What characterizes an expressway?

An expressway is characterized as a divided highway that features controlled access. This means that entry and exit points to the expressway are limited to certain designated interchanges or ramps rather than allowing unrestricted access from surrounding roads or properties. The controlled access helps facilitate the flow of high-speed traffic by minimizing the number of points where vehicles can enter or exit, thus reducing traffic conflicts, improving safety, and enhancing traffic efficiency.

This design is distinct from options that refer to highways with no access control, local traffic roads, or one-way streets in urban settings, all of which do not maintain the same operational characteristics or traffic flow standards as expressways. The unique design of an expressway supports faster travel times over long distances, making it integral to regional transportation networks.
