Abstract

A series of studies examines the relative perceptibility of symbols for use in variable message signs on high speed roads. In each case the response latency was measured, and whilst some significant differences between symbols were found, it is concluded that response latency is not sufficiently sensitive to discriminate reliably between the perceptual features of the symbols.
