Determining road types in the Mid Atlantic region aligns with the Waze USA Standard for freeway, major highway, minor highways, and primary streets. The Waze USA standard is a hybrid system based on a national standard called "functional classification" with a few modifications.
Functional classification maps are available for most states. Compliance across state borders is important to insure better route selections between states; however, editors in some states have deferred adoption of the USA Standard due to in-state concerns.

Road Segment Naming
