    Thanks typewriter I wrote that 2 pages ago.

    NRA for now until they are merged the the Railway Procurement Agency; RRPA may be an apt title; Road,Rail Procurement Agency
    Take it that both Anto and I know the traffic counter is south of Gort, you then used the data as an argument in this here post.

    I made two comments on the overall project in that post and clarified my opinion below:
    At a cost of €500m in a much cheaper construction environment this is far from a cheap road. The Tuam section may be 2 & 2; the reality is that a lot more of the route should have been 2 & 2.

    Where does that say that I thought the M18 should not have been built from any point South of the M6?
    every kilometre of motorway removing 25 to 30 acres of land from agriculture, the road building authority gambles that a future government can be browbeaten into building around 800km of motorway after it has bought some 22,000 acres of land,

    If you build there entire Atlantic Corridor from Tuam to Letterkenny that would be at least 300kms and that has been discussed on numerous forums; N2 to Monaghan another 100 kms; Gorey to Waterford 80kms, Midleton to Rosslare 130kms? Rathkeale to Castlelisland ? Killarney to Ballyvourney? If you trawled every TDs website you'd probably get commitments to 1,200 kms.

    And you still have not apologised to the RPA staff for that outrageous slur.
    I have removed the typos and put the NRA in; they do have some explaining to; again their advice on the M3 might just have been ignored; but unless they made it clear and were over-ruled by a minister keen to deliver a white elephant to his own patch then they have a lot of explaining to do; the M3 should never have been built with the M2 draining most of the commuter hinterland of South Meath on a free gratis basis.

    None of this is to be built to Motorway standard bar maybe 20km near Sligo. That is none ...as in NONE ....as in zip. Much of what you describe as Motorway will even be built as standard single. EG around Ballyvourney.

    Standard Single not = Wide single....don't even try to go there :D

    All of this hysteria over nothing. Me, I blame the Irish Times for listening to the eco nutjobs when a calculator and 5 minutes usage thereof would have proven they were screming hysterically over nothing :(

    The primary claims in the article were the tolls shortfall and the purchase of land for schemes that they didn't have funding for including the scheme below;

    N30 Clonroche (Templescoby) to New Ross

    Local Authority:Wexford County CouncilStart County:WexfordEnd County:WexfordDescription:13.5 km realignment of the existing N30 between Moneytucker and the New Ross Bypass incorporating a bypass of Clonroche.

    This project has been funded by the Irish Government under the National Development Plan and Transport 21.

    Mainline Length (km):13.5 kmCurrent Project Phase:Preliminary Design

    A spokesman for the NRA said it had “no comment” to make on Plan Better’s claim.

    They could do themselves a favour by setting out exactly what they are doing; if they don't stand to incur a shortfall then FmD is clearly exposed; if they are not purchasing land ahead of funding then they have nothing to hide. There is no way the future NRA motorway / type 2 DC programme beyond currently contracted schemes is a mere 20 kms; they have their sights set on significantly more; clearly there is a large staff there which has been built up whilst the main network was delivered; it will be hard for them to scale down to fit the lower requirement and tight fiscal position.

    I have no recollection of arguing against a road north of Gort to the M6; I look forward to seeing you post where I did argue against it.

    The RPA entered were party to a contract on M3 which contained minimum traffic levels did not materialise upon exposing the taxpayer. If the RPA don't advise on scoping and overseeing the scope and design of roads then what is their function? Other than buying land for schemes they don't have funds to build?

    Scroll down to the N18 counter for Gort on this page and you will see the following:
    N18 6km south of Gort (IG: 145352E 196899N)

    You can also view traffic counter locations on this map.

    The Gort one is to the South of the town. It wouldn't even take Gort-Galway commuter traffic into account; nevermind the commuter traffic from all the other towns/villages between Gort and Galway.

    Navan North

    We are all still waiting for you to point out your concerns on one road scheme; surely if you examined every line of every specification you would have found something worth posting. Clearly on Navan North this has not happened on a number of levels; with an AADT of 8,000 for a motorway; please explain how this represents value for money to the taxpayer. I think unless the NRA can produce advice to Noel Dempsey saying this scheme failed a cost benefit analysis then I think there need to be resignations from the NRA or dismissals.

    Hello again, Roads friends.

    If motorway construction is being queried in the media, do people around here just stick their head in the sand or what?

    Discuss!!:

    THE €36 million cut in funding to maintain local and regional roads announced last week has been condemned by PlanBetter, which described it as “the other side of the coin of excessive motorway construction”.

    PlanBetter said Ireland had 2½ times more motorway per person than Britain. “Yet plans by the National Roads Authority to build another 800km of motorway have still not been officially shelved,” it said.

