Federal Functional Classification vs. State Functional Classification
Federal functional classification guidelines are used in functionally classifying Virginia roadways.
However, Virginia currently also uses other classifications.
State administrative-funding classifications are used to refer to the state primary, secondary and urban systems.
The state functional classification parallels the federal system, except the state system does not include non-existing roadways.
The percentage thresholds used by the Federal Highway Administration are slightly modified and federal major collectors are classified as minor arterials in the state system.
Virginia has applications that use the federal system in mixture with the state administrative systems.
One example is distributing maintenance funds for urban and urbanized area localities that undertake maintenance responsibility in their jurisdiction.
