David Dunlap goes deep on the new mixed-case street signs that you see going up all over the city:
“Clearview’s [the typeface on the new sign] primary mission is to improve on the legibility of the standard alphabet used for traffic signs, known officially as the FHWA series but colloquially as Highway Gothic. …In discussing its policy, the highway agency said there were demonstrable gains in legibility when mixed-case Clearview letters appeared on a reflective surface called microprismatic sheeting.”
Safety, schmafety, I still say the mixed-case signs are ugly.