    “Over the next three years more than €275 million will have to be found to make further motorway repayments, even as traffic on them falls, and this burden will result in further cuts in budgets to fill potholes and resurface local and regional roads.”

    It said removing accident blackspots saved far more lives, per euro invested, than motorway building. “The Department of Transport and the NRA are perfectly well aware of this, but seem engaged in delusion while the wrongful allocation of taxpayer funds persists.”

    The outgoing government used the four-year plan to falsely claim that every Transport 21 project was still viable. The incoming government needs to be honest, and openly acknowledge that long sections of motorway are as unnecessary as they are unaffordable.”

    If you are going to post a news article don't just post the sound bites.

    THE €36 million cut in funding to maintain local and regional roads announced last week has been condemned by PlanBetter, which described it as “the other side of the coin of excessive motorway construction”.

    This joint initiative by An Taisce, Friends of the Earth, Friends of the Irish Environment and Feasta noted that the cut represented nearly one-third of an estimated €105 million needed this year to service borrowings on “unnecessary” motorways.

    “The recent announcement maintained a 14 per cent cut in the low-cost safety improvement programme, which is used to remove accident blackspots on dangerous roads all around the country and stands at a paltry €6 million a year.” PlanBetter said Ireland had 2½ times more motorway per person than Britain. “Yet plans by the National Roads Authority to build another 800km of motorway have still not been officially shelved,” it said.

    “Traffic is 20 to 30 per cent below the level projected by the NRA on some new motorways, including the M3 via Tara.

    On top of loan repayments, taxpayers are also paying penalty fees to make up for less-than-expected revenue at the M3 toll booths, the group said.

    “Over the next three years more than €275 million will have to be found to make further motorway repayments, even as traffic on them falls, and this burden will result in further cuts in budgets to fill potholes and resurface local and regional roads.”

    PlanBetter noted that half of the Republic’s road network scored the lowest possible safety rating by the European Road Assessment Programme, compared to only 5 per cent of Northern Ireland’s network and just 2 per cent of roads in Britain.

    It said removing accident blackspots saved far more lives, per euro invested, than motorway building. “The Department of Transport and the NRA are perfectly well aware of this, but seem engaged in delusion while the wrongful allocation of taxpayer funds persists.” Fred Barry, the road authority’s chief executive, recently told the Oireachtas Committee on Transport that many existing roads do “not come close to meeting current design and construction standards” while others “were never properly designed in the first place”.

    Yet PlanBetter said over €1.7 million was “misspent” planning a 28km dual carriageway in Co Wexford between Oilgate and Rosslare. “More than 20 accident blackspots across the country could have been eliminated with this money,” it claimed. Instead of planning new motorways, which then “turn into subsidised toll roads”, it said a new approach was needed by the next government.

    “Dedicated bypasses with selected enhancements along existing routes are what’s required. The outgoing government used the four-year plan to falsely claim that every Transport 21 project was still viable. The incoming government needs to be honest, and openly acknowledge that long sections of motorway are as unnecessary as they are unaffordable.”

    Where are Planbetter getting the 800km figure from? Could it be that they just made it up?

    BTW, Cress, it would be nice if you contributed more actively in your own thread. If you don't contribute actively, it looks rather like you're just stirring or mischief-making to be honest.

    Also, most of the road deaths occur on N roads scheduled for upgrade, not R-roads. A toddler killed last week on the N20 for instance, due to be replaced by the M20. What a pointless waste of money on removing that blackspot, eh (the blackspot in question being the entire N20)?

    N72 claimed another life over the weekend: it cannot be upgraded online; I say a new build is really required, but the NRA have no plans for this admittedly.

    The N28 - another accident blackspot. NRA solution: build a new, safe, 13km dual carriageway. The current N28 cannot be upgraded satisfactorily, so a new build is necessary.

    N24: one of the most consistently deadly roads in the country. If PlanBetter want to reduce fatalities on the N24, get behind the NRA's plan for a new offline type 2 dc N24. Ditto N17.

    Otherwise stop talking out of both sides of your mouths.

    Some Facts:

