Application of gestalt psychology in highway design process

Gestalt Psychology is one of those theories which may be useful in engineering design process, especially in road designing. This theory explains the process of organisation and recognition of objects in the space observed by the driver. The universal Gestalt laws may explain some unsolved problems of road visualisation and perception from psychological side. The main Gestalt laws suggest, that perceptual interrelations in the visual field are in some way regular, which may aid the process of designing safe and aesthetic solutions in the dynamic space of road system. This research considers only those Gestalt laws, which may be applicable to traffic engineering, to explain the perceptual process of the road environment.
