New speed limits in south Dublin

A new speed limit structure for motorists in the Dún Laoghaire-Rathdown County Council area came in yesterday.

A 30km/h pilot scheme has been adopted in a number of areas in order to better match maximum speeds to local road conditions, the council said.

Several roads in Glencullen and Ballybrack have also seen their speed limits reduced from 80km/h to 50km/h.

The main N11 route from Foxrock church to Loughlinstown roundabout now has a speed limit of 80km/h which is an increase in some sections.

Speed Limit Frequently Asked Questions

Why are the speed limits being changed?

There are a number of speed limits within Dún Laoghaire-Rathdown that are not suitable for the road to which they apply. These new Speed Limit Bye-Laws aim to reduce/increase the speed limit to a more appropriate one.


What Speed Limits are being changed?

A brief summary of the changes are as follows:

Road| Previous Limit| New Limit

Glencullen and Ballybrack areas| 80kph| 50kph

Traffic Lanes on the N11 from Foxrock Church to Loughlinstown Roundabout| 60kph / 80kph| 80kph (along entire length)

Bus Lane on the N11 from Foxrock Church to Loughlinstown Roundabout| 60kph / 80kph| 60kph (along entire length)

Sallyglen Road| 50kph| 60kph

Fosters Avenue R112/ Mount Merrion Avenue N31 / Rock Road R118/ Frascati Road N31| 60kph | 50kph

M50 from the boundary with South Dublin County Council to Junction 14 Sandyford| 100/120kph| 100kph

Georges Street Dún Laoghaire, Stonebridge Road, Shankill and Broadford Road, Ballinteer| 50kph| 30kph


Who was consulted in the making of these Speed Limits?

Dún Laoghaire-Rathdown consulted with An Garda Siochana and the National Roads Authority and also carried out extensive public consultation, which included public displays and information days where Transportation engineers were available to discuss the proposals.


When will the new speed limits be rolled out?

These new speed limits will come into affect on Monday 11th January 2009.


How do I know what the speed limit is on a particular road?

A new type of signage will be erected as you enter Dún Laoghaire-Rathdown County Council’s jurisdiction to inform drivers that the speed limit is ‘50kph unless signposted otherwise’. With these changes to the speed limits the majority of roads within the County will be 50kph. Those that are not will be signed as you enter them. If you are in doubt of the speed limit, assume it is 50kph.


Where can I find out more about the changes?

A more detailed description of these changes as well as information on why the limits were selected is available on the Council’s Website (www.dlrcoco.ie) in the Transportation – Traffic Section.


What else is the Council doing about Road Safety?

Dún Laoghaire-Rathdown County Council has one of the safest road networks in the country with a fatality rate of approximately three times less than the national average and with on of the lowest injury rates in the Dublin Region. Dún Laoghaire-Rathdown is committed to road safety and has an ongoing programme which includes the following initiatives:
* Funded School Warden Service which trains and oversees 73 wardens at 65 school crossing sites
* Installed almost 200kms of cycle tracks throughout the County
* Delivered Road Safety programme which in 2009 included on road child cycle training, the first of its kind in Ireland
* Installed enhanced pedestrian crossings and facilities for those with visual and mobility impairments
* Improved infrastructure in areas with identified accident problems through Accident Investigation and Improvement Schemes (AIP)
* Installed speed alert signs in areas with an identified speeding issue

Well good to see the N11 is up to 80km/h now anyway, traffic never moved anywhere near 60km/h on it. I could never remember which parts were 60 and which were 80 anyway, it was a bit all over the place.

Victor

The city section (from the Belfield Overpass) is still 60 km/h. However the city did indicate it would review the limit when DLRCoCo sorted theirs. However, as the city limits were only changed recently, it may take 2-3 years.

Its not as easy to change the city section due to more private entrances and pedestrians and cyclists.

Cookie_Monster

Why on earth is the M50 limit being lowered :mad:
Is this just because the rest of it already has been.

Good new on N11. I can't think of any road in Ballybrack that was 80 though.

