ABSTRACT:
This disclosure is concerned with distinctively and unambiguously marking the directions of travel on motoring highways, airports and other surfaces with the aid of a thin novel saw-tooth marker strip that is adhered to the traveling surface and has distinctively colored successive surfaces of retroreflecting materials, sometimes oriented almost vertically or with a substantial vertical component, operable to alert the motorist or other traveler of the direction of travel approaching such surfaces, and intermediate surfaces therebetween of different color, sometimes optically diffuse and sometimes retroreflective, to indicate the opposite direction of travel.
