A road marker may include a housing with a cavity and at least one perimeter surface oriented perpendicular to the direction of traffic. Each of the at least two perimeter surfaces containing an opening may be substantially covered with a mesh. Further, each of the openings may form either an air input or an air output, and the air input and air output openings may be located substantially opposite to each other to generate a flow of air through the cavity. In addition, the cavity may include passive electrical components for heating the flow of air.
