WebFor crest curves the only criterion that applies is sight distance. 2.2) Horizontal curves Horizontal curves are usually segments of circles, which have radii that will provide a smooth flow of traffic along the curve5. There are three basic types of horizontal curves: simple, compound, and reverse (transition) curves. WebIf reversing curves must be used, the reversing superelevation is accomplished by setting the level section (0.0%) at the P.R.C. and transition to and from this section using appropriate "C" factor. 11. • Avoid the use of "broken-back" curves. The use of compound curves is preferred over short tangents between curves in the same direction. 170 share trading technical analysis
