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.
SPECIAL NOTE: The VDOT Commissioner has identified
specific federally functionally classified minor arterial highways that will be
subject to the VDOT Access Management regulations and standards for principal
arterial routes under the authority granted in VA Code §33.1-198.1. These routes
were identified based on their regional significance and value for emergency
evacuation purposes. For more
information on the
Access Management regulations and standards, please refer to the information
and maps available on VDOT’s access management Web pages.
