I’ve unlocked the segment (and the two other segments that are attached at the same point), but it’s inside a junction box, so it’s only possible to move it a couple of metres northeast without deleting and re-creating the junction box.
If it needs to be moved more than just a couple of metres, can you say when the bollards start? Is it at or before the yellow box that you mentioned?
They do start there, yes, so outside the current junction box. So only at the non-continuous line if you look at the satellite imagery (you can just about make out some bollards there, with the shades that they cast; it’s more up-to-date than streetview) it’s possible to move to the left-turn-lane.
It’s better then it was, there were even bollards before the keep-clear box, so driving up to that intersection if you wanted to turn left you had to really aim for the gap, I’m still surprised by myself that I got that one right the first time :lol: At least they removed those bollards now (or perhaps someone ran them over). But that’s not relevant for the issue at hand.
Is it too much trouble to recreate the junction box? I can drive down that road with Waze on, to see what instructions I get, if you want?
Off-topic: I have also sent you a couple of private messages. Did you get those?
Just tried, I can change it. But given the fact that you said it’ll affect the junction box, I’m not comfortable hitting ‘Save’.
This is what it should look like (with the red dot indicating where A originally was):
The only way is to re-create the junction box. The reason I’m avoiding doing that is because it controls the entire junction, in all directions, so you have to take note of every possible route through the junction and all the lanes for each route, then delete the junction box, then re-create all of those from scratch. That’s an unfortunate flaw with junction boxes.
I’ll give it a go later on, once I’ve done enough work with the day job to keep my conscience happy
Another possible issue on this intersection is that the current set-up allows a u-turn on the N11. Is that actually permitted? I didn’t sit my driving test here so I might not be fully aware of all Irish regulations. My wife is saying it’s only allowed when actually indicated (such as the horse-shoe shaped lights elsewhere along the N11).
If it’s not permitted unless indicated, the same issue would exist on other intersections of the N11, as I keep being sent back when I ignore the route Waze has set out for me, by way of u-turns.
The reason I’m saying this now is because I see that a U-turn on the R113 is disallowed.
I did my driving test (cough) 32 years ago, so what I faintly remember is probably out of date … however, I think U-turns are generally legal unless explicitly forbidden by a sign. I think the signs elsewhere on the N11 mostly appear where there’s a lane dedicated to U-turns.
I guess any manoeuvre is forbidden if it could be considered to be dangerous, but that’s a matter of judgement. I just had a look at this junction in SV and I didn’t see an U-turn signs (forbidding or permitting) in any direction, but it’s interesting that the JB here allows them on the N11 but not on the R113. I’m not sure why that is - I’ll ask for opinions in Slack. The SV images here are two years old, so it’s possible that signs do exist now.
We just talked about this, and it’s probably better not to move the node any closer to the northeast. The “turn left” instruction combined with the lane guidance on screen should provide a decent amount of warning to move left.
Perhaps more importantly: if the node is placed too early, then the lane guidance shown to the user will disappear and the user won’t be able to tell which lane they should be in as they approach the junction. I think this is a bigger hazard than the risk of getting to the left of the bollards in time.
There’s a good point in that too and I think most people get it right anyway. We drive there regularly and I’ve seen only one car turning left from the lane to go straight, but they were probably just not paying attention and against that no lane guidance can compete.
Regarding u-turns you’re probably right. A u-turn on the R113 is way too tight, you’d need the whole road and that’s just too dangerous. On the N11 however it is doable (as proven on a daily basis) and the dedicated u-turns are only there where there’s no right turn.
Screenshot of the lane guidance and a photo of the view through the big glass viewport screen in front of my face, where you can see the bollards. Funny thing is, because the road splits anyway (to reflect the separation in segments in each direction (even though in reality the lanes aren’t separated)) it kind of looks like you have to keep left quite early.
