Functional Classification

Functional classification is the "process by which streets and highways are grouped into classes, or systems, according to the character of service they are intended to provide."  In basic terms, a road can be functionally classified as:

  • Arterial: These roads provide mobility so traffic can move from one place to another quickly and safely.
  • Collector: These roads link arterials and local roads and perform some duties of each.
  • Local: These roads provide access to homes, businesses, and other property.

The Alaska Department of Transportation and Public Facilities (DOT&PF) is responsible for designing, constructing, and maintaining many of these roads to ensure safe and efficient travel. To fulfill that responsibility, ADOT&PF must review and update the functional classification of all public roads, including those in your community.
