I’ve been noticing that the signs on the major roadways have been slowly integrating a new typeface. I have to say I am a big fan. After doing a quick iPhone search, I found out that the new typeface is called, “Clearview” by James Montalbane. Apparently in 2004, the U.S. Federal Government passed a law allowing states to adopt the new typeface. It appears that it’s for a good reason too.
According to Clearviewhwy.com, “Pennsylvania Transportation Institute In two PTI studies intended for conventional road guide signs (Figure 1), use of an early version of the Clearview-Bold (left position, original version of typeface) improved nighttime sign reading distance by up to 16 percent when compared with the E-modified road sign typeface (right position).”
“By allowing a viewer to read the unique footprint of the word when displayed in upper/lowercase letters, there is an increase in accuracy, viewing distance, and reaction time. The research (Figure 2) revealed that when the upper/lowercase Clearview-Condensed (upper position, original version of typeface) is compared to the most commonly used all-capital-letter typeface (FHWA Series D, lower position), there was a 14 percent increase in recognition when viewed by older drivers at night, with no loss of legibility. When the size of Clearview-Condensed was increased by 12 percent to equal the overall footprint of the uppercase display, the recognition gain doubled to 29 percent with little change in overall sign size.”
