Abstract
Pavement marking is a kind of traffic safety facility that plays important role in road safety. As the development and application of ergonomics in traffic engineering and road safety, perceptual markings appeared in Japan, America and Europe. Perceptual markings warn drivers of potential danger or inform drivers of road condition change by special figure, color, alignment, textile or their combinations that can offer drivers visual, tactile or aural sensations. This paper gives an overall introduction of perceptual markings and their typical application and practice, which can be referred by traffic practitioners. (Author/publisher)
