WebCurved roadway sections on higher speed roads are gener- ally constructed with superelevation to compensate for the centripetal forces exerted on the vehicles, making it easier for the driver to control the vehicle through the curved section. Guidelines for the design of CSRS are found in the Green Book. WebStep 1: Calculate the superelevation necessary for 75% design speed and assume No lateral friction is developed If e value is less than e max = 0.07, provide calculated e value. …

Superelevation works with several interacting forces of physics to help drivers maintain speed and stay safely on the road through a curve. A complex combination of centrifugal and centripetal force, friction, inertia, weight, and velocity or speed all interplay to determine the need for superelevation on a road or … See more Superelevation is a method of infrastructure constructionused in roadway curves where the outer edge of the pavement is raised above the inner edge.
