Title: Research Pays Off: Improving Guide Sign Legibility: New Lettering Reads Larger, Clearer, Farther
Accession Number: 01024771
Record Type: Component
Availability: Find a library where document is available Abstract: The traditional lettering design on highway guide signs, which is usually fully retroreflective, was found in a 1994 study by the Federal Highway Administration to be inadequate for older drivers. Research by the Texas Transportation Institute, building on research findings of the Pennsylvania Transportation Institute, determined that the Clearview font on guide signs, combined with retroreflective sheeting for white Clearview text on a green background, using the most efficient microprismatic materials for the legend with high-intensity materials for the background, yielded a win-win situation. The signing agency gains durability and cost-efficiency in the signs, and drivers gain contrast, which is beneficial for legibility in dark conditions.
