Road signal systems and methods for controlling road signals include a piezoelectric layer integrated with a surface that undergoes stresses with traffic passing over the surface. A power collection circuit is configured to collect and store power from the piezoelectric layer. One or more devices receive electrical power from the power collection circuit responsive to traffic passing over the surface.
