Question

Quizplus · Accepted Answer

The rate of superelevation that can be attained in an urban setting is limited by the presence of driveways, the right-of-way allowances, and intersection spacing. Because of these limitations, superelevation rates are generally low in urban settings (maximum 4% and 6%). On the other hand, in rural settings where ice and snow are uncommon, superelevation rates of up to 10% and 12% may be used when setting a roadway alignment.
