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

Often when US Hwys, State Roads, and County Roads pass through municipalities, they have a local name (e.g, "Main St"). Please see Road names for instructions on how to name these segments. Check here for other states.


The Mid Atlantic uses the following guidelines for mapping alleys.

  • Alleys should always be mapped if they have a name.
  • Alleys should always be mapped if they are the sole access to a home or business.
  • Alleys should always be set to "PLR"
  • Alleys are normally mapped if they are acknowledged by the municipality.

If an alley does not meet the above criteria, mapping is optional. Leave the name field blank.

Be careful adding alleys which will be closer to the destination pins for house numbers, or from Google, as this can cause all navigation to all the addresses on that block to route onto the alley instead. It may be better not to map these alleys, or you may have to adjust all the address pins to be closer to the actual roads.

Private Road/Dirt Road

Rural farm and logging roads that are never open to the public should be marked as Private Road type to prevent routing. Most should be left off the map unless they serve multiple residences or are longer than 50 meters and has its own street name. Do not create driveways based on other mapping sources and do not delete driveways without consulting the creator first. The Dirt Road/4x4 Trail designation should be reserved for public (state/locality maintained) dirt roads and Forest Service roads, etc, that a user may actually traverse freely during at least part of the year.

MAR Deviation from National Continue TIO Guidance

Restricted areas (border control point, military base) The Mid-Atlantic Region does not use Continue TIOs for when a best continuation is to a restricted area, it is not desired to inform the user prior to entering a military base, controlled industrial area or business, or private residential area (single family houses or apartments/condominiums). Properly established gates using private road segments prevent the majority of entrances into a restricted area unless the destination is only accessible by going into the area.

Toll The Mid-Atlantic Region does not use Continue TIOs for when a best continuation is to a toll. The tolls in MAR are well marked and adding a different primary segment name (with alternate to match the current road name for routing continuation) is not desired. Additionally static tolls now display the toll price for the route.
