PURPOSE: A road surface heating apparatus is provided to prevent sliding due to rain fall and icing on a road using electricity stored through the piezoelectric element. CONSTITUTION: A road surface heating apparatus(100) comprises a controller(110), a piezoelectric element(120), a condenser(130), a sensor(140), and a heater(150). The piezoelectric element is embedded on the road and generates electric charge using the weight of the vehicle as physical power. The condenser stores electric charge generated by the piezoelectric element. The sensor senses snowfall, rain fall, and icing on the road. The heater is installed on the road and generates heat using the electric charge stored in the condenser. The controller controls the operation of the heater according to the signals. |
