In this study, Clearview performed no worse than, and in some cases outperformed, Series E-modified. The researchers evaluated shoulder and overhead mounted highway guide signs on Type III retroreflective sheeting. The testing of Clearview by TTI compared the revised typeface to Series E-modified.

The first upgrade to Clearview involved refinement of the font prior to the testing at TTI. Pilot testing at TTI indicated that there were significant differences in the legibility of full-scale signs as compared to the smaller signs tested at PTI, when viewed at design legibility distances (40 feet per inch). The first Texas Transportation Institute (TTI) research study compared full-scale freeway guide signs using Clearview-Bold and E-modified alphabets.
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.

The research revealed that when the upper/lowercase Clearview-Condensed (condensed) is compared to the most commonly used all-capital-letter typeface (FHWA Series D), there was a 14 percent increase in recognition when viewed by older drivers at night, with no loss of legibility.

With Clearview-Bold, the desired destination legend is recognized 1.3 seconds earlier (84 feet) and with greater accuracy, giving the driver significantly more time to react to the information displayed.īy 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. On a road with a posted speed of 45 mph, a driver is traveling at 66 feet per second. For drivers traveling at 45 mph, that legibility enhancement could easily translate into 80 extra feet of reading distance, or a substantial 1.2 seconds of additional reading time. In two PTI studies intended for conventional road guide signs, use of an early version of the Clearview Bold improved nighttime sign reading distance by up to 16 percent when compared with the E-modified road sign typeface. The initial research on Clearview was conducted at the Pennsylvania Transportation Institute.
