Highway Roadside and Median Green Belts Design Method Based on the Theory of Dynamic Vision

Abstract

Unity and change are the basic principles of highway landscape design. Based on the investigation of highway revegetation, new concept of revegetation design was given. Bad roadside landscape should be sheltered by green belts, and beautiful roadside landscape should be divulged or showed by locally eliminating the green belts, and maximum length of green belts with single pattern should be limited for preventing drivers from dozing. Based on the theory of dynamic vision, this paper presents the formulas for computing the stake numbers of setting or eliminating the green belts according to the requirements of landscape design, and the formulas for computing the maximum length of green belts with single pattern. The results are helpful to the highway roadside and median green belts design.
