Geometric design

Geometric roadway design encompasses the strategic arrangement of physical elements on roads to optimize efficiency, safety, and environmental impact. It includes three key components: alignment, profile, and cross-section, which together establish a comprehensive three-dimensional layout for the roadway. By considering factors such as horizontal tangents, curves, vertical aspects, and cross slopes, geometric design plays a vital role in creating roads that foster livability and cater to diverse travel modes and community needs.