    Using all available NRA automatic traffic counters 2007-2010, traffic has reduced by 6.1%. The trend of reduction is greater year on year. The CSO freight survey 2009 showed 40% reduction in freight from 2008. in the UK traffic has also fallen for 3 consecutive years the first time since records began in 1949. The UK traffic model is run yearly and refined and quite frankly makes the NRA's model look like a child's abacus. It predicts growth of traffic of 0.5%/yr. with a sensitivity analysis accepting negative growth. So the NRA over-specifies roads on traffic forecasts designed by RTL in 2003 predicting 2-3% annual growth. NRA road layouts are funnily enough very similar to those of the UK. Something to do with the fact that of 189 documents in the NRA DMRB 173 come from the UK DMRB. Anyway the roads are the same yet UK max. capacities for say dual carriageway are 143% greater so the UK can put more traffic on the road before upgrading to expensive motorway. The NRA removed wide singles and 2+1's for greenfield constructions in 2007 so you jump straight from stand single carriageway to 4 lanes. Motorways offer the lowest number of lives saved for any road design element I know the have a BCR in terms of safety of 0.15 i.e for safety more costs than benefits. Irish roads in the last EuroRAP report had 50% at the lowest 1 star rating compared to NI 5% and Britain 2%. Fred Barry in committee on 12/01/2011 said many Irish roads where not properly designed in the first place and are substantially below international standards. You don't need 4 lanes lads you ain't got the money you need to get with the programme and start designing safe cheap middle sized roads and upgrading the 94% of roads that aren't motorway. By the way if any of you think of saying 2+2's are middle sized how come a whole load of them got reclassified as motorway in 2009. Stop wasting other peoples money and start thinking! From one of the authors of that Irish Times piece you so glibly dismissed. The jokes on you fellas not me.

    Sorry no 2+2 roads were reclassified as Motorways. What was reclassified is what's called HQDC (High-quality Dual carriageway) -- in other words narrow median motorways with green signs.

    2+2 roads have:
    • no hard shoulders
    • Compact grade seperated junctions
    • Can have roundabouts at terminal/start positions
    • Wire barrier instead of concrete crash barrier

    Here's a pic of the N4, apart from the flyover it's fairly equivalent in overall roadwidth as a wide single carriageway

    What is a fact is that divided roads with two carriageways are much safer than a non divided road. The reason is that it reduces head-on collisions which account for a large amount of roads deaths and provides safe overtaking leading to less frustration. 2+2's Type 2 dual carriageways (see above photo by dubhthach) cost close enough to the price of a normal wide single carriageway road. Why would you build proven unsafe roads when you can pay 1-5% more for a well known safe road.

    Has there even been a serious accident yet even on the Dromod-Rooskey N4 bypass? It been open to traffic for a few years now.

    Most later period WS2s had minor roads on flyovers/underpasses to begin with too.

    A 2+2 is the same profile as the Charlestown BP, the Kilmacthomas BP, the N30 realingment between Clonroche and Enniscorthy, etc. It is not the "motorway" that our Slane Bypass ranters seem to insist it is, nor is it upgradable to one.

    Of course, facts are thin on the ground in PlanBetter's arguments, even when they're extremely easy to find out.

    “The recent announcement maintained a 14 per cent cut in the low-cost safety improvement programme, which is used to remove accident blackspots on dangerous roads all around the country and stands at a paltry €6 million a year.”
    Hang on a sec, didn't we try that in the late 80's & early 90's - from a road safety point of view it didn't work (the numbers of road deaths was still shockingly high until the introduction of penatly points) and hasn't helped journey times.
    PlanBetter said Ireland had 2½ times more motorway per person than Britain.
    So we have beteen 800km and 1000km of motorway all leading to our main city, nothing to connect the 2nd, 3rd and 4th cities to each other (we're trying to but it appears that these groups don't want this) - before we talk about the other large urban areas. Britain has such a motorway system - with many more major connections to boot.
    “Yet plans by the National Roads Authority to build another 800km of motorway have still not been officially shelved,”
    Why should they be shelved? There are 2 schemes due to launch this year and 2/3 more over the next 4 years. That 800 KM must relate to projects that are part of a strategic plan for the country's transport network. We can't have one of these can we - we're irish we don't do such things:mad:

    PlanBetter noted that half of the Republic’s road network scored the lowest possible safety rating by the European Road Assessment Programme, compared to only 5 per cent of Northern Ireland’s network and just 2 per cent of roads in Britain.

    It said removing accident blackspots saved far more lives
    I can't think of a better way of remving blackspots than removing traffic from the raods that shouldn't have to use them - motorways does this
    “not come close to meeting current design and construction standards” while others “were never properly designed in the first place”.
    Seems to me that the NRA believes that upgrading roads to be safe is a more expensive and time consuming proposition that - especially when there are no alternative routes available or are more dangerous than the ones being fixed (something that many serial complainants just don't comprehend)

    “Dedicated bypasses with selected enhancements along existing routes are what’s required.
    Absolute horsesh*t. I spent a couple of years driving between Dublin and Galway before the M6 fully opened. It was 220 KM door to door. The sped limit on the road was 100 KM for most of this, so I have a reasonable expectation of being able to do this in about 2.5 hours.

