Clearer Road Signs Ahead

To address issues of legibility and visibility of road signs from a distance and at night, a new font, named Clearview, was developed by Meeker & Associates and tested by the Pennsylvania Transportation Institute (PTI) at Pennsylvania State University. After creating initial versions of the fonts, the authors subjected them to an iterative design process based on the results of subjective field evaluations, objective tests of the typefaces' degradability, and objective laboratory studies using computer simulation. The steps in this evaluation process are described here.