Pity DL is even slower now, though you rarely got to do 50

L1011

Its being lowered "From SDCC boundary to J14", which is the section we always knew was going to be lowered. The SEM will still be 120km/h.

More non TSM compliant "homemade" signage on the way then?

If you are in doubt of the speed limit, assume it is 50kph.

I reckon DLRCC could be walking themselves into a leagal quagmire with this. Instructing drivers to assume 50km/h "if in doubt" is also plainly stupid when they are introducing a 30 limit. Can I assume 50 in these 30 areas too, assuming I don't see the 30 sign?

I saw one of those signs recently and was very confused. Surely the standard urban speed limit applies unless otherwise indicated? What's the point of these?

Moreso confusing when you consider that for many people (espeicially those not from the area), Dun Laoghaire - Rathdown is not a county, and will not be aware if they are in it or not!!

Changing the Sallyglen road from 50 to 60?? Is it worth it?

No one takes a blind bit of notice of the speedlimit on there anyway.

I entered DLR Co. Co. jurisdiction yesterday evening but didn't see this new type if sign.

I agree, it went up and down like a yo-yo for no apparent reason and was difficult to keep track of, and the 60km/h bit approaching the Loughlinstown roundabout was just ridiculous.

The Garda won't be happy, they are always setting up there North/South (near the Esso stations).

They'll just move up to the Cherrywood exit which is another favourite of theirs anyway

I would assume as it's grouped with Glencullen it referes to the Ballybrack Road (R116) which runs west from Glencullen.

Victor

Curious is the 120km/h off ramps.

Cookie_Monster wrote: »

With the extra lane, each lane is going to be narrower. It is also a slightly complicated junction.

Part of the metrification process back in 2005 was that the old National Speed Limit (black diagonal line) sign was abolished. Pre-2005 a road was by default NSL (60mph) unless signed otherwise. These signs would appear to be harking back towards those days.

However part of the metrification process was that there was no longer to be any default speed limit. Every single piece of road in this state was to have a signposted speed limit. Therefore one cannot "assume a road is 50 km/h unless you see otherwise", because one must always take note of the signed speed limit.

Long and short - the speed limit is always what the last speed limit sign you passed says it was. Don't assume anything else no matter what DLRCC are saying.

In built up areas its a default 50 and rural its a default 80 isin't it?

Cookie_Monster wrote: »

Er, not always. The "default" (in so far as one exists) rural limit is 80km/h on an R-road or L-road, but 100 km/h on an N-road. That's assuming a works limit has been put in place, or a lower limit for some other reason etc.

Likewise in many urban areas (including large parts of Dublin) the limit is 60 km/h.

There is no real "default" speed limit in the Republic of Ireland any more. We took the old limits and translated them to km/h - what needs to be noted is what we did with the old NSL limit which was the dramatic change...

Old 30mph limit = 50 km/h
Old 40mph limit = 60 km/h
Old 50mph = 80 km/h
Old NSL = on N-roads 100 km/h, on other roads 80 km/h
Old 70mph = 120 km/h.

Narrower lanes plus lowering the limit (within reason!) gives a higher capacity from the same road space.

Red Alert

The problem with Broadford Road in Ballinteer is that it's the main access route from Ballinteer to Nutgrove and Churchtown, and architecturally it's built to be a main road. They've already put ramps on the damn thing!

There are several large schools there.

drove from Loughlinstown to Stillorgan along the N11 today - plenty of 60 Km/h signs still up - has this change come into effect yet?

I would put adequete crash barriers in place where necessary, and otherwise bring back the "Safe Cross Code" - there's a culture of nannyism developing in transport regulations. People should be made cop on and take responsibility for their behaviour, both school children and motorists. Putting overly onerous speed restrictions in place doesn't do this.

Research backs lower speed limits as a proven, effective safety measure.

As for crash barriers? If you're referring to steel railing -- if so these have been identified as creating a dangerous environment for cyclists. And, anyway, would any type of crash barriers on normal streets not be "a culture of nannyism"?