    Kinnegad is 100 Km from my place in Dublin, I can get there in a little over an hour, leaving in the late evening, missing all rush hour traffic. From there on the road was an absolute nightmare - it used to take 2 hours to drive 120 km - on a dry evening/night - impossible to pass die to narrow/winding stretches or traffic on the straight stretches, safety vigilantes (if I can't do any more that 65 km/h, you can't either and I'm making sure you don't get past:mad:) etc. Funnily enough it was quicker on wet days (light drizzle that wouldn't yet your hair), as if the sunday drivers and safety crew deemed it too risky to be out driving.:rolleyes:

    It situation only improve slightly as the new sections opened (always took 1 hour 10 mins to get from the carnmore cross to the d/c the far side of ballinsole, only 63km). It seemed that people were driving slower that they had been on the single carriage way roads as more DC/Motorway came on stream (wtf is up with that - the road, barring a couple of bits in ballinsaloe hadn't degraded any).

    Dedicated bypasses do not work as the rest of the road system is not up to scratch (didn't Fred Barry say that too), we need full HQDC (which are built to the same standard as motorway).

    Every 2+2 road is being described as a motorway by the anti road groups around the country. The only motorways needed in the future will be the M17/M18, M11 and M20 which is enough. Also the HQDC bypass of Galway city.

    All of these proposals have usual cultural cringe of Britain this and Britain that. Britain is essientially England, which has quite a different population distribution than Ireland. Why not use Denmark as a comparision which has over 1000km of motorway? Denmark has many other appealing features, they have closed a bank and burned the bondholders, for instances. But even from a transport perspective they have good cycle networks, rail and bus networks, illustrating that building motorways does not preclude these things.

    There is scope for a debate as the most urgent motorways have been completed and the exact standard (motorway, 2+2, etc) of remaining improvements should be open to debate. But dishonesty and calling non motoways roads motorway is no help.

    Where are you getting this from? Also, how exactly was the 6.1% fall in traffic on the entire network calculated? I can't look through all the traffic counts right now, but I have a feeling that the 6.1% figure is either incorrect or misleading (for this discussion).

    Anyhow, many of our motorways were not built because the N roads that they were replacing were full to capacity....
    • Economic Activity: journey times between key economic hubs were judged to be unacceptably high, and rightly so. The N6/4 was not full to capacity but Galway-Dublin journey times of up to 4 hours were not at all acceptable in economic terms; East Galway City to the M50 can now be done in 1 hour 30 mins. Cork-Belfast used to take roughly 8 hours even though most of the route was not full to capacity; it can now be done in 4 hours.
    • Future Proofing: we don't ever want roads that are full and congested. By building key routes to a high standard, we are future proofing these important routes for many decades to come. It makes sense to do this; we could spend a little less now by building roads with the capacity that we need now and in the next decade or two but it would end up costing us more in the long run.
    • Safety: I know you argue that more lives could be saved by instead spending the money on improving other non-motorway roads. However, the point still stands that motorways do improve safety a lot. Safety is just one reason for building motorways and it is not the only one, there are many more.

    I think we've found out why people from An Taisce, Friends of the Earth, Friends of the Irish Environment and Feasta always object to everything. They were born miserable
    Some people cannot help being pessimistic, suggests a new study that found the amount of a chemical in the brain affects how we view the world.

    Researchers discovered that levels of a molecule called neuropeptide Y (NPY) directly relates to whether we have a "glass half empty" or "glass half full" attitude towards life.

    Those with lower levels of the substance are much more negative

    Since An Taisce is supposed to be (or used to be at any rate) state backed, maybe we should test people in it for this chemical and prevent them from talking in public.

    All of these proposals have usual cultural cringe of Britain this and Britain that. Britain is essientially England, which has quite a different population distribution than Ireland. Why not use Denmark as a comparision which has over 1000km of motorway? Denmark has many other appealing features, they have closed a bank and burned the bondholders, for instances. But even from a transport perspective they have good cycle networks, rail and bus networks, illustrating that building motorways does not preclude these things.

    It really sickens my wick when people continuously look to England for comparisons. I agree with the point about Denmark. Also look at France - great motorway system, fantastic train system. Or Spain, with all the High-Speed Rail they're building now (now that their roads are complete - which is why you'll find them building roads here).

    Most people on this forum are not pro-roads and anti every other form of transport. Most are pro proper planning and development of infrastructure - roads first because we're so far behind, but also bus/cycle lanes, greenways (like in Mulrany, for instance), proper development of rail (and not that piece of crap called the Western Rail Corridor, that runs forty minutes slower than the bus :eek:) .

    BTW, I heard some fella called James interviewed on Drivetime last night - was that James Nix, does anyone know? It sounded a lot like what was in the Irish Times article. I was driving at the time, and I nearly crashed the car, I got so annoyed at the crap he was coming out with. I switched if off - I couldn't take any more.

