Importance of Geometric Design in Highway

-Geometric design of highways deals with the layout and dimensions of visible features of the highway such as horizontal and vertical alignments, sight distance, intersections etc. The geometrics of highway has to be designed to generate sufficiency in traffic operations with maximum safety at reasonable cost.

It is very much possible to design and construct the pavement of a road in successive different stages; but it is very costly and rather hard to improve the geometric elements of a road in stages at a later time.

Geometric design of highways deals with the following elements:

-Cross section elements.

-Sight distance considerations.

-Horizontal alignment details.

-Vertical alignment details.

-Intersection elements.
