Pennsylvania was the first state to implement this new Clearview font on highways like Routes 322 and 80.

In particular, older drivers had issues reading Highway Gothic signs at night due to a glowing halo effect around the white letters.Įnter Penn State and the PTI.

Researches at the Pennsylvania Transportation Institute (PTI), a unit of Penn State’s College of Engineering, helped develop and test the typeface Clearview in the late 1990s and early 2000s, which eventually appeared on highway signs all around the country.įor background, the Federal Highway Administration (FHWA) found issues with Highway Gothic, the typeface used on highway signs since 1948, and was looking for a more modern font. In fact, they were thinking really long and really hard about these fonts. It turns out some folks at Penn State actually were thinking about highway sign typefaces. Critically, an ineffective design remains so at any size.īeginning in 1991, the Clearview design and research team focused on the needs of the older driver.Although you’ve driven past thousands of highway signs in your life, you probably never stopped to think about the big, white typeface on them. Enlarging signs to improve readability was a proposed solution limited by space and the engineering challenge of mounting big signs. Studies by FHWA confirmed the need but the solutions utilizing standard FHWA typefaces fell short.

Since the mid 1980s, the FHWA was aware that the older driver population, a growing percentage of the driving population, would require accommodation.

Without scientific evaluation of readability and overall performance of the fonts, the new multi-weight series of typefaces was added to the MUTCD, the federal regulation for conventional road sign legends The fonts were intended for positive contrast applications only. These new fonts adopted the chamfered ascenders and descenders and constrained interior shapes of E-Modified. In 2003 the FHWA added a series of lower-case letters to each of the five all upper-case fonts for use on street name and conventional road guide signs. Though much questioned and criticized by optics engineers, retroreflective sheeting manufacturers and human factors scientists working to improve road safety for older drivers, Series E-Modified, arguably the “Rube Goldberg” font, remained the standard for over five decades. The Series E-Modified typeface for new signs was adopted from the 1948 typeface Ted Forbes developed for the divided highways in California. With that, a new type of guide sign designed for high speed limited access roads displayed destination names in advance of exits, bifurcations or continuing directions. Eisenhower signed the Federal Aid Highway Act establishing the Interstate Federal Highway System. The weighty typeface has tiny interior shapes that is lost by overglow of letter stroke when used with modern high brightness materials chamfered ascending letters and descending letters were added at a time and for reasons unknown. Based on the mechanical quality of this typeface, it is assumed that Forbes used some type of lettering template and ruling pen to shape the initial lettering style that was then manipulated to accommodate retroreflective buttons. Series E-Modified, a mixed case typeface, has its roots in, the 1948 typeface developed by Ted Forbes, a highway engineer with Caltrans. While technological advancements were applied to sign production processes, lettering style saw little change.

The lettering weight used was determined by how it fit on a particular sign panel. The condensed version had a thinner stroke.

The design assumed that the wider the letter and thicker stroke width was easier to read from long distances. The fonts were standardized in six different weights of block lettering from a wide sized lettering to a very condensed version of the series. The fonts originated from hand-painted brush lettering on guide signs, or hand-cut masks for screen printing regulatory signs in multiples. Highway officials adopted upper case in block letters for guide and regulatory signs. In 1927 the American Association of State Highway Officials (now AASHTO) published their first highway manual.
