SECTION 730:15-1-4. Highway functional classification

  The state highway system shall be functionally classified under the guidelines and criteria set forth in Volume 20, Appendix 12, Highway Planning Program Manual, Highway Functional Classification, U.S. Department of Transportation, FHWA, revised March, 1989. The functional classification of the system is hereby adopted as established during the National Functional Classification of 1976 and 1993, and subsequent revisions. Classification of the system shall be Rural or Urban, based on whether the highway is inside or outside an approved Urban Area Boundary.

(1)   The Rural Functional Classification shall consist of one of the following:

(A)   Rural Principal Arterial. Rural Principal Arterials include the Interstate System and other major cross state routes. They provide an interconnecting network to major urban areas.

(B)   Rural Minor Arterial. Rural Minor Arterials include intrastate routes generally serving traffic having trip lengths and destinations traversing several counties. They provide an interconnected network between most larger cities and towns.

(C)   Rural Major Collector. Rural Major Collectors include important intracounty and some less important intercounty routes. They collect traffic from the local county road system and provide feeder service to the minor or principal arterial systems. They also provide access to most small towns and places not already interconnected with a higher class of highway.

(2)   The Urban Functional Classification shall consist of one of the following:

(A)   Urban Principal Arterial. Urban Principal Arterials include the Interstate System, Urban Freeway systems, and other major urban routes that move long distance type traffic within or through an urban area.

(B)   Urban Minor Arterial. Urban Minor Arterials are generally section line routes that serve as important travel corridors within an urban area.

(C)   Urban Collector. Urban Collectors are generally routes that disperse traffic from connecting arterials onto the local city street system within a residential or commercial development.
