Query about which lane to be in

Delirium

Hi folks.

Have a quick question about lane positions. I've included a pic to hopefully help illustrate my query.

Basically, my understanding is that a driver in lane A should only be exiting onto either lane 1 or 2. while a driver in lane B should be exiting on either lane 3 or 4.

There are no signposts on the road with lane A and B. The two lanes have the following road markings. Lane A has a turn left road marking, while lane B has turn left and straight on road marking.

I'm basically looking for opinions from the forum as to whether my understanding of lane positioning of this junction is correct.

That would make most sense! as both have a left turn painted on them.


its a mess of a junction in fairness for your typical Irish driver.

where is that junction op?

Delirium

sexton street, in Limerick. Have to drive it every day to work.

I'm in lane A for lane 2 and at least twice a week some git cuts across from lane B into lane 2 :mad:

If marked with a left turn, then lane A would only be for the hard left turn (lane 1).

To go to lane 2 or 3 one would approach in lane B and indicate immediate on passing lane 1 and carefully maneuvre over to the required exit lane 2 or 3.

FOr lane 4, stay in lane B and keep right of traffic maneuvring for lanes 2 & 3.


Is that the junction heading into Donnybrook in Dublin ?

you could find it in google maps and post a screengrab of it or link to it so people could get a proper look at the road itself and the road markings to better decide, but from what you've said and the drawing, i'd be in lane A going left only onto road 1 given that lane be is also left, they *might* decide to use lane 2 or 3.

as for who is actually in the right, you might as well flip a coin as half the people here will say one thing and half will say the other and will pretty much do as they please either way.

Delirium

Tried google maps vibe, but it's out of date. the road with lane A+B was converted from a one system in the opposite direction to the system that I've attempted to describe.

I'll see if I can get a grab of the junction that opens onto the four lanes.

Delirium

Ok, I've got some pics. Obviously the first pic is missing the new road markings, but it'll give you an idea of the approach to the junction.

#1 - the junction has traffic lights now in place as you approach it



#2 - just as you enter the junction. you can just about make out the 3 lanes to the left.



#3 - a view of the 3 lanes as they appear



hope that helps give folks a better idea of the junction.

as usual its the sloppy roadmarkings and signs to blame here. I can see how someone would go from lane B to lane 2 and think its was OK...it's not actually wrong, although ,from the evidence you give, I would follow the course you are taking.

Just seen your pictueres and now think the opposite! left habd lane would seem logical to me to turn hard left ortherwise you would be at the yield at a verty strange angle

I would say A -> 2, B -> 3. But i can see where the confusion might arise, car in B might think your hitting for 1, turning left proper.

Gamy junction!

Typical Limerick City road layouts. They really need to start closing off some streets, and looking at a total redesign of the traffic flow in and around the city as a whole. As usual they'll 'tinker' and mess the whole thing up.

oops. Sorry, corktina, I forgot to mention, the junction has traffic lights.

Just in case that makes a difference.

Lanes 2 and 3 are almost a straight on option and your diagram is not too accuarate. The more I think of it the more I think that lane A should be marked left turn only with a 90 degree arrow and B marked with a 45 degree and stright on arrow.

definitely agree with that idea for the road markings. that'd end a lot of confusion in the junction.

or indeed lane A could be marked with both 90 and 45 degree arrows in which case your method of negotiating the junction would be correct.

This would be my thinking on it.
That someone in lane A should be going left only, and lane B then is for people going "straight", except for the little left-right shimmy.

It would make more sense to have a big sign with a diagram showing how the junction is supposed to work, or realign the road so that it's more of a standard junction with left, straight and right, than that haphazard yoke.

Delirium

appreciate the opinions, guys. Looks like I'm in the wrong lane then:o

There is a big sign about the 3 lanes once you enter the junction, but none telling you the lanes to be in. It's a best guess situation based on the markings.

Based on the posts so far, I guess I shall start using Lane B.

What route are you taking? What road, by name, are you coming from and what road are you going onto? I'm familiar with the junction but am hugely confused by your sketch of it.

edit: should 1, 2 and 3 be parallel for the short distance between sexton street and the top of roches street, with 1 turning onto parnell street and 2&3 turning onto roches street? That might be what threw me.

yeah, didn't draw the turn onto roches as I'm only concerned with the junction. Once I'm in lane 2, I know what to be doing next

It was more about lane 1 branching off to the left that threw me. The junction layout becomes more simplified than your drawing then.

- No right turn
- Straight ahead onto one lane (4) so right lane (B) only
- Left turn, 2 (A&B) lanes into 3 (1,2&3) so really A is exclusively for 1, B is exclusively for 3 and 2 is up for grabs between A&B

If you consider trafic flow in two lanes from sexton street onto roches street (probably the biggest volume through the junction most of the time), it should really be A to 2 and B to 3 and that's how I would do it. However, if most of the traffic in A is going to 1, then 2 is up for grabs from B to increase the throughput of traffic through the junction, though if that was me, I'd always yield to anyone travelling from A to 2 before potentially moving from B to 2.

In summary, its a ****ing mess.

Delirium

Pretty much how I was treating the junction.

Only problem is that lately quite a few drivers don't check for cars from A before moving into lane 2 from B.

If you look here, the black line leading from the centre of sexton street through to roches street seems to indicate that this was designed as the through route, with lane A to 2 and lane B to 3.

Delirium

Thanks for that. It's a much better diagram of the junction than my own effort.

corktina

I dont actually think you are in the wrong lane...but nor is the other guy! Poor Irish junction signing as per usual.
