Typographic Research
Finally, designers are actually doing research on readability.
In the preliminary research plan, it was assumed that the comparison typeface(s) would be from an existing sans serif typeface based on most probably a European example. Though many typefaces were reviewed — Syntax, Avenir, Thesis, Frutiger, British Transport, Normschrift, Univers, etc. — none provided an effective comparison to the standard highway fonts based on stroke, letter width, open shape of counters, and neutrality in character. We desired a simple looking typeface, but one with character and a subtle differentiation between letters to improve word recognition.
