BARRICADE STUDY

IT HAS BEEN SUGGESTED THAT VEHICLES STRIKE BARRICADES BECAUSE THE DRIVERS MISJUDGE THE LATERAL CLEARANCE BETWEEN THE BARRICADES AND THEIR VEHICLES AND THAT A WELL DEFINED VERTICAL EDGE PLACED UPON THE TRAFFIC SIDE OF BARRICADES WOULD REMEDY THIS PROBLEM. THE PURPOSE WAS TO TEST THE EFFECTIVENESS OF THESE VERTICAL EDGES, INTENDED TO SERVE AS CLEARANCE AIDS. IT WAS CONCLUDED THAT THEY WERE INEFFECTIVE IN HELPING DRIVER JUDGE LATERAL CLEARANCE. THE CLEARANCE AIDS WERE ORANGE STRIPS WITHOUT REFLECTIVE PROPERTIES. /HSL/
