EVALUATION OF REFLECTORIZED SIGN SHEETING FOR NONILLUMINATED FREEWAY OVERHEAD GUIDE SIGNS

A comparative evaluation of various combinations of reflective sheeting (Level 1 = high-intensity, super-engineering grade; and Level 2 = engineering grade) on nonilluminated freeway overhead guide signs was made under road test conditions. A panel of nontechnical observers was used in a subjective evaluation of the signs. Luminance measurements were made by using a telephotometer at the front passenger's eye position using low-beam headlights together with traffic stream headlight illumination. Cost analyses were also performed. The study concluded that, pending the results of further tests on high-intensity versus super-engineering grade for sign message and border, the recommended course of action for freeway overhead guide signs was to implement high-intensity foreground (legend and border) on engineering-grade background.