    To all those who moan about falling road usage and motorways not needed, a couple of points;
    • First motorway built in 1924 (Milan-Varese in Italy) IS STILL IN USE!
    • Motorways are like the canals of 18th century and railways of 19th century - physical LONG TERM infrastructure
    • Road usage rises and falls periodically - year in year out stats are irrelevant when talking about long term infrastructure.
    • Of course planning for the future should continue IMO. Land prices are rock bottom. The NRA should be banking land for future schemes. Remember land costs at the height of the boom cost 35% of construction and was one of the biggest reasons for delays.
    I think we did well to get what we got, but there is still a lot of catch-up to do. Italy started in 1924, the UK in 1958, Ireland in 2001.

    too many queries in 1 day to answer all but I'll try a few. That is not to say I won't answer the rest because I will if you think you have me, keep posting. I'll reply once a day.

    • The re-designated motorways were some 2+2's. This is a direct cut and paste from a communication with the NRA:
    "The new roads and re-designated roads are Type 1 Dual Carriageway and
    Type 2 (2+2) Dual Carriageway."

    • The growth data came from all available NRA automated traffic counters with data between 2007 and 2010. The CSO is presently calculating traffic by a different method. They too have problems with lack of data as they use odometer readings and funnily enough they do not get read once at the beginning of the year and once at the end of the year so you get readings say in mid 2008 and beginning of 2009 that gives traffic values that partly reflect the year prior. I was asked by the CSO how to treat the data to overcome this issue. I directed them to the head of statistics at the ITF. I did that deliberately to keep myself away from the work. Anyway this should be out in a month. I too want to know the truth on the issue but an educated guess suggests traffic reduction not growth. Using UK forecasts seems very reasonable considering the team they have and the model they use.
    • Regarding being an environmentalist. Well I'm not. I just spent today with Prof. Morgenroth, head of transport economics at the ESRI working through some data on safety rates and costs for different road types. He's not an environmentalist either we both worked for free just to give you a choice, aren't you lucky. The take home message is you can build more WS2 than dual carriageway and save more lives that way across the nation. I know some of you will be choking on your night-time cornflakes with that one, but its true. Read O’Cinneide et al 2004 paper and do the maths yourself. I'm not saying go back to WS2 necessarily but a mid cost option needs to be developed and fast.
    • WS2 is not similar in cost to 2+2 or dual carriageway we used freely available UK values for DC and WS2 for the prices. The NRA got a bit sheepish and said it depends on where you build it when I asked them for prices. I countered does that mean the quoted only 10% more from 2+1 to 2+2 is equally thus rendered inaccurate they said no. You can't have your cake and eat it. Well not for long gentlemen. Be a bit more open.
    • Some of you gentlemen are clearly in the trade if you want to be sat on your arses or picking up your P45's in the next few years keep on ridiculing my work. The NRA is this countries best hope for a coherent road network. That is providing it can adapt to give value for money not gold plated vanity projects. I hope to persuade them of this. But at present I'm getting little cooperation. Many politicians talk of valuing the contribution the NRA has made and wondering if it has a future roll. I have actually argued for its existence with these people but god knows why because they give precious little out with which to promote a reasonable strategy.
    • Regarding the link to the M3 clonee/kells and Limerick Tunnel toll press. That was my work all original, many thanks. The way those contracts are written with hard numbers for traffic each successive year with the usual growth multiplier attached as opposed to offering a traffic guarantee as a percentage higher than the preceding year means we will never catch up with traffic on those contracts and pay throughout. All I did for that estimate of penalties on tolls was show the fall in traffic for this year then allow growth as predicted by the contract. I did a few scenarios with a few more years negative growth, static and below expected growth naturally the costs to you and I where and likely will be in reality higher.
    • Regarding linking the other major hubs. Sure but have some reasonable options with some reasonable forecasts and build to suit. You'll never get a descent network going for all dual carriageways you'll run out of money. People need to drive to get onto the motorway too, give them descent roads.
    • Safety, the low cost targeted safety improvement scheme run by the NRA targets collision clusters/accident blackspots and puts in remedial work the annual returns on average are 502%. Now that's value for money. At present it gets annual funding less than the money required to build 1km of motorway. I have a document showing a backlog of hundreds of these sites. Yes, that's right many poor roads having collisions year on year not responded to because we're building big roads here and there. Does that mean more people are dying by investing in motorways sadly yes. You do not build motorways for safety you build them for other economic arguments but safety is a nice by-product. But unless you have billions your better off doing something else with your money if you want to save lives.
    • Economics, Value of Time is down that affects the CBA and reduces the benefits and the BCR drops. Discount Rates need to go up in fact for a PPP who is going to lend to a company working in Ireland the risk to the lender of loosing their investment is very high so quoting low discount rates on projects is fudging the issue.
    Look this is taking a lot of time. All I'm saying is with a limited budget road strategy has to change. I have spent significant time on the subject and there is reasonable doubt that present strategy is appropriate. Do not be so hasty to demean another point of view. Those press releases which there are a number, are many hours hard research and they may well offer a good chance for us to get a truly coherent network. But unfortunately it cant all be 4 lanes we don't have the money. We aspired to perfection during the boom now is the time to be pragmatic.

