ABSTRACT:
A plurality of uni-directional light reflective lane markers are adapted for securance on a roadway to separate and delineate laterally adjacent traffic lanes from each other. Each lane marker comprises an elongated delineating strip extending longitudinally in a first direction and a plurality of longitudinally spaced light reflectors on the delineating strip for visually displaying the strip when it is viewed in the first direction and for at least substantially rendering the strip invisible when it is viewed in the second direction, opposite to the first direction. Thus, a particular traffic lane is clearly delineated for traffic travelling in the first direction, but is rendered substantially invisible when viewed by traffic travelling in the second, opposite directions. Conversely, the lanes for traffic travelling in the second direction are clearly delineated for oppositely moving traffic. Each lane marker preferably comprises a molded plastic member embedded in flush relationship in the roadway and the light reflectors are defined on exposed leading surfaces, formed on the proximal sides of a plurality of longitudinally spaced segments formed within the member.
