An anonymous reader writes: The Netherlands is moving forward with plans to build "smart" highways that can become more easily visible or communicate weather conditions to drivers. Work will begin as early as next year. '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. Roosegaarde says this technology has been around for years, on things like baby food — the studio has just upscaled it. The first few hundred metres of glow in the dark, weather-indicating road will be installed in the province of Brabant in mid-2013, followed by priority induction lanes for electric vehicles, interactive lights that switch on as cars pass and wind-powered lights within the next five years.'
