Blog post: swansont: Glow in the Dark … Roads

The studio has developed a photo-luminising powder that will replace road markings -- it charges up in sunlight, giving it up to ten hours of glow-in-the-dark time come nightfall. "It's like the glow in the dark paint you and I had when we were children," designer Roosegaarde explained, "but we teamed up with a paint manufacture and pushed the development. Now, it's almost radioactive".

 

Special paint will also be used to paint markers like snowflakes across the road's surface -- when temperatures fall to a certain point, these images will become visible, indicating that the surface will likely be slippery.
