DEVELOPMENT AND EVALUATION OF RAISED TRAFFIC LANE MARKERS 1953 TO 1968: FINAL REPORT

THE STATE OF CALIFORNIA HAS EVALUATED AND ADOPTED A SYSTEM FOR DELINEATING TRAFFIC LANES USING RAISED PAVEMENT MARKERS FOR MOST AREAS OF THE STATE. FOUR WHITE NON-REFLECTIVE MARKERS ARE PLACED ON THREE FOOT CENTERS FOLLOWED BY A FIFTEEN FOOT GAP. A REFLECTIVE MARKER IS PLACED IN THE CENTER OF EACH GAP ON CURVES AND IN THE CENTER OF EVERY OTHER GAP ON TANGENTS. RAISED YELLOW MARKERS ARE USED AT THE LEFT EDGE OF THE LANE NEAR THE MEDIAN OF DIVIDED HIGHWAYS. THIS SYSTEM IS MUCH MORE DURABLE THAN TRAFFIC PAINT, GIVES EXCELLENT NIGHTTIME VISIBILITY IN GOOD WEATHER, AND PROVIDES GOOD NIGHTTIME VISIBILITY IN ALL BUT HEAVY FOG.
