DISCUSSION OF HIGHWAY ALTGNMENT DESIGN IN DEVELOPING AREAS

This article discusses the highway alignment design in the developing areas. Thecinclusion reached is as follows:During the first alignment design,the desinger should notonly satisfy the alignment target of classiefied highway,but also consides the targets of intersection angle and the straight line length addation between horizontal curves. Once theabove mentioned targets being satisfied, the investment and the land source needed can bereduced greatly when the alignment classification is raised
