Question re: Bicycle Traffic Lights

These have sprung up all over the place in the last year - there's loads of them on the Grand Canal on the junctions. I never saw anything official about them, they just appeared with no instruction on how they were to be used.

I did a bit of digging/googling, and came across something somewhere (can't now remember where I saw it) that those high bike lights are intended for cyclists who are using the footpath (ie kids) to cross safely when the green man is lit for pedestrians.

The ones where you have the blue box are the ones intended for cyclists on the road/cycle lane (if they're fitted).

As I say I can't remember where I found that - it sort of makes sense if you squint at it, but lord almighty, you'd think if they're introducing a new concept like that they'd have a bit of an information campaign about it.

I see a lot of cyclists who definitely think it's a green for them, and they're nearly taking out pedestrians crossing on their green man as they shoot off.

Here are two more examples from the junction of Lower Kilmacud Rd and South Ave. I can't see how you can use them without breaking the law. I doubt much thought went into them.

That light is solely covering pedestrians/cyclists crossing footpath to footpath. Quite possibly the ones covering the rock road crossing would be green too so the other cyclist was wrong to continue.

As posted above it's more for kids sharing the footpath with pedestrians to cross safely. If you're on the road the normal road red traffic light applies there.

It's highly unlikely that DCC have put up infrastructure for a footpath to footpath cyclist crossing when cyclists are not legally allowed to use the footpath. My assumption is that it's there to facilitate people that are waiting to rejoin the Rock Road inbound having been in the cycle track on the other side of the road. It doesn't make sense that they wait at a red light at the end of the cycle track only to shuffle to another red light in front of traffic on the road.

But what problem is it solving then? Was there ever really a fear that hundreds of kids sharing the footpath were being/ would be left stranded for hours at a time because of uncertainty as to whether they were allowed cross on the green man? I mean if they're already using the footpath while cycling is it not reasonable and safe to also assume that they're not concerned about whether they should be proceeding as they would if they were a pedestrian?

Just another example of the half arsed approach to "cYCliNg InfRaSTuCtuRe" in this country

They’ve done the same at the junction of East road and the East Wall road, similarly it’s a pedestrian crossing with a set of bike lights even though there’s no bike path on the side of the road you’d be crossing from

The dropped kerb does not extend to the full width of the area between the white lines on the footpath. Somebody is going to hit that kerb with their front wheel and they'll crash. The built infrastructure in this country is such an embarrassment.

EDIT: I have reported it to Dublin City Council.

(Some junctions with the cyclist and pedestrian lights on what was originally just a pedestrian crossing go so far as to have a shared space sign on the footpath leading up; the one crossing Sandyford Road to get to the Slang cycleway has this arrangement.)

Similar lights here in Santry. Im usually stopped on the road (the cycle lane is crap!). If the main Light goes Green… i move (im heading towards Dublin Airport from Santry). If the cycling light goes green, i proceed with caution and allow any pedestrians crossing to do so.
