![]() Gene Hawkins, Ph.D., Paul Carlson, Ph.D., Susan T. Most notably the new bold weight mixed case showed greater legibility on freeway destination signs and a mixed case legend with the same overall footprint area out-performed an all uppercase legend.īased on the findings of the initial study by LTI, Texas DOT with the Texas A&M Transportation Institute (TTI), independently initiated research to improve guide signing for the older driver. 1997), validated our initial assumptions about design and pattern recognition. The first study of the Clearview design, conducted by LTI (Garvey, et al. (Later, the Clearview team applied lessons learned to the design and study of NPS Rawlinson Roadway, a new typeface we developed for the National Park Service.) Clearview design was informed by British Transport, a single weight typeface designed for highways in the UK in 1964 by Jock Kinneir and Margaret Calvert. Clearview (1st generation bold weight design) was compared to Series E-Modified and the newly designed Clearview Condensed (1st generation design) with mixed case was compared to Series D all upper case. Studies compared new Clearview designs to FHWA Standard Alphabets used on guide signs. What started as a general question of legibility, soon focused on the needs of the older driver. The project led to the creation of a new typeface design after, controlled field analysis revealed that existing FHWA road sign typefaces would not meet overall legibility requirements. Philip Garvey, a perceptual psychologist who had conducted older driver studies for the FHWA, subsequently joined the team. Larson Transportation Institute (LTI), Pennsylvania State University, and Donald Meeker principal, Meeker & Associates, Inc., an environmental graphic designer experienced in systems, standards and type design, initiated the Clearview project. In questioning the effectiveness of existing highway typeface legibility, Martin Pietrucha, PE, Ph.D., an engineering professor with specialty in human factors research at the T.D. A summary and full citation for each study is noted. ![]() The typeface consisted of six weights of the typefaces in both negative and positive contrast versions. The remaining four studies (Study 2, 3, 4 and 5) were based on the final version of the Clearview Typeface System design (introduced in April 2002). Although much changed in the process, the designs and the early findings provided the guidance on which Clearview development has been based. Larson Transportation Institute at Pennsylvania State University (Study 1). Of these, five studies are summarized in this section of the website. ![]() Listed below are research and design development studies prepared by various university transportation research centers, independent research consultants and designers that contributed to the development of the Clearview Type System and related application designs.
