Geometric design of roads

The Autovía del Olivar which unites Úbeda with Estepa in Andalucia in southern Spain. A geometric design saved on construction costs and improved visibility with the intention to reduce the likelihood of traffic incidents

The geometric design of roads is the branch of highway engineering concerned with the positioning of the physical elements of the roadway according to standards and constraints. The basic objectives in geometric design are to optimize efficiency and safety while minimizing cost and environmental damage. Geometric design also affects an emerging fifth objective called "livability," which is defined as designing roads to foster broader community goals, including providing access to employment, schools, businesses and residences, accommodate a range of travel modes such as walking, bicycling, transit, and automobiles, and minimizing fuel use, emissions and environmental damage.
