This document serves as a comprehensive technical manual for geometric road design, detailing the essential parameters required to create safe and efficient transport infrastructure. It outlines critical design controls, such as operating speeds, vehicle classifications, and the specific needs of vulnerable road users like cyclists and pedestrians. Extensive guidance is provided on horizontal and vertical alignments, including the mathematical application of circular curves, superelevation, and sight distances. The text also defines standard cross-section components, covering everything from traffic lanes and shoulders to  ...
