Description:

GEOMETRIC DESIGN OF ROAD ALIGNMENT HORIZONTAL The horizontal alignment is formed by a succession of straight sections (tangent) and curved sections. The curved sections can be simple or compound curves curves; which can be joined by the tangent curve transition sections (spirals). Components: - Tangent - Transition Curve - Circular Curve SECTIONS TANGENTE The minimum and maximum lengths of tangent sections depend on the guideline speed and the type of alignment between curved and tangent. Vehicles primarily remain in the curve due to the friction between the floor cross and tires; but sometimes it is not enough so inclined given to the road called superelevation
