Functional Classification System of Streets

Transportation Planning Organization

Functional classification is the process by which streets and highways are grouped into classes, or systems, according to the character of traffic service that they are intended to provide. There are three highway functional classifications: arterial, collector, and local roads. All streets and highways are grouped into one of these classes, depending on the character of the traffic (i.e., local or long distance) and the degree of land access that they allow.  (Flexibility in Highway Design, U.S. Department of Transportation, Federal Highway Administration).
