Decision-Making Method of Grey Lattice Order for the Through Scheme of Arterial Highways in a City Area

Abstract

For scientific and reasonable decision making regarding the through scheme of arterial highways in city areas, the grey correlation is commonly used to measure the closeness between an alternative scheme and an ideal scheme. In this paper, a grey lattice order decision-making method is proposed, and using the proposed method, the through schemes of arterial highway G204 in Yancheng City are compared. The analysis indicates that from the aspects of economic and environmental impacts, the through model that bypasses the city is the best through scheme despite an increase in detour distance of the vehicles using the route. The application results show that the grey lattice order method combines the advantages of the grey correlation and lattice order methods to better reflect the relative relationships of the pros and cons between alternatives.
