What type of intersections are turnabouts and railroad crossings considered?

Turnabouts and railroad crossings are considered non-traditional intersections because they do not conform to the standard layout or function of typical intersections found in urban and suburban areas. Traditional intersections usually involve the crossing of two or more roads where traffic signals or stop signs regulate the flow of traffic.

In contrast, turnabouts serve as a method for vehicles to reverse direction in a more compact and space-efficient manner, which is different from the typical traffic signal-regulated intersection. Railroad crossings, on the other hand, have specific safety protocols and signals distinct from traditional intersections, designed specifically to manage the interaction between vehicle traffic and trains. These characteristics set them apart, thus classifying them as non-traditional intersections.
