Geometric design

Geometric design involves creating the layout and physical features of transportation routes, such as roads, railways, and airports. It focuses on shaping the alignment, profile, and cross-section to ensure safety, efficiency, and comfort for users. This includes decisions about where the route goes, how sharp turns are, the slope of the road, and lane widths. Good geometric design minimizes accidents, reduces travel time, and provides smooth navigation. It combines engineering principles with the terrain and traffic needs to develop functional and safe transportation infrastructure.
