What if roads were also solar panels ? The power they collect could be used to power LED lane markers, road signs and warnoing signs. And possibly heating elements to melt snow and ice. And even better put power into the GRID. "... road ... [that] housed solar cells to collect energy, which could pay for the cost of the panel, thereby creating a road that would pay for itself over time. ... ideas and possibilities just continued to roll in and the Solar Roadway project was born."
