Texas Department of Transportation (TxDOT) sponsored research has shown that the Clearview font provides longer legibility distances than the traditional highway gothic font Series E (Modified) when used on freeway guide signs. Additional studies have shown that Clearview outperforms other versions of highway gothic fonts on other smaller types of guide signs. These results, which were all carried out using positive contrast signs, have helped support the adoption of the Clearview font into FHWAs Standard Highway Signs book. The approval of the Clearview font in the Standard Highway Signs book has allowed a new version of Clearview to be used on negative contrast signs. These signs include those with white, yellow, orange, and yellow-green backgrounds. At present, TxDOT plans to continue using the standard highway gothic font for negative contrast signs. However, if research were to find a benefit to using Clearview for negative contrast signs, TxDOT could implement Clearview for all signs used by the department, simplifying sign fabrication processes. This research is focused on the viability of adopting Clearview for negative contrast signs based on visibility performance measures. The research also addresses potential changes in sign design/layout that may be needed to implement Clearview.
