Solar-powered Road Studs

Road studs (or markers) are pretty important as they help motorists find their way around at night, even more so when it is pitch black and the street lamps are all but working. Since most roads face the harsh heat of the sun all day long, how about solar-powered road markings that are smart enough to warn motorists of bad weather as well as slow-moving traffic by illuminating themselves during times of congestion in order to direct traffic from the motor way’s entry ramp to the hard shoulder? These studs are linked directly to the local traffic controller to ensure that no mix-ups occur. Well, I for one would like to see such a system being installed worldwide – after all, anything that helps reduce traffic congestion will indirectly reduce emissions from vehicles, which is always a good thing.
