Question:

Which of the following are three types of intersections?

A
Explaination

An intersection is a road junction where two or more roads cross or merge at-grade (i.e., at the same level). There are controlled, uncontrolled, and blind intersections. An interchange is a road junction where two or more roads cross over one another (i.e., at different levels) so as not to impede one another's traffic flow. There are diamond, cloverleaf, and stack interchanges, among others.