    Again as I stated previously no 2+2 Type 2 Dual carriageway was redesignated as Motorway. If you are aware of such please point out the relevant scheme. If you need to acquaint yourself with the particulars of Type 2 Dual carriageways then please read the relevant documentation form the NRA.

    http://www.nra.ie/Publications/DownloadableDocumentation/RoadDesignConstruction/file,11236,en.pdf

    All inter-urban roads that were redesignated as Motorway were Type 1 dual-carriageways.

    Not quite all, the Cashel and Ennis bypasses were the old style "Standard Dual Carriageway". Type 1 used to be known as "High Quality Dual Carriageway". "Standard Dual Carriageway" does not have a Type xx associated with it.

    What the difference between Standard and High Quality is I'm not sure, but they definately were seperate entities before the Type 1, 2 and 3 classification system came along.

Be a bit more open.

    I will take you up on just this paragraph. Firstly we should not campare UK values for DC and WS2. UK DC is two lanes and a hard shoulder which is Type 1 dual carriageway here(motorway). Do the UK even have a WS2 road type?

    Secondly, of course it can depend on land prices. A road in a rural area will be a lot cheaper than a road being built near a large urban centre. It doesnt take an NRA spokesperson to tell you that.

    Finally, a 2+2 is relatively close the cost of a WS2. Some WS2's in this country are so wide that you could fit a HQDC on it. Also it has so many benefits over a WS2 that makes it worth the extra 5% in cost. We have to upgrade our national primary network first before we look at the secondary and R roads. Do you not realise how much traffic the national primary road network carries daily.

    I'm not sure if the NRA ever actually said this, but the quote is inaccurate.

    Once again, 2+2 dual carriageway means: no hard shoulders, compact GSJs and on-line roundabouts, minimal spec. median, and maybe also reduced lane widths but I'm not sure about that one.

    In other words NOT A MOTORWAY. To stress, I'm pretty much certain that none of the dcs reclassified to Motorway are of the 2+2 type, which was illustrated to you earlier in this thread.

    If you can show me a 2+2 dual carriageway in Ireland that was reclassified motorway, I'll eat my hat - and post a YouTube video.

    True enough but still a very different beastie then a Type 2 2+2 road that's for sure.

    Selective quoting. There isn't a centimetre of redesignated Type 2 as Type 2 cannot be motorway. Indeed there is extremely little Type 2 built as yet, only stretches of the N3, N4 and N21.

I know some of you will be choking on your night-time cornflakes with that one, but its true.

    I'd like to know what data you've discovered/invented on "safety rates", as WS2 is one of the inherently least safe road types around. There is a massively increased rate of fatal, high speed head on collisions on WS2 than there is on other roads.

    The figures get even worse when WS2 roads are grade-seperated for traffic flow reasons. The RSAs "free speed" surveys show this, with free running speeds often *in excess* of that on motorways. Extremely wide tarmac, sliproads and overbridges provide a false sense of security, and lead to situations such as head-ons with 250km/h closing speeds. These have happened on the N17, should you wish to go look at the memorial stones rather than some unreliable figures.

    The only choking on cornflakes is at someone preaching as if they understand road safety and road design when clearly they haven't got a clue

    Except it is

    The UK doesn't have WS2, so I don't know what figures you pulled out of where to further invalidate your already inaccurate analysis.

    Also, UK standard DCs are of a significantly larger profile than a 2+2. More destruction to your "figures"

    I'm not "in the trade", indeed I'm a professional driver and new roads only make my job less stable - due to the massive reduction in journey times leading to jumps in efficiency, my employer has made three staff redundant since 2008.

    Your "work" is faulty and clearly driven by some agenda. You have faulty info, you're repeatedly claiming things which are utterly untrue to be true, and are accusing people who disagree of being "in the trade".

    There is a case for interspersing S2 ( not WS2) and 2+2 sections (because of the gob****e in Micra doing 60kph factor) rather than building nothing but 2+2 or indeed nothing but S2. 20km S2 and 10km 2+2 ...repeated.

    However I am pretty much the only one who has made it around here for roads like the N21 and N5.

    Pure S2 or WS2 does not give sufficient safe guaranteed overtaking opportunities. Mandatory "move over" laws would help in the interim and in future.

    WS2 is not a design standard anymore so how exactly are you reintroducing it then ???

    • The growth data came from all available NRA automated traffic counters with data between 2007 and 2010.

    This data can easily be twisted if certain factors are not taken into account.

