Turns Out Glow-in-the-Dark Roads Aren't Working as Planned

By Tom Pritchard on at

Remember those glow-in-the-dark roads we talked about a couple of weeks ago? Well it turns out they didn't work out so well, with a less than satisfying performance during the first public trial.

The science behind the lines is sound, the lines absorb ultraviolet light during the day and then emitting a healthy glow at night. The problem is that they aren't being consistent with the amount of light they're emitting. Even worse, if there's heavy rain they don't emit any light at all, making the whole endeavour completely useless.

Fortunately Heijmans Infrastructure, the engineering firm behind the idea, are already hard at work creating "Glowing Lines 2.0," which will be seeing widespread testing this summer. [Engadget]
