SNOWPLOWABLE RAISED REFLECTIVE PAVEMENT MARKERS AT HAZARDOUS LOCATIONS IN NEW JERSEY

Snowplowable raised reflective pavement markers were installed at three hazardous sites in New Jersey--a winding two lane rural road, a two lane downhill approach to a circle, and one direction of a three lane curve. The major evaluative findings after one year of use are that: (1) total accidents were an average of 29 per year before and 31 during the first year after installation, (2) after one year of use the markers could be seen as far as 1,400 feet from a car with low beams on a dark road, (3) during the first year up to 9.5 percent of reflectors needed to be replaced, but no castings were damaged, (4) spacings should vary according to degree of road curvature, (5) the estimated installation costs at these sites varied from $20 to $26 per marker, and (6) the installation equipment design should be improved. Detailed methods and findings with comments can be found in the report.
