(DRAFT) National Functional Classification (NFC) Road Types

A state-wide effort to align road types to MDOT's National Functional Classification (NFC) maps began in late 2013. Rather than relying upon the appearance of the road, NFC considers the overall function of the road as determined by MDOT. While attributes such as number of lanes, speed limits, and number of access points are important aspects of the appearance of a road; they may have less impact on classification than functional considerations such as annual average daily traffic. numerous local roads

While there are exceptions that are listed below, the following table provides the NFC classifications with their corresponding Waze road types as adopted in Michigan.

NFC Type Waze Road Type Comments
Interstate Freeway
Other Freeway Freeway
Other Principal Arterial Major Highway
Minor Arterial Minor Highway
Major Collector Primary Street
Minor Collector Primary Street
Local Street

Prior to reclassifying any road segment to its NFC type, the following levels of precedence should be observed:

  1. Private roads should be classified as "Private Road" (even if a dirt road)
  2. Non-private dirt roads should be classified as "Dirt road / 4X4 Trail"
  3. Any road classified higher than the current NFC type due to a separate state-wide standard or local editor judgment should remain as is. The rule as discussed in the Michigan forum is never to downgrade a road type, only upgrade to its NFC type. For example, a county highway with the Michigan A-F designation that may be a major collector in NFC would be classified as a "Minor Highway" due to other accepted guidelines.
  4. If all of the above conditions are met, the road segment can be edited to match the corresponding NFC type.
