Clearview font has been well received by our customers, who appreciate Clearview’s legibility, aesthetics, and lack of nighttime halation (over glow). “VDOT’s experience with Clearview font has been very positive there have been no documented legibility or driver confusion issues resulting from VDOT’s widespread Clearview conversion. Kilpatrick, P.E., Commissioner of Highways, Virginia Department of Transportation, responding to the FHWA request for public comment, wrote: In 2014 the FHWA recommended use of Clearview in their: Handbook for Designing Roadways for the Aging Population.Ĭharles A. ![]() The next fourteen years, state DOTs installed tens of thousands of signs that could be read more easily from a greater distance thereby giving drivers more precious reaction time. Of those 18, all recognized the improvement from the first viewing of l installations. Thirty states applied to FHWA for use eighteen of those would commit to statewide implementation programs to upgrade guide signs. FHWA gave Interim Approval for guide signs (positive contrast applications) in 2004. The Pennsylvania Department of Transportation made application to FHWA for approval to use Clearview on freeways and conventional road guide signs. The FHWA recognized the importance of the final Clearview design as reviewed in 2002 on the LTI test track at the Pennsylvania State University. (ret.), Chief, Traffic Engineering & Operations for PennDOT (2002) said: “The design and development of Clearview was the most important advancement in road signing in 30 years.” The Pennsylvania Department of Transportation was the first state to prototype Clearview on state highways. Texas Department of Transportation and the Texas A&M Transportation Institute sponsored five studies on performance of Clearview compared to FHWA and UK standards. The 3M Company provided a significant research grant to design two typefaces and study their effectiveness for older drivers, day and night and cast 3M research scientists in an advisory role. TD Larson Transportation Institute (LTI) took on the first study and partnered in this project. On the other hand, our training in type design, systems design and human factors engineering guided us to try to understand why the standard is inadequate and how things could improve. We had no idea that it would gain more than academic attention, or that our work could save lives. We started the Clearview project with a goal of enhancing readability of traffic signs. In a world where design is integral to communication systems, traffic control devices remained an untouchable outlier as comments about road sign clutter and inconsistency brought on a roll of the eyes and the comment, “It is what it is.”
