GEOMETRIC DESIGN OF HIGHWAY

ABSTRACT

Geometric design of highways is an important factor to be considered before highway construction as it necessitates the determination of specific design elements, which include: the number of lanes, lane width, median and width, length of acceleration and deceleration lanes for on and off ramps, need for truck climbing lanes for steep grades, curve radii required for vehicle turning and the alignment required to provide adequate stopping and passing sight distances.  This project work focuses mainly on highway horizontal and vertical alignments which are the most important components of geometric design and intersection. These project works also discusses geometric design of cross section,, sight distance, procedures for highway alignment and the comprehensive plan and profile detailing using manual and automated then comparing the result.