    For example, traffic on the old N6 (now the R446) has fallen dramatically since the M6 opened. The NRA traffic counter webpage doesn't seem to be working for me at the moment* but it's probably at least a 70% decline in traffic on the R446 since 2007. If you are including this (and all the other N roads which were bypassed by motorway since 2007) in your calculations then it's giving a false impression of a decline in road usage. In reality, road usage has probably increased on those particular routes (e.g. - if you add the M6 and R446 together).

    Traffic counts on the Galway-Dublin route further East (where the motorway/DC has been open a few years) have been increasing over the last few years..

    There is more capacity on the network now than in 2007 so it might seem like traffic has declined on some specific routes. In my opinion, overall traffic has increased in many regions, and remained constant in some others. There aren't many regions where overall traffic has decreased.

    Gentlemen, Below is an image I hope comes out comparing UK D2AP dual carriageway to NRA Type 1 and 2. There is 30cm, 1 foot, a child's school ruler difference in size on 2 lanes of carriageway. They are practically identical.

    Comparison%20UK%20Irish%20Dual%20Carrigeway%20Cross-Sec.png

    Links to relevant DMRB.

    DMRB U.K. TD27/05, Vol. 6, Sec.1, Part 2, page 4/14

    DMRB NRA TD27-07, Vol. 6, Sec.1, Part 2, Dec. 2007, page 15.

    The NRA DMRB is one large zipped file download.

    Also note WS2 is still on the UK DMRB page 4/14 in above document, so that's that one sorted. Looks like one of us is less than factual in our posting's so far.

    O'Cinneide's paper - I'm showing the math on how WS2 is the better investment direct to the NRA. I spent some time on the phone with one of the NRA people today I think that's the best way of making changes. Trust me it is robust work. MYOB you are in error on all of you're clever counters to selected quotes by me. Just ring the NRA they will confirm 2+2's have been upgraded to motorway. I doubt they would either lie or be factually incorrect. I question the direction they are still taking not their professionalism.

    Sponge Bob's idea on interspersing S2 and 2+2 is very good. The NRA are concerned about uniform driver experience but the UK DMRB state:

    "3.11 Sustaining a particular carriageway standard
    along an entire route is not normally acceptable if this
    is at the expense of foregone economic or
    environmental benefits."

    see, DMRB TA4697 Vol 5,-Sec. 1, Part 3, page 3/2.

    KevR's comment is correct the automated traffic counter system is incomplete so his argument is valid and I concede it. The problem is, there is no other data as up to date. They are putting more counters on the road and when data is up I will happily redo the figures. The CSO is working on traffic figures at the moment. But they too have methodological problems. They rely on odometer readings. As I said, they don't read odometers at the beginning and end of the year on an NCT. the results are a composite of a few years and as such under report changes in traffic when they start to occur. We need many more counters to accurately prioritise roads to be upgraded. In my area with no new road at present to divert traffic and be lost to data recall, traffic levels are down between 20% to 1.7%.

    Things I would like:
    • New traffic growth forecasts
    • More automated traffic counters
    • Review traffic max. traffic capacity for each road type.
    • consideration of a new mid sized road option
    • greater concentration on targeted safety works.
    Talking today to the NRA they are actually examining all the above, already. In which case this becomes a non-issue. If the NRA can adapt to the new situation re funding and economics it would have proved itself in my eyes to be the adaptable organisation providing roads uniformly across the country that we've always needed. I'll wait and see.

    (me been Pedantic)

    There is 30cm in difference between the two driving lanes however there are differences also on central median/hard shoulders.

    Adding up all the measurements you get:
    • UK D2AP= ((2.5m + 1m + 7.3m + 1m)*2) + 2.5m = 26.1m
    • Irish Type 2 = ((3m + 0.5m + 7m + 0.5m)*2) + 1.5m = 23.5m

    So total width difference (including grass verge) of 2.6m (8.5 feet). Or 1.3m per directional carriageway (4.25feet). Little bit more then a child's ruler

    --Edit--

    Type 1 Dual carriageway (Motorway) is 27.6m wide, so difference between it and Type 2 is 4.1m (13.45 feet)

    Come on fellas, the carriageway is 30cm different. Surely you can see the point we need to be developing the whole network not just little bits in a big way. With the present climate every gold-plated project is going to give the Minister of Transport an ulcer. You'll get very little that way.

    And the carriageway is not the land-take.

    Accept it, a UK dual carriageway is not a comparable profile road, just as their single carriageways are not comparable either. You don't seem to be tackling this one, maybe you've realised the gulf is so huge you can't try and explain it away.

    Not in error on a single one, sorry. You're using incorrect data to try and prove a point.

    You are the one claiming (incorrectly) that 2+2s have been redesignated *or* upgraded, how about you ring the NRA and provide details of what 2+2s and where.

