Standards of Geometric Design of Highway: A Review

Geometric design of highway deals with designing of physical visible features of highway those comprise of cross-sectional elements, sight distances, alignment, curves, superelevation, and other allied features. India is one of the country having population increases progressively causes traffic volume more. In addition to that sanctioning of funds from government for transportation infrastructure development is not satisfactory. So that it is preferable to plan and design the geometric elements of the road during the initial alignment stage it by considering future traffic growth. And it is very difficult to improve geometric elements after construction and cause to unwanted capital investment. This paper presents review on past work done on geometric design of highway and emphasize planning and designing of geometric features. Although there are number of factors influences on design of highway, but suitable geometric design having objective of giving optimum efficiency in traffic operation with contentment safety measures at reasonable cost.
