Road profiles and curves

Geometric design of the road horizontal alignment the horizontal alignment is formed by the succession of straight sections (tangents) and curved sections. curved sections can be simple curves or compound curves; which can be joined to the tangent sections by means of transition curves (clothoids). Components: - Tangent - Transition curve - Circular curve Tangent sections The minimum and maximum lengths of the tangent sections will depend on the design speed and the type of alignment between curved and tangent. vehicles stay in the curve primarily due to transverse friction between the pavement and their tires; but sometimes it is not enough, so an inclination is given to the road called cant
