Two experimental versions of the x-shaped railway crossbuck sign (white with red border, and yellow with black border) and the Canadian standard were compared in a series of four experiments. The angular separation between the blades of the sign was varied (45 deg and 90 deg), and all signs were tested against both a grass-green and a sky-blue background. Standard Canadian regulatory and warning signs were used as distractor stimuli in all experiments. Laboratory measures of classification time, glance legibility, and legibility distance indicated the experimental versions to be generally superior to the existing standard. Legibility distance was greater for signs with blades separated by 90 deg than for those with 45 deg angles. A final experiment revealed initial comprehension of the red and white crossbuck to be better than that for the yellow and black version.(a)
