摘要

The study investigated the durability of sign face materials through field surveys, the effect of weather conditions (dew, mists, fog, smoke, and rain) on sign performance, the effect of sign angular position on preventing the specular mirror problem, the effect of sign lateral position, the effect of material combinations on legibility and detection distances as measured by small sign elements and through a survey of large guide signs in three Florida cities. A part of the investigation set the level of specific intensity per unit of area marking the end of service life for reflective sheeting and acrylic button reflectors and the level of appearance for nonreflective porcelain enamel backgrounds. Recommendations are made for an updated specification for reflective sheeting, a design policy using certain material combinations for different weather and roadway situations, improved control over screened colors, use of Type II A sheeting, angular mounting of signs, etc.