    Also, I'd have hoped you'd know that "redesignation" and "upgrading" are two extremely different concepts.

    Using all available NRA automatic traffic counters 2007-2010, traffic has reduced by 6.1%. The trend of reduction is greater year on year.

    Just to be picky here's an analysis of the data taken on the tolled section of the M6 for 2010 vs the traffic counter at Kilreekill (not to far after Loughrea, smack in the middle of the section the toll dodgers use) for 2009.

    Bare numbers:
    147344.png

    On the face of it we have seen a drop in people using the roads in east Galway. But this does not take into account the number of people using the R446. When we add in these figures we see a different story, for the ten months where we have statistics on both roads we see an increase in traffic of 28% (average).

    147345.png

    This illustrates the fact that the traffic data is very incomplete in this country. Does anybody believe that there was about an increase of 30% in traffic in Galway within the space of two months - I seriously doubt it.

    Finally a comparison of N6/R446 traffic in 2009 vs 2010, we see an average 62% drop in traffic on the road.
    147346.png

    I can think of two reasons why there might be so many people on the N6 (NRA generally assumes 75% reduction) without presuming they're all dodging tolls.
    i) L drivers aren't supposed to use Motorways (in my gullibility I'll presume they're law abiding)
    ii) changed driving habits of local traffic (people that used back roads to avoid heavy/slow traffic to go shortish distances using the R446 where they wouldn't have now using the N6).

    From one of the authors of that Irish Times piece you so glibly dismissed. The jokes on you fellas not me

    Using these figures (i know they're not national - i don't have the time or inclination to do that much work for free), you can see why we would glibly dismiss this argument.

    Buddy, the joke is very firmly on you.

    Here are our dual standards. There are 2 x D2M Versions and a Third named D2AP depending on parallel roads

    I am getting a feckin headache with all these different Type 1 ( D2M) and Type 2 ( D2AP) 'standards'. :(

    Like I said WS2 is gone no matter what UK manuals say ....did you ask the NRA about it ??

    Here are the single standards including Type 3 single. Any chance you can do that graphic separately for singles please, it would help a lot. :)

    For the completists Wide Single is now gone and replaced by three standards although the latter one is a 'pilot' and only for sub 5k a day traffic roads like the schemes proposed on the N56 and N59

    Standard ( AKA S2 AKA Type 1 SC) = 3m Verge + 2.5m HS + 3.65+3.65 Carriageway + 2.5m HS + 3m Verge = 12m Pavement and 6m Verge ( probably now Type 1 SC)

    Reduced Standard     ( AKA RSSC AKA RS2 AKA Type 2 SC) = 3m Verge + 0.5m HS + 3.5+3.5 Carriageway + 0.5m HS + 3m Verge = 8m Pavement and 6m Verge

    TYPE 3 Single Carriageway ( AKA T3SC ) = 1.5m Verge + 0m HS + 3.5+3.5 Carriageway + 0.0m HS + 1.5m Verge = 7m Pavement and 3m Verge

    Just ring the NRA they will confirm 2+2's have been upgraded to motorway.

    They won't. If you claim that some 2+2 has been called motorway would you be kind enough to identify the location?
    I doubt they would either lie or be factually incorrect.

    They might or might not, but you seem perfectly willing to be factually incorrect.

    Here is another lot of standards, list from 2007 :)

    http://www.nra.ie/Publications/DownloadableDocumentation/RoadDesignConstruction/file,11472,en.pdf

    Series 000 Road Type and Cross Section
    RCD No. Title
    RCD/000/1 Reduced Single Carriageway (S2)
    RCD/000/2 Standard Single Carriageway (S2)
    RCD/000/3 Type 3 Dual Carriageway
    RCD/000/4 Type 2 Dual Carriageway (D2AP)
    RCD/000/5 Type 1 Dual Carriageway (D2AP)
    RCD/000/6 Standard Dual Carriageway Motorway (D2M & D2UM)
    RCD/000/7 Wide Dual Carriageway Motorway (D2M)

    The same list appears in the 2009 iteration of standards HERE . I pulled the cross sections for all of those designs into the attached PDF seeing as the link there is 20mbit in size.

    Once these are tabulated adequately (absent Type 3 DC which is effectively gone gone along with WS2) and along with the more recent Type 3 SC I specced a few posts back we will then get to the thorny issue of traffic...which is rising along the M6 corridor now the road isn't crap any more :D

    The greens are dreamers. That lake idea is insane. But we have enough roads. Enough. I'd rather see my money being spent on hospitals and schools thank you!

    Here's a novel concept - without a proper transport system and road network (and relative to other developed countries, ours are still some way behind), you do not create good conditions for business, and as such the tax take is reduced below what it could be, meaning LESS MONEY FOR SCHOOLS AND HOSPITALS.

    Think about it....
