First Glow-In-the-Dark Road Debuts In Netherlands
An anonymous reader writes "A 500 meter (0.3 mile) stretch of road in the Netherlands has opened without the standard crop of streetlights lining its perimeter. The streetlights are believed to be unnecessary since the road markings were painted on with a mix of photo-luminescent powder, which absorbs sunlight during the day and radiates a portion of that energy back at night. Whether the modified road paint can withstand harsh weather or even provide sufficient lighting given insufficient exposure to sunlight during the day remains to be seen. The project was orchestrated by Studio Roosegaarde, which in the future plans to implement weather-sensitive road markings that would inform drivers when outside temperatures drop or rise above certain levels."
You took too much, man...
We already have retroreflective paints. Road markings and signs illuminated by headlights are clearly visible. On the other hand, some things (like animals and pedestrians) require some means of illumination at night. Streetlights are OK, but headlights are better. An animal or other obstruction will only appear as a shadow against a glowing roadway.
Have gnu, will travel.
All the pictures in TFA show illumination from headlights.
These aren't the first, they've had glowing roads in Fukushima for nye on 3 years now!
*ducks
Most animals and plants who live alongside the roads will love this. Finally they can sleep in the dark!

Right. Also, this cant work on overcast days . I really don't see the point of it . I'd say they'd rather invest that effort on headlight technology
this is awesome
All the "pictures" in TFA are computer renderings. For a road that, apparently, has already been painted you'd think they could have taken at least 1 photo of it.
I used to live in the Netherlands, and I can confirm winters are cold and dark. Days are not very bright either. So an eight hour life (yes, I RTFA) for these very cool glowing roads is not going to cut it - nights comprise 16 hours of darkness in midwinter.
It should work well in the summer, when days are brighter and nights shorter.
But I think a backup is required, destroying the whole point.
But it does look very cool, doesn't it?

Those of us who don't live in cities have been driving fine at night without streetlights forever. No special paint needed. Cars have headlights.
This space intentionally left blank
I'm reminded of the Road Runner cartoon where the Coyote paints a stripe that leads off the roadway and into a rock face. Let's hope no one in the Netherlands both enjoys our cartoons and has a mischievous streak.
there is a video of the road on dutch television. video of the road
It does look quite nice!
...but the "Autobahn" in Germany never had any kind of electrical lighting (besides retroreflecting paint for the road markings) and even at night large parts of it are considered save enough to not have speed limits - even at night!

Here in the southern UK we've had solar LED road studs for years - they are used on some A roads and mark line dividers, road edges and turn-offs in place of the usual cats-eyes. Work pretty well too (though I find them a bit 'stroby', like some vehicle brake lights).
All your ghosts are just false positives.
I guess that with this paint one is able to see the edges of the road more clearly, but I don't think that was ever a big problem with "just" retroreflective markings.
I think, that the light from these new markings will only blind you from things just beside the road (think pedestrians, cyclists and animals) which you would probably see better with just the headlights without something shining in your face. I mean try to see what's behind someone holding a flashlight in the dark. More light from the road surface will just prevent you from seeing the darker contrasts. That's why street lighting is installed above, not on the sides of the road, or on the road itself!
Some people also insist they see better when driving in the dark with their fog lights on... Yeah, you'll see the road surface right in front of the car better, but the extra light from the road just in front will only blind you from things further away, taking away your chance to react to something unexpected further down the road.
I think these markings are no replacement for street lighting and will simply just cause more accidents. For savings, it would be better just to turn off the street lighting and leave the existing markings as they were.
The Dutch article (http://nos.nl/audio/634119-het-lijkt-alsof-je-door-een-sprookjesbos-rijdt.html) has a low-res picture of it. The thing looks like a video, but is actually an audio fragment, but the picture is an actual picture of the 500m stretch of road.
Oh, wait, humans can actually see by starlight alone.
Not if you have headlights on, are you supposed to turn them off when you hit this stretch of road? And park for about fifteen minutes to dark adapt?

Keep in mind that this guy is an artist first and foremost. The point of the glowing stripes is as much about how cool it looks, as it is about road safety.
but this isn't one of them...
If you want to emulate the impressive road safety and convenience of roads in the Netherlands, copy the good stuff, not the hyped stuff.
A simpler solution would be to just let all the genetically engineered, glow-in-the-dark lab animals out in the wild. The roadkill will light up the roads.

