Comparative visibility of standard luminous and nonluminous highway signs
Investigations by U S Bureau of Public Roads in cooperation with National Bureau of Standards; standardization of luminous signs; tachistoscope for regulating time of observation; averages of all observations indicate superiority of black on yellow; data on mean and extreme distances; rapidity of recognition of shape, color, and legend; night observations on daylight signs. (see also Roads and Streets v 76 n 10 Oct 1933 p 358)
