In the Netherlands light-absorbing glow-in-the-dark road markings have replaced streetlights on a 500m stretch of highway.
This looks fantastic in large part because the lane markings can actually be seen. There is something in the paint powder which is activated in daylight hours which causes the glow during nighttime. In the St. Louis area, mostly on the Missouri side, lane lines disappear at night or during rainy weather which makes me jealous of drivers in the Netherlands.
However, I'm not convinced it is a good idea to eliminate the street lights since it appears to be impossible to tell what may be in the above car level darkness. Love the way drivers can see the lanes, but it seems too one dimensional with ensuing loss of depth perception without the above ground lights.
