I guess I'm not the only one to think of this. My plan was piezoelectric crystals and some sort of electro-luminescent plastic or possibly solar charged. Also for the road lines since rain makes them hard to see, age dims the paint and snow cover them up pretty bad.
The only problem is I live in a winter environment and plows scrape the hell out of the roads it would have to be embedded in the road.
