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.

A roadway defining at least one pair of side-by-side first and second traffic lanes for conveying traffic in first and second opposite directions, respectively, and a unidirectional light reflective lane marker secured on said roadway comprising at least one delineating strip separating said traffic

A roadway defining at least one pair of side-by-side first and second traffic lanes for conveying traffic in first and second opposite directions, respectively, and a unidirectional light reflective lane marker secured on said roadway comprising at least one delineating strip separating said traffic lanes from each other, said delineating strip comprising light reflective means for visually displaying said delineating strip when it is subjected to light and viewed by a driver travelling in said first direction on said first traffic lane and for at least substantially rendering said delineating strip invisible when it is viewed by a driver travelling in said second direction on said second traffic lane, means defining an elongated groove in an upper surface of said roadway and wherein said lane marker, including said light reflective means, is secured and entirely confined within said groove, said delineating strip comprising an elongated, opaque and one-piece member defining a flat upper surface disposed in a horizontal plane flush with an upper surface of said roadway, and an elongated slot formed in the upper surface of said member and solely interrupted by a series of longitudinally spaced segments formed integrally within said member and bridged laterally across said slot, each said segment comprising a leading surface on a proximal side of said segment, a trailing surface on a distal side of said segment and a flat intermediate surface flush with the flat upper surface of said member and with the upper surface of said roadway, said light reflective means being disposed and confined solely on the leading surface of said segment and in fully protected relationship within said groove.
