In which of the following situations might a compound circular curve be used in roadway design?

Highway traversing relatively flat expanse
Low-speed roadway in hilly terrain
Downtown arterial roadway
All of the above

Explanation

Answer: B - A compound circular curve may be used in the design of a low-speed roadway in hilly terrain. Due to the high costs associated with constructing compound circular curved roadways, they are normally used in areas were simple curves are not cost effective. The recommended speed limits for compound circular curves are lower than those of simple and spiral curves.
