Yellow signs, black triangles and squares

traco

Can anybody tell me what this sign means. They are located on N4 and exits off the M50. There is also one with a black square. Are they an alternative route sign?? No mention of them in the latest Rules of the road book.

quadrifoglio verde

Yep there alternative route signs for when the m50 is closed.
Overhead gantry will flash up with the symbol to follow to get to the open part of the m50 and you just follow them

Would a television advert be a good idea?

Most motorists have no idea what they mean

Difficult to organise a tv advert within a few minutes of an accident - also TV advert covers the entire country - waste of money doing it as an infomercial for a local diversion especially as TV advertising is hugely expensive and does not cover a large number of people these days.

When it happens there will be radio announcements within a couple of minutes on all radio stations. Even if you are listenenting to a cd, the chances are you will tune in to a radio station or check aa roadwatch or read the overhead gantries which will all have real time info.

In addition, with many people seeing the signs, they will also query it (as per OP) and after a while, many will know what they are for.

I think he means a preemptive advertisement showing people that these things exist. Just because we have noticed them it doesn't mean others have.

And "culchies" have been known to use the highways and byways of the Pale from time-to-time.

I meant to outline the principle of the sign (like those RSA infomercials).... 'if you ever see this sign, it means diversion'.

I didn't mean an advert for every single diversion. Ha ha

They are very recent too, so not surprising that not many people have heard of them. I guess they could be built into an information campaign covering a number of issues rather than just by themselves.

it doesn't need advertising, just a sign at the start of the diversion saying to follow .

No need for a campaign, where ever the diversion starts its explained.
If you come across a sign on its own whilst on a different route then its not relevant to you.

And I'm a culchie but I remember these signs from when I lived in London over 20 years ago;).

My understanding is that their primary intention is to redirect emergency services around an issue rather than the general public. So the overhead gantries will show the symbol in order to alert ES on that route, but you won't hear AA roadwatch or any radio stations telling motorists to follow the triangle marking.

savagethegoat

no you are wrong, they are to show the alternative route to general traffic when there is a road closure.

A few months back when there were issues at a couple of point on the M50, A lot of people didn't know their way around it to divert themselves.

It's to re-route them around closed sections. There's different symbols for each junction being diverted away from in both directions.

My only concern with it, is that I'm unsure if they've been able to pick the best route to get around the toll bridge.

You have to approach new knowledge with the expectation that no one knows what you are on about. Flashing a symbol on a notification sign is going to mean nothing to someone who doesn't understand the purpose of the symbol.

I live on a route that had those signs put up months ago and eventually figured out what they were for.

But Dublin City FM do direct people to follow them when there is either an accident or massive delays on the M50.

The Backwards Man

I'm a culchie too and I know what they are.

We live out here because we're mad, not because we're stupid.

The first sign where the diversion starts gives you the destination and the symbol to follow (usually the next junction down if a motorway)
It doesn't have to be an overhead gantry either, it could be a simple printed sign.
The big problem is people don't read the sign and then end up in some unfamiliar housing estate not knowing where to go.
It couldn't be simpler a bit like Hansel and Gretel following the bread crumbs home:D

the picture above and the sign are different yes they both have a triangle one has a triangle with one of the sides vertical and a black border the other is a triangle with one of the sides horizontal how am i supposed to know that both signs refer to the same thing?

biko

Added a poll. It would be interesting to know how many don't know what this sign means.

zilog_jones

There have been similar signs around the Limerick Tunnel for a number of years.

They're not the same thing. That "M1 North closed" sign is from the UK.

you just follow the sign that is the same. Each route will have it's own symbols... triangle, inverted triangle, square, circle etc.

does it matter? you read the sign, you follow the symbols...not much to know is there.

Alkers

There hasn't been much publicity around them yet as they haven't been rolled out for all of the M50 junctions yet.

traco

I was guessing they were an alternative route alright but be nice if they actually had the info formally available on their website to clarify intended use etc.
