Abstract

In 1992, the U.S. Federal Highway Administration (FHA) initiated a pilot study in conjunction with the National Park Service that examined the effects of new color signs on motorist behavior at 5 pedestrian and bicycle crossings in the Washington, D.C., area. A similar but more expansive FHA study, in 1993, was conducted nationwide. After review and analysis of these studies and the accompanying data, it was concluded that fluorescent yellow-green warning signs improved the conspicuity of the sign message, and motorists were able to recognize the sign from greater distances than the standard yellow warning sign.
