue / Sybil Hill junction to the junction with Ennafort Road / Cill Eanna reduced to 50 km/h (this section of road has been removed from the Second Schedule).

30 km/h Zone Expansion:

Based on the success of the first and second phases introduced last year, Dublin City Council is proceeding with a proposed expansion of the 30 km/h Zones. This expansion will not only focus on the core reasons for the speed limit but also take cognisance of the many representations received over the course of the last year. It is planned to proceed where possible and expand the zones organically providing consistency throughout various areas as motorists move through them. A revised map is attached to this report outlining the existing and new proposed 30 km/h zones. A pdf version is also attached where areas can be more closely examined by interested parties. The proposal includes 12 additional zones on the south city and 19 on the North city.

Periodic Speed Limit:

Finally, Dublin City Council will also be proposing the introduction of a periodic speed limit of 30 km/h outside schools on Arterial routes where the reduction of the speed limit is unlikely on a full time basis. In this review there are five schools to be included in the pilot scheme, entries 4 to 8 inclusive highlighted in red in the Fifth Schedule, and based on the successfulness and the availability of funding, the scheme will be expanded in future phases.

Recommendation: It is recommended that the Transportation Strategic Policy Committee refer the Draft Dublin City Council Special Speed Limit Bye-Laws 2018 to the full City Council for approval to initiate the public consultation process.

Should the Transportation Strategic Policy Committee adopt this Report tomorrow (April 19th) then it will be the May City Council meeting which initiate a public consultation on the matter. Please let me know what you think of the proposal by emailing me at
