Compound and Reversed Curves
Compound Curves A compound curve consists of two (or more) circular curves between curves between two main tangents joined at point of compound curve (PCC). Curve at PC is designated as 1 (R 1, L1, 1, etc) and curve at !ig!er station is designated as " (R ", L", ", etc).

Reversed Curve
Reversed curve, t!oug! pleasing to t!e e$e, would bring discomfort to motorist running at design speed. !e instant c!ange in direction at t!e PRC broug!t some safet$ problems. 0espite t!is fact, reversed curves are being used wit! great success on par roads, formal pat!s, waterwa$ c!annels, and t!e lie.
