RE: Glow-in-the-dark roads coming

The glow in the dark markings seem largely inconsequential, wouldn't hurt anything that I can think of but wouldn't help much either.
The other bit of this however:
1)Snowflake symbols 'turn on' by hitting 4 Celsius or whatever the chemical threshold is set as.
2)Traffic flow across the affected area instantly reduced to 10mph.

1)Snowflakes symbols painted on the road are slippery when wet like all other paint.
2)Traffic stopped every time it rains because of another motorcycle crash.

Our road markings are already sort of glow-in-the-dark. Not to the same extent but they do reflect light quite well already, the paint is full of tiny glass particles and other reflective material, so the idea is essentially already in practice and has been for about 50 years now.
Only if you equate reflecting light to emitting light.

Over in Germany we were in an area where they were trialling an LED system that was red on the left verge, white in the center lanes and green on the right verge. When the temp dropped below 4 degrees the white leds turned blue and in the event of an accident or roadworks they would go yellow. Very guicci indeed.
Typical Germans!Take a simple idea, engineer it to....work.
It would never work in Britain. We would have to over engineer it to flash a message at the driver directing him to the nearest shopping centre.
My goodness, snow flakes on the road?!
At least that won't be a distraction and divert attention from actual road markings. Don't most people have an external temp display on their OBC? (I drive an '87 3-series so I don't, but most will). Surely the weather forecast is enough?
The LED cat's eyes are a good idea provided they stay lit on overcast days and with weak UV i.e. most of winter and when the nights are longer, but I really thought glow in the dark stuff stopped some time in the 90s.

I have wondered for a long time why 'we' simply dont use reflective glass beads/particles in the center white line paint

seems other countries road authorities do
for that matter how would a proportion work in the asphalt....permanent and would reflect headlight illumination

If we use any glass at all on english center white lines we dont use enough glass to make the white lines reflect enough light....typical govt cost saving approach for something that costs bugger all Turning the street lights off to save money you say – I wish they would.
Our council have recently decided the best use of ratepayers’ money is to change the perfectly adequate orange streetlamps for new white ones. They’re spending loads of money to make the roads less safe.
When I was driving down the twisty empty road near us late at night, any white light I could see used to mean a car was coming in the other direction. Now there are so many white lights along the long twisty road I don’t notice a car coming in the other direction until much later.

i have often thought that it would be fairly simple just to paint the kerbs
Usually seems to be in warmer climates than ours though, I don't if that's as simple as mud sticks but dust blows off.

I remember reading about them trialing these in the uk some years ago, I assume that "they" decided that there wasn't enough benefit to it to roll them out.Gassing Station | General Gassing | Top of Page | What's New | My Stuff