I don't think it's actually in use yet. It's still being set up.
Tourists who have no idea, who came to amsterdam to take shrooms, and they step out at night and see glowing roads and think they're totally tripping...
Forgive a potentially stupid question, but how is this going to work with snow on the ground?
I believe there are many roads in the Fukishima area that glow a pretty blue-green.
Scruting the inscrutable for over 50 years.
Mainly because they don't work as well as is claimed. Having a couple of dots of light every few metres isn't nearly as clear as having glowing road lines. I suppose however in their favour the eyes last much longer.
Another issue however with cats eyes is the effect they have on tyres. Its conveniently never mentioned by the govn but driving over hard lumps of metal in the road - even if they do squash down a bit - at high speed over the years when changing lanes will wear out your tyres faster and can I suspect even cause failures if the tyre is already on the verge of going.
I dunno if it's in TFA (who reads it). But if it's cloudy the paint will be loaded by electricity I heard in the Dutch morning news Wakker Nederland.
the special thing about the paint that if they put a small current trough it it actually starts emitting light so having dark days doesnt matter anymore
Road side illumination should be generally restricted to built up areas and be more about restricting nefarious activities rather than traffic safety.
Also, where ever practible, around on- and off-ramps.
I personally don't see the point in having lights on most highways given that cars carry around their own illumination, and going straight and changing lanes doesn't need too much effort without lamps. But given the shuffling about just before, and just after, ramps, it's worth spending the resources to improve safety.
For the rest of the length of most highways (even those through urban areas): meh.
Seeing as how all of the light is directed upward, this adds to light pollution, which some people blame a lot of problems on: http://darkskyinitiative.org/
"I'm so moist I'm sticking to the leather." -Kermit the Frog on The Late Late Show
This blog extolling Dutch road design innovation is nonetheless quite dismissive of the "glowing paint" idea, and mentions the use of glass bead retroreflectors (as in the UK) as a much better idea. It makes a good case.
Starships were meant to fly, Hands up and touch the sky - Nicky Minaj
Instead of using luminescent paint for the lines, why can't we imbed piezoelectric crystals into the tarmac that would generate light from the mass of the vehicle. That way you'd see this glow where the cars are.
There are countless miles of roads in the UK that don't have street lights - even motorways and A roads - and although this paint might only glow for 8 hours, if it improves the safety of those roads for 8 hours longer... isn't that a good thing? Also, a lot of street lights in the UK are switched up during the middle of the night.
The main problem I see is that roads aren't well enough maintained... paint wears, is patchy and in many cases disappears entirely for months before being repainted.
A see a lot of you guys going "oh, well this is very good blah blah blah".... I guess it really is cool to hate.
Nice idea, but what happens when it snows?
Someone posted a video link above. Not karma whoring, so I'm not repeating it here. If you want an actual image of the actual road, look a few comments further up.

Note to self: When trying to sell a product, probably should not associate it with "radioactive".
> Roosegaarde told Wired.co.uk that Heijmans had managed to take its luminescence to the extreme—"it's almost radioactive", said Roosegaarde
"Whether the modified road paint can withstand harsh weather or even provide sufficient lighting given insufficient exposure to sunlight during the day remains to be seen"
So the standard US policy of making a 1 mile test strip didn't quote make it over to the Netherlands? They just threw it on 500 miles and said let's see if it works? Genius.
Streetlights are OK, but headlights are better. An animal or other obstruction will only appear as a shadow against a glowing roadway.
Headlights are not better. Of all the directions of illumination, that from below eye level, and especially from directly ahead (as oncoming traffic's headlights are), is the least effective. Why do you think that football stadiums are floodlit from high towers and not from knee level? Aside from the fact that fixed lighting from grid power is more efficient than car headlights (in the sense of lumens per energy input) where the traffic is continuous, as in towns.
As for obstrucions appearing "as a shadow" - that's bang on; it is how street lighting at one time worked by design. Sodium lighting was of a wavelength that was relected by "black" asphalt and roadside masonry, so the background was actually quite a bright yellow. Unlit objects, which generally reflected sodium light less than the road, then appeared clearly as black shapes against that background. Vehicles, in turn, formed a dark foil for their own side lights (ie running lights, not headlights).
Given that, in the UK headlights were once only used on country roads where there were no street lights. I remember driving back then in London and could even see cats or dogs crossing the road at night 800 yards ahead. Anyone with headlights on (perhaps after coming from an unlit road) would be angrily flashed at. That "system" was destroyed however in the UK by a period of patchy electrical power cuts when drivers just left their headlights on rather than bother to turn themon and off as they went in and out of lit areas. Not using headlights all the time became frowned on, and now there is no chance of seeing a pedestrian crossing the road from the opposite side behind a barrage on oncoming headlights, until they walk into your headlight beam right in front of you.
They did, but all the pictures were over-exposed.
Don't fight for your country, if your country does not fight for you.

I collect glow-in-the-dark things. So excuse me as I book a flight there.
Hope my pickaxe can be considered carry on. Going to need a lot of KY for the TSA screening though.....
Yes, finally, my childhood come to life. Many an hour was spent making car sounds vroom, vroom, errrick (curve), vroom with my cousin with our Glow in the Dark Matchbox cities.
The idea of including weather info into the roadway (or perhaps a heads up display...) sounds interesting.
Just think it would be better in a heads up display than on the road.
Thanks for a great childhood memory.