Red Alert

Sure why not reduce the speed limit to walking speed instead then? I meant pedestrian railings, which are designed to discourage people from crossing in dangerous locations - not motorway-style crash barriers.

Pedestrian railings are also dangerous for cyclists as they can be caught between them and a car overtaking too closely.

Because, as you know well, walking speeds would grind the place to a halt.

There's good backing for 30kmph...

Reducing the speed limit to 20 mph [32kmph] in urban areas Child deaths and injuries would be decreased
Paul Pilkington, trainee public health specialist, South West Region
London School of Hygiene and Tropical Medicine, London WC1E 7HT
...

The evidence of increased pedestrian safety at 20 mph [32kmph] is strong. The chance of a pedestrian being seriously injured or killed if struck by a car is 45% if the car is travelling at 30 mph [50kmph, or to be more exact, just over 48kmph] but only 5% at 20 mph.6 Government research showed that 20 mph zones reduced the incidence of traffic accidents by 60% and cut child pedestrian and child cyclist accidents by 67%, while overall vehicle speeds fell by an average 9.3 mph (14.9 kph).7 There was no evidence that accidents increased on surrounding roads. Research by local councils produces similar results. For example, Havant Borough Council has imposed a 20 mph limit on 20 miles of road and has seen traffic accident casualties drop by a significant 40%.8

Red Alert wrote: »

As mentioned above pedestrian railings are dangerous for cyclists.

The railing are also costly, and not as effective. You can't have railing everywhere or cost would increase massively (potential danger of cyclists would also increase). Also the idea of railing in general, never mind everywhere, would "a culture of nannyism" in the extrema. Railing only cover a small part of roads, so these are not as effective as reducing speed on a full road to 30kmph. And, more generally, the effectiveness of railing is not as proven as reducing speed.

They've (mostly) re-signed the loughlinstown bit, now officially 80. They're using a dual sign with 60 for the bus lane and 80 for cars on it.

Hang on. Are you saying cars (primarily taxis) are allowed do 80 in the bus lane?

astrofool

it being the two lane N11, not the N11 bus lane, sorry for not being clear.

Victor wrote: »

No. The bus lane is indicated as 60, the other two lanes as 80.

Just another unnecessary complication to the Irish road rules when the basics are not adhered to by so many.

TBH I normally avoid the bus lane in both directions between Cabinteely and Loughlinstown anyway and certainly will in the future. The multiple entrances in particular the two service stations (where muppets throwing their cars infront of buses and slamming on their brakes is a daily occourence) made it dangerous when the whole section was 60kph. It is not going to be any better now plus I would run the risk of a speeding ticket when I could go faster in the other two lanes legally.

The section between Foxrock and Cabinteely was always 80kph so the only change here is the lower limit for the bus lane.

Cookie_Monster

The bus lane spped is a bit odd I think. The only reason I can see for it is to try keep non bus traffic out by making the other two lanes faster.

Double deckers (the main bus on the route) can only legally do 64pkh anyway

For cyclists, having taxis or coaches whizz by at 80km/h (or faster) isn't nice.

Its a separate lane for bikes along there (grade separated mostly) and I don't see how/why it should affect them in the slightest whether the bus/car is doing 10/60/80 or 100.

Has the limit on the Glenageary Lodge Rd been increased lately or has it always been 60kph.....i thought it was 50kph...

I'd love to see if the split lane speed limit signs and the "50 unless otherwise signed" ones you get crossing the county boundaries are actually legal at all. Something tells me they aren't...

50 is the standard speed limit for urban areas. I guess these are warnings in addition to, rather than replacments for 50 signs?

The diffrent speed for diffrent lanes is another question.

The signs may not be provided for in legislation, but that doesn't necessarily make them illegal.

It is legal to have different speed limits on different lanes.

If they are the only signs designating the speed limits, and do not exist in legislation, you're not going to find it hard to get tickets thrown out if you can show the last correctly formed sign you passed was high enough.

It was ridiculously slow for such a nice road. It will probably never go to 80 because of the school/pedestrian lights.
