Traffic at Deansgrange

Proper infrastructure can alleviate traffic.
They did works, traffic is worse.

The traffic is the same, now it’s just not moving. It’s the lights. I’ll keep repeating it: it’s the lights.

The new road layout is causing most of the probs you had 2 straights in both directions now down to 1 lane in both directions at the lights

This isn’t true. There are no fewer lanes at the Deansgrange crossroads. Movements have been simplified (and they caused massive problems before) and most importantly THE TRAFFIC LIGHTS HAVE BEEN CHANGED.

* Kill Ln towards DL - one straight and left, one straight and right, merging into one lane immediately after the junction.

This was an absolute disaster before, particularly thanks to the right turn into the SuperValu car park, now it’s saner as it’s one straight and left, and one right turn only. They need a barrier divider between the bus lane and the general traffic lane here as motorists can’t help themselves. What they can do about SuperValu I’ve no idea, but logically nobody should be able to turn right into the car park there.

* Kill Ln towards N11 - one straight and left and one straight only (no right turn allowed). Again, merged immediately into one lane after the junction.

Less of a disaster before, as traffic doesn’t have anything ahead to back up with, but it was still always a mess. Now it’s one left turn and one straight ahead.

This could allow the pedestrian phase to be modified to allow people to cross at Clonkeen Road while Kill Ln traffic is crossing the junction on an ahead only light. That would be more efficient than the 4-way stop for pedestrians right now.

Clonkeen and Deansgrange Road lanes are entirely unmodified.

When the council do works, changing the lights accordingly should be done. It probably works on a model alright! So yes i agree!

They changed the lights at Deansgrange corner long before the works to give pedestrians more time to cross and smaller gaps between pedestrian phases. This was a Covid measure. You can find previous threads from much earlier in the year complaining about it.

They modified the pedestrian phase at Bakers Corner at the same time as the recent layout change there, although to my eyes it’s no worse on Kill Lane than it usually was. Pottery Road to Abbey Road is same as ever.

You may only have started noticing the problem because this is basically the first time since then that travel restrictions have been loosened at the same time as schools are back AND at the same time as there’s increased Christmas shopper traffic.

Umm ... okay.

If there are X number of people trying to get down the road at a certain time one day and they don't encounter serious problems, but the following day, the same number of people trying to do the same thing get bogged down in congestion:

1) How is the number of motorists the determining factor, if it has not changed?
2) How is traffic not clearly worse if congestion becomes a serious problem?

You’re conflating “traffic” with “traffic congestion”, is your first problem.

Another problem at Deansgrange is the slip road in front of Supervalu. It seems to be everybodys first choice to park in front of the shops so when there are no spaces the resultant overflow of cars waiting for a space spills out onto the main road and this delays traffic from all directions. Far better to remove one side for parking (nearest the shops) and widen the footpath with some seating and planting. Make the other side loading and disabled bays only and force casual shoppers into the main car park behind Supervalu or the Lidl car park. It is ridiculous to effectively have 3 lanes of traffic on a narrow slip road (2 parking and 1 driving)

So long suckers!!! I'll be at home with a cup of tea and biscuit and you'll still be in traffic.

Cmon now everyone in those cars is elderly or disabled or have been priced out of the Dublin market so have to drive in from Navan every day.

Is there anything at all to be said for reinstating the roundabout at the Kill Avenue, Mounttown Rd, Oliver Plunkett Rd, Glenageary Rd intersection? That way, you could ban right turns into SuperValu, but people would have an easy option to turn around at the bottom of the hill.

That is a huge diversion of about 1km each way and includes negotiating a very busy junction (Bakers corner). Twice!!
I really hate the idea of making roads any wider but to me the easiest solution would be to cpo a bit of the garden of the first cottage beside the Grange pub and possibly a bit of the grange car park. This would at least give enough room for a right turn lane into the car park. However I suppose once there are more than 2 or 3 cars waiting to turn right then traffic couldn't pass anyway.
The Lidl car park across the road is always almost empty. Maybe some agreement
with DLR/Supervalu/Lidl to allow parking there for all users of the village without the fear of being clamped (1 hour free ect)

No because that roundabouts make traffic flow better which is something the absolute mouthbreathers in DLRCC don't realise. It seems they have been on a crusade over the last ten years to rid the county of every last roundabout.

No, roundabouts are good for moderately busy intersections/junctions. As soon as a roundabout gets busy, it gets choked up and becomes gridlocked, so for car traffic the council are completely right to get rid of them at busy junctions (any civil
Engineer/road planner will tell you this). Not so good for bicycles though.

That's an odd comment, I mean aside from what bbuzz mentioned, there are loads of roundabouts in DLRCC.

Which ones have they gotten rid of? The only one I can think of was at Leopardstown/Burton Hall Road, but that was very much no longer working as a roundabout.

Kill avenue roundabout was great, never tailbacks at that junction. Now regular tail backs and extremely slow to get through that junction now. Maybe wait 15/30 seconds. Lights will now cost you minimum 3-4 minutes

Why does traffic modelling software exist then?

no amount of traffic modelling can fit a pint into a half-pint glass. Also, even if your modelling improves the traffic flow, a whole load of people will then think "hey the traffic's not too bad, I'll drive to work instead of getting the bus" and you're quickly back to square one.

Probably because unless your working in town, public transport is useless.

If I was to to take public transport it would be 1hr 15mins.
If I am to drive its 15 mins.
Could I cycle? Yes but I don't fancy arriving to work sweaty and more so i don't fancy cycling in the rain and cold.

When I did go to college there was then the problem of several busses passing because they were full. This idea that people drive purely for convenience is for a large part nonsense. If everyone was to take public transport tomorrow there wouldn't be anywhere near enough capacity but I do agree that we have to try get people out of cars where possible.

The twitter cycling brigade seem to think that everyone should/can cycle which just isn't dealing with reality that many dont want to cycle.
Sadly that bus connects has now been watered down significantly and junctions like these probably won't be adequately improved, cpo for gardens to create bus and segregated cycle lanes should be the priority.

Whatever about bus transport in the rest of the city, this is absolute nonsense as applied to Deansgrange, which has access to the 46A, one of the highest quality bus routes in Dublin.

Been over 6 months since I've been to deansgrange is there a bus lane for the 46a on both sides? Has this bike lane taken away from some of the bus lane?

Are the bus connects plan to create a continuous bus lane on both sides if there isn't already one?

The bus lanes are the same as they always were. I don’t think there’s any space here for extra bus lanes, unless they get rid of car lanes. A bus priority signal at Deansgrange corner heading to DL would be a useful addition.
