Cops on the N3 this evening cop on!

Naimless

Do the cops know what sort of traffic tailbacks they cause on both north and South bound routes on the M50 today due to their two speed camera vans parked nose to tail on the hard shoulder on the N3 roughly where the old Quinn direct building was, total gridlock up until that point on the road and a total waste of time of resources.

Why not park these vans in separate locations on secondary roads, I can't imagine they recorded one car going faster than 5 miles per hour this evening.

The 100km zone beside Liberty? Been there quite a bit lately. It must be easy pickings if they're there that much.

If people jam on, like lots seem to do when they see gardai or speed vans, they're the ones at fault, not the gardai.

Some people become imbeciles in the presence of speed traps or gardai.

Yes but the traffic was stopped on the m50 due to them, isn't that more dangerous.

Flash for cash vans dont care about traffic jams until the revenue they take in drops then they will move to another shooting fish in a barrel location.

FLASH 4 CASH

Should all be fitted with these signs similar to we Buy cars 4 cash.:pac::pac::pac:

These vans should be outside schools and roads that are dangerous especially where lives have actually been lost.

Money should not be going into a private companies pockets and should be better spent on improving actuall defective road designs and conditions.

I agree, but this behaviour is common knowledge so why bother not catching anyone speeding and pissing everybody off?

Problem is people will hit that road at 120kph as they think no one will be there, and it'd work for 10-15 minutes.

After that its pointless.

The limit at the Quinn building's 80, off the top of my head. It doesn't go to 100 until just a little later.

Barrel, Fish, ETC.


Was.... ahem... testing some modifications to my car recently and was doing a fair bit of speed on the M3 to get the RPM up to check for misfires.

That explains why everyone was creeping in on the way in this morning. Normally everyone shoots by me on that stretch!

Also, the schools are back. The difference it makes on that road is staggering. Something like 15 minutes on the journey to cabra.

Sure it doesn't bother me, once I'm in for half 7 I'm happy

It goes to a 100 around the old junction for Blanchardstown Village, so it's a 100 before the Liberty building.

I agree, though it was interesting to see Mythbusters showed that a single car doing that can cause tailbacks so it does not make many idiots to cause issues.

It doesn't go to 100 until just after the last junction for the centre, where the crown plaza is, so it's still 80 at the Quinn building.

I'm pretty sure that's the old limit, it becomes 100 before the building now.

Edit. Wrong road

Well one thing's clear, it doesn't help if 2 people are sure it's a different speed around there.

It shouldn't be so trivial, but I've seen that as an issue on loads of roads.

Its a well known phenomenon, and believed to be the most common cause of stationary traffic on the UK motorway system.

You can see this every single day on the N11. You get idiots panicking at Bray North and Fassaroe, which brake and it starts to ripple. I've often thought if you rigorously enforced a lower speed limit (Like a staged decrease from Cherrywood to the M11/N11 interchange) and a minimum car gap, you could avoid it. You can cruise through that section without touching the brakes if you just leave a gap. People drive too close, simple as. And then you get people hopping lanes, going no where. From driving it for close to 10 years, I can categorically say neither lane is faster. So I don't understand the burning ambition to be in lane 2.

It's a very interesting phenomena and it boils down to the first driver coming to a complete stop when there is no need for it. It's easily visible in the Nagoya experiment clip a couple of posts above - once one driver has stopped everything goes downhill, as each following driver will not only stop, but wait until the car ahead has pulled away significantly before restarting.

It's quite a bit of a conundrum, reading a bit about the possible solutions the "minimum distance between vehicles" idea has been kind of scrapped, as it would result in the same number of cars taking up more space on the motorway. In a nutshell, the traffic jam would be moved - from the motorway to the feeder roads, as cars trying to join would have to wait because there is no space for them.

The only real mitigating factor seems to be driver training and awareness - simply managing speed fluidly, avoiding slamming on the brakes for every little thing would help immensely. Making that understood...well, good luck!

It is worth nothing that slight and heavy braking also cause tailbacks according to the experiments, not just coming to a complete stop.

I know all about it....

But it's difficult to leave enough space because the moment that twat driving next to me see's the gap he/she/it swings right in leaving me dangerously close to a car yet again.

Hate the N11, what a failure of a road.

Exactly. And once again, no difference in lane progression. Neither lane is 'faster' I can testify to that. But yes as soon as they merge from the N11 at the M11 interchange, its straight to lane 2 and .... brakes!

Drove by yesterday, the 100 limit kicks in at the exit for Blanchardstown village at the Garda station so it's before the Liberty building.

Yep, you're right, checked it today myself, my bad. Very odd for them to move it back to the village exit.

And then it goes down to either 60 or 80 just further up until the M3, redicious system and same with coming of the M3 onto the duel carriageway. I think it's something like 120 - 60 - 80 - 60 - 80 and that just as far as the hospital.
