Highway Functional Classification: Concepts, Criteria and Procedures

Our nation’s roadway system is a vast network that connects places and people within and across national borders. Planners and engineers have developed elements of this network with particular travel objectives in mind. These objectives range from serving long-distance passenger and freight needs to serving neighborhood travel from residential developments to nearby shopping centers. The functional classification of roadways defines the role each element of the roadway network plays in serving these travel needs. Ultimately, the coordinated and systematic maintenance of an accurate roadway functional classification system ensures that Federal Aid funds are allocated where they are most needed, to enable people and goods move fluidly through our modern transportation system.

The Highway Functional Classification: Concepts, Criteria and Procedures, 2013 Edition, describes the procedures and processes for assigning functional classifications to roadways and adjusting urban area boundaries. This document builds upon and modifies prior guidance documents.
