Federal-Aid Highways and State Highway System Update System Identification and Functional Classification

The Hawaii State Department of Transportation has updated the federal aid urban boundaries (FAUB) and functional classifications of the Federal-Aid and State Highway Systems to incorporate changes from the 2010 US Census, economic growth, and travel needs.

The FAUB indentifies places with populations of over 5000 as well as areas where there is an urban use. The FAUB is used mainly for funding and design purposes for highway projects. The FAUB also affects the Highway Performance Monitoring System and federal-aid roadway functional classification.

The FAUB is not to be confused with urban boundaries defined by US Census.

The following reports were approved by the Federal Highway Administration on April 8, 2013 and completed in cooperation with the Oahu Metropolitan Planning Organization (OahuMPO), City and County of Honolulu Department of Transportation Services (DTS) and Department of Planning and Permitting (DPP), County of Hawaii, County of Maui and County of Kauai.
