Better, More Readable Signage

This article discusses the various components that go into making road signs more readable. A standard sign alphabet was first adopted about 1950 after studies by the Canadian Department of Transportation. About 40 years ago, the Federal Highway Administration took the next big step by adopting the recommendation of using upper and lower case letters placed on quarter-inch grids. Six tables provided width and spacing. In 1977, a metric version was created. New alphabets were required when sign-making moved to electronic methods, and the new standard alphabets work for both English and metric measures of spacing. Fonts, families of letters and sign material are also discussed.
