Abstract: A traffic safety aid consists of a prefabricated essentially flexible marking tape material which is adapted to be laid on and adhesively secured to a roadway surface, at predetermined locations which are to be detected and identified at a distance by a driver of a vehicle. The tape material has an upper face, a plurality of protrusions spaced lengthwise of the upper face. Each protrusion has the capability of emitting visible light when energy is applied thereto. Each protruse may contain a luminescent substance adapted to emit visible energy when excited by invisible or not visible radiations, or electric sources adapted to emit visible light when electric energy is applied through insulated leads pre-arranged in the tape material.
