The Study addressed the effectiveness of two reflective materials and several patterns used on lane and road closure barricades. Specific information was obtained concerning (1) detection distance; (2) pattern recognition; (3) effect of High-intensity versus Engineering grade sheetings; (4) optimum ratio of white to orange (or red) sheeting for the diamond pattern; and (5) the effect of different patterns on drivers' steering. Concerning the results of the survey: (1) Diagonal stripes do not imply directionality to most drivers, but if forced to choose in an ambiguous situation they would go the wrong way; (2) Drivers generally will go in the direction indicated by the lane closure array even if the barricade pattern is clearly contradictory; and (3) Preliminary assessment of a new Type II design indicates barricades can be made, using existing materials, that show directionality much more clearly.
