Abstract:

Unlighted highway signs using newly developed retroreflective materials were installed along the Gowanus Expressway. Photometric measurements of the signs were used to assess the visibility of the signs using the relative visual performance model. The calculated visibility of the unlighted signs was similar to that of a lighted sign conforming to present recommendations for exterior sign lighting. The results of a series of subjective observations of sign contrast suggest that individuals can see differences in sign appearance that could have little or no impact on visual performance.
