Abstract

The function of traffic signs is becoming increasingly critical as more and more automobiles take to the road and more and more multi-lane expressways are built. The speed and volume of traffic, and the complex interchanges on our thruways and expressways require signs that must be recognized and understood at a glance, day and night. This article describes briefly the general post-war development of acrylic signs and their characteristics, and in more detail the factors of legibility, lighting, color and location as applied to internally lighted traffic signs.
