Mildly Interesting

I'm pretty sure the real reason it's projected is so it doesn't get covered by snow in the winter. At least that's the reason for projected street signs elsewhere in Finland, such as in Oulu.

I wouldn't say this is for zombies or people who forget that the team has the right of way. This looks like an exit from a building, which leads directly over tram tracks with no sidewalk that ends or anything - to me, that's an accident waiting to happen. Sort of like if you would put a street there with no sidewalk in front of it, that would be similarly dangerous.

Oh that's Espoo near Sello? I go there often and have noticed the same thing. Tampere also has started projecting red lights as a line on the ground on the crosswalks near tram stops. I think one reason is the snow covering painted signs on the ground as well; the struggle every winter to figure out where there bike lanes are is real :/

And that line of irregular, seemingly-bumpy bricks is for accessibility for actual blind people.

In metro (subway-ish transport) stations over here, there is a line with differently textured tiles, which are also painted yellow.
They feel different to step on even when wearing shoes, so it would presumably help blind people know when they are stepping outside the walkable area.

I saw a bunch of projected signs like this in Finland that were used for marking bike paths. Projections mean that the markings are still visible even in thick snow (I saw a few people cycling through knee deep snow. Finns are absolute madlads, even by Nordic standards). They're useful because even when paths are cleared (which was impressively thorough — the vast majority of paths had been ploughed)

Stuff like this is why I love travelling — I'd have never thought of the issue that regular snow would cause for road markings, nor would I have thought to solve it like this.

IKEA also has this, at least in the one I used to visit.

Given that they're for navigating indoor hallways, though, they're probably not meant for inclement weather.

Do NOT wear noise cancelling headphones around traffic. That is a massive safety hazard.

I like this idea for a lot of reasons. The inclement weather one I see in the comments is definitely one of them.

But it also puts me in mind of some of the clever ways I've seen posts and reflectors used to give the impression (when say you're driving at night and only see them out of the corner of your eye) of a person standing there, until you look at them properly and then they look exactly like what they are.

There's one in particular in a neighborhood where I used to live that to this day if I drive by it, my hindbrain says "HUMAN" and I really don't understand why because the post looks nothing like a human when I look at it properly. It's magic.

Reminds me a bit of Australias (Sydney?) projecting giant Stop signs on water curtains in front of trucks that ignore all the other warning signs that they’re about to enter a tunnel with low ceilings.

It's just a better solution.

Surely a fence is the better solution here
