Design of Horizontal and vertical alignment of Expressway for the speed of 150kmph – ‘A Review’
The design of roads is an important aspect in the development of road infrastructures which significantly impacts the economy, environment and society of the region. The design of road alignments, which defines how the road will traverse the terrain and geography, is particularly interesting as there can be virtually infinite number of alternatives on how the road alignment is planned based on design speed. There is a need to carefully design the alignment for that road alignment to be most economical, environmentally friendly, comply with society and promote good transportation. The Objective of this journal is to propose a method that the project highway will be designed for the speed of 150kmph and it should be economical, geometrically satisfied and feasible. While designing the horizontal alignment several factors shall be taken e.g., sight distance for good visibility, desirable radius, adequate transition curve etc. and at the time of vertical alignment design, it is to be take care that there should not be higher cutting or filling to minimize the earthwork. It makes the project economical.
